Alert: Product and Recall NoticesNicky Answers YOUR Questions about the MiniMed 670G System
Meet our MiniMed 670G system video star, Nicky Williams. We think she’s pretty amazing.
I’ve met a lot of inspiring people with diabetes. But when I was lucky enough to meet Nicky, this 17-year-old who plays soccer, hikes mountains, rides horses, excels in school and is a working through an ambitious “1000 places to see” list, I was wowed. Talk about someone not letting diabetes hold her back.
She’s also been using the MiniMed® 670G system for more than a year as a clinical trial participant and kindly volunteered to let us share her story in photos, video and more. We know you’re all curious to hear what the new system is like in the real world, so we recently asked our social community what you’d like to ask Nicky. Today, she’s answering your questions!
What’s your favorite part of the new system and does the system work well with your daily life?
Diabetes is hard for anyone, but as a busy teenager who just wants to go have fun with friends it can be extremely hard to take care of both. However because my MiniMed 670G system is capable of helping me take care of diabetes, it allows me to focus on being a teenager rather than a diabetic.
My favorite part of the system is how confident the pump, especially the Auto Mode feature, makes me in my diabetes. It takes care of most of my blood sugar fluctuations without me having to even think about it. And I know that if anything even starts to go wrong with my sensor glucose then it will notify me so that I will have plenty of time to deal with it. Because of this it has definitely become an essential part of my busy life. I have tried to go a few days without the system, and have noticed that I am much more anxious throughout the day because I do not have that extra help from the system and have noticed that my blood sugars are much worse on those days.
How does the pump operate during a sensor warm up, and how does the system work if something goes wrong with your sensor? Is there a default operating system is place for these times?
For me it generally takes a few hours to do the entire process of charging my transmitter and putting on a new sensor so that it can warm up. Because of this, I am generally not in Auto Mode and I am running on the default operating system (Manual Mode) for most of the warm up. The default operating system for the MiniMed 670G system is the normal operating systems of most pumps with just the use of constant basal and regular boluses. It is always available and is what the pump reverts to when it is not in the hybrid closed–loop. During this time, as long as all my settings are still accurate, then everything operates well for me.
About the bad sensor, it is not common that I get a bad sensor as long as I wear the tape, which is generally pretty strong. However the few times that I have messed up the sensor’s tape tab the MiniMed 670G system stopped getting information from the sensor. I knew something was wrong with it and have been able to quickly address the issue.
Editor’s Note: In Manual Mode, you can use the system as an integrated pump and sensor like Nicky does, with Suspend on low or with Suspend before low.
Is the new sensor truly accurate? When it is in Auto Mode is it truly auto for basal or does it tell you to go stick your finger then it makes changes?
I have found the sensor to be extremely accurate and is generally within about 20% of my actual blood sugar (I think last time I compared the sensor glucose to my tested bg it was like 6 mg/dL off!). I would say the only time it is kind of far off is when my blood sugar is radically changing so the sensor isn’t able to keep up with it, but it is still only about 30 mg/dL off. Also, when you are in Auto Mode it will take care of small highs or lows but it is not capable of taking care of quick or large changes in my sensor glucose levels, like ones above 200 mg/dL.
Because of this, it is recommended I test by fingerstick and correct when my numbers are high or treat if low. The pump may move you out of Auto Mode and back into the normal basal mode if the sensor doesn’t feel like it is accurate. To get back into Auto Mode I have to prick my finger and calibrate with that blood sugar and possibly follow some other instructions depending on what the pump wants. The system must be calibrated with a blood sugar check every 12 hours or else it will transfer me out of Auto Mode.
Does the 120 mg/dL target make you high? I feel like it should be lower.
The 120 mg/dL target generally works for me; however I have always had the 120 mg/dL target so I personally do not know if a different one would be better or worse. I have however found that there are many other settings I can change if I am running high which can help bring my glucose levels down. For example, if I am running high in the morning then I might change my morning Insulin to Carb ratio to be more aggressive to help keep my blood sugar lower.
Have you been able to sleep better on the system? My teenage son sleeps through the alarms of his current pump!
My numbers have definitely been better and more even throughout the night. I generally coast around the 100-150 range while in Auto Mode on the MiniMed 670G system. The pump is able to take care of most of the rises and dips of my diabetes overnight without me having to do anything. However while it does take care of many of the fluctuations it will generally try to wake me up if I am too far out of range, in which case it changes out of Auto Mode and into just the normal basal rate. To go along with this I also sleep through most of the alarms, unless I am either really low or really high, in which case my body generally naturally wakes me up. Overall though, I found that if I am not woken by any alarms, it definitely helps me to get a better night’s sleep and feel more rested in the morning.
Side note: The alarms are loud, even on vibrate, so if you are sleeping over with a friend you might want to warn them just in case it wakes them up.
How does a system like this manage high carb meals, like a bowl of spaghetti?
In my experience, if I pre-bolus for big carb meals then it handles the meal pretty well and my numbers stay relatively flat. However, if I post-meal bolus, which is what I usually do because I am not good at pre-bolusing, then I generally end up spiking up into the high 200’s for about 2 hours until the insulin is able to catch up. Once the insulin catches up the pump is able bring me back to a good blood sugar range and keep me there even if there are any little post meal fluctuations like a small low.
How do you handle exercise while in Auto Mode?
In activities that I am able to keep my pump on for, like jogs, riding my horse, and hiking, I have found the temp target to be extremely helpful. (The 
Temp Target allows me to change the 120 mg/dL target to 150 mg/dL for a few hours). I didn’t use the Temp Target for about the first 6 months of using the pump, but since I discovered it, I have fallen in love with it! I can’t even count the amount of times it has helped my number stay at 150 mg/dL when I know that without it I would have gone low. However, there are still times when my blood sugar has dropped during exercise. In many of those cases I have been able to start treating the low before it got serious because I was able to watch the arrows on the screen and see which direction my glucose was going.
I started the MiniMed 630G three weeks ago and slated to migrate to the MiniMed 670G in the next few months. My sugars run high when I travel. Has the MiniMed 670G simplified your adjustments when traveling?
I have found that I too run high when I travel and have definitely noticed that the Auto Mode feature helps to make compensating for that easier. It takes care of the most of the general highs for me throughout the day and keeps me more vigilant on them. It’s able to get my numbers down to the 120 mg/dL range overnight and keeps them there throughout the night. However, I also generally need to be a little more generous with my bolusing for the first few days. I think, though that the majority of that issue stems from my diet being more carb heavy while I am traveling.

Important Safety Information
The Medtronic MiniMed 670G system is intended for continuous delivery of basal insulin (at user selectable rates) and administration of insulin boluses (in user selectable amounts) for the management of type 1 diabetes mellitus in persons, fourteen years of age and older, requiring insulin as well as for the continuous monitoring and trending of glucose levels in the fluid under the skin. The MiniMed 670G system includes SmartGuard technology, which can be programmed to automatically adjust delivery of basal insulin based on continuous glucose monitor sensor glucose values, and can suspend delivery of insulin when the sensor glucose value falls below or is predicted to fall below predefined threshold values. The system requires a prescription. The Guardian Sensor (3) glucose values are not intended to be used directly for making therapy adjustments, but rather to provide an indication of when a fingerstick may be required. A confirmatory finger stick test via the CONTOUR®NEXT LINK 2.4 blood glucose meter is required prior to making adjustments to diabetes therapy. All therapy adjustments should be based on measurements obtained using the CONTOUR®NEXT LINK 2.4 blood glucose meter and not on values provided by the Guardian Sensor (3). Always check the pump display to ensure the glucose result shown agrees with the glucose results shown on the CONTOUR®NEXT LINK 2.4 blood glucose meter. Do not calibrate your CGM device or calculate a bolus using a blood glucose meter result taken from an alternative site (palm) or from a control solution test. Do not calibrate your CGM device when sensor or blood glucose values are changing rapidly, e.g., following a meal or physical exercise. If a control solution test is out of range, please note that the result may be transmitted to your pump when in the “Always” send mode. WARNING: Medtronic performed an evaluation of the MiniMed 670G system and determined that it may not be safe for use in children under the age of 7 because of the way that the system is designed and the daily insulin requirements. Therefore, this device should not be used in anyone under the age of 7 years old. This device should also not be used in patients who require less than a total daily insulin dose of 8 units per day, because the device requires a minimum of 8 units per day to operate safely. Only use rapid acting U100 insulin with this system. Pump therapy is not recommended for people whose vision or hearing does not allow recognition of pump signals and alarms. Pump therapy is not recommended for people who are unwilling or unable to maintain contact with their healthcare professional. The safety of the MiniMed 670G system has not been studied in pregnant women. For complete details, including product and important safety information concerning the system and its components, please consult http://www.medtronicdiabetes.com/important-safety-information#minimed-670g and the appropriate user guide at http://www.medtronicdiabetes.com/download-library

LOOP Blog Editorial TeamAt Medtronic Diabetes our vision is to transform diabetes care together for greater freedom and better health. Each word in that statement is important – including the one “together”. We’re a group of passionate people working hard to make a big positive impact on the lives of those with diabetes. But we can’t do it alone. Collaboration is key. With healthcare providers, academic institutions, non-profits and other companies. And, most importantly, with you – the people who live with diabetes every day.
my 670G pump sometimes asks me to calibrate it 2-3 times during the night, which of course is annoying. Most recently this happened when the glucose reading was 114, and when i checked it the external reading was 115, so I recalibrated with that number. Two hours later it woke me again for another calibration. This does not seem correct, given that calibration every 12 hours should be sufficient, especially if it is concordant with the external BG. Please advise on how to fix this annoying problem, so i can sleep!
We can certainly understand how this can be frustrating, and we’d like to help. Our 24-Hour Technical Support Team can review your CareLink with you to get a better understanding of your sensor’s behavior for a better night’s sleep. Please give our team a call at 800.646.4633 option #1.
I was told there is no dual bolus when in auto mode. You can do dual bolus when out of A/M like all the other Medtronic pumps. I was told if I wanted to do a type of dual bolus in A/M to go to Bolus Wizard and see what the amount of insulin it says then go out of it and do half of the amount and in 1 or more hours do the additional half of the bolus.
Hello! When I am using my 670g it would like me to calibrate every 2 and a half hours to continue Automode. How can I change this time so I can calibrate every 6 or 12 hours? I thought the whole point of this was to test my glucose less. I am still doing it 6 times a day…
Hi, Hannah. Our 24-Hour Technical Support team would be happy to review your CareLink reports with you, so we can help you with your calibrations. Please give our team a call at 800.646.4633 option #1.
My question is, how come the 670g pump only allows you to do a dual delivery sometimes. I am trying to use it now and the pump doesn’t let me with some of my bolus’s. I’ve tried to do it with carb bolus alone, I’ve tried to do it with BS alone, and I’ve tried to do it with carb bolus as well as BS bolus. Sometimes the pump will ask me if I want to use the dual delivery and sometimes it doesn’t, it just goes straight to delivering the bolus.
Thanks!
Angela, this would be a great conversation to have with 24-Hour Technical Support team. They can make sure everything is working as designed and can be reached at 800.646.4633 option #1.
I’ve been using the Minimed 670G for about a month now and am experiencing several “insulin flow blocked” alarms through the night. Last night alone it alarmed 24 times between 6:30 pm to 5:54 am. I changed infusion sets, tried 3 different kinds, changed reservoirs and still had trouble. We have troubleshot everything we can think of and still have no answers. What could be causing this? I’ve got to be able to get some sleep!! I will be grateful for any help.
We’d certainly like to look into this for you since this is not the typical experience, Kenneth. If you haven’t done so, please give our 24-Hour Technical Support team a call at 800.646.4633 option #1 at your convenience.
my 670g works well except it takes far to long if I do have an elevated glucose
My a1c has not improved on the pump after almost 2 years. I still run 7.2 to 6.8 but was more like 6.4 on manual mode. still working to improve results. It appears to me that if you miscalculate cho the pump does not have an aggressive enough ability to either keep glucose in range or stop raising rate. one of the issues I have a problem is if I get low 50 BS the correction takes a long time and then it spikes up through the roof.
MY 670MINIMED PUMP KEEPS SHOWING TUBING BLOCKED. i HAVE CHANGED THE TUBING AND RESERVOIR SEVERAL TIMES ERROR 63
I’m sorry to hear this, Karen. If you haven’t already, please reach out to our 24-Hour Technical Support team at 800.646.4633, option 1.
Hi there,
Last night my 670G decided to continue mico-bolusing after my SG had fallen below my 70 mg/dL while I slept, effectively not allowing me to return to a normal glucose. I am quite confused by how the 670G handles lows because mine at least has never suspended for a low when in Auto-mode and in this case, essentially did the opposite. Am I missing something here? I’ve read the manual extensively and will also ask my provider. I just know that anecdotally I’ve had several friends say that they have also had their pumps continue to micro-bolus when they were well below target.
Thanks!
Hi there, Tommy. This is a good conversation to have with our 24-Hour Technical Support team. They can go over your setting and ensure your pump is functioning as designed. Please give them a call at your convenience at 800.646.4633, option 1.
I’m planning to do some snorkling this summer. Is there a product on the market that will provide additional water protection for my Enlite transmitter and sensor?
We appreciate you reaching out, Catherine. Your transmitter and sensor, when connected, form a waterproof seal and can be submerged for up 30 minutes in 8 feet of water. We have not tested any additional products for water protection and are unable to make any recommendations. If you’d like to discuss this in more detail, please give our technical support team a call at 800.646.4633, option 1.
If I am in Auto Mode and I am below 70 will my pump stop giving me insulin or would I stop t manually? I am using the Minimed 670g and the CGM
Great question, Megan. In Smartguard Auto Mode, if you sensor glucose falls below your preset limit, your basal insulin delivery would be suspended until all Auto Mode readiness conditions have been met. To learn more you can refer to the Auto Mode section of your user guide (found here:http://bit.ly/2O7HzHs) or give our technical support team a call at 800.646.4633, option 1.
Hi is there way to do a partial fillup of a reservoir on the 670g. loosing around 70 to 80 nits per refill. thanks
Absolutely, Chip. You can fill your reservoir with as much insulin as you need for the duration of your reservoir and infusion set. If you need particular instructions, please give our team a call at 800.646.4633, option 1.
Do you have to use the guardian sensor with the medtronic pump we tend to have frequent problems with the sensor and it is so expensive
Thanks for checking in, Karen. While our Guardian Link transmitter and Guardian Sensor 3 sensors are not required for use with our MiniMed 670G system as a traditional insulin pump, they are required in order to use SmartGuard Auto Mode. If you’re having trouble, please give our 24-hour helpline a call at 800.646.4633, option 1.
Hey Karrie,
We have spoken before in the past, but i cant seem to get my auto mode to keep me under control, my pump seems to work better in manual mode for some reason and im looking for someone to connect with to get this AutoMode working as advertised.
Hi again, Dan. Our 24-Hour Helpline would be happy to troubleshoot this with you. Please give them a call at your convenience at 800.646.4633, option 1.
Is the catheter for the Minimed 670g Pump and the glucose sensor for the CGM two different things or is it just one?
Hi there, Kathryn! The MiniMed 670G system has 2 insertion sites; on for your infusion set and the other for your sensor. If you’d like to learn more about insulin pump therapy, give us a call at 800.646.4633, option 3.
I will be going to a few beaches this year (one being the Dead Sea). Do I need to do anything special for salt water and sand? I have swam with my pump in fresh water and it was fine.
Bill, we always recommend taking good care of your insulin pump, but your pump should be fine if exposed to salt water or sand as long as it does not get inside the pump. We recommend checking your pump thoroughly for cracks or damage prior to participating in water activities.
We do not have health insurance and the guardian 3 sensor is fairly expensive.My question is , does it HAVE to be changed every 7 days?
Karen, thanks for reaching out and I certainly understand. To answer your question, yes, the Guardian Sensor 3 sensors are approved by the FDA to be worn for up to 7 days and should be changed at that time.
I just had the 2nd transmitter give me issues and I called the help line for questions about them. I ended up telling the operator that the serial # had worn off the outside of the pump. So I had to go into pump settings to give it to her. Now she is making me replace my pump, saying it is required to have the serial # on the outside of the pump. I have been using the 670 for several months now and have enjoyed it. Now with a new pump will I have to keep it in manual mode for 2 weeks before going into auto mode? My current pump is working fine couldn’t I just refuse the new one and keep the pump I have?
That’s a great question, Bob. I’m not familiar with the specifics, but I was able to locate your account and will have a teammate give you a call to go over your options.
I’ve had my pump since January with little issues. But recently it’s been waking me up asking me to enter my blood sugar in the middle of the night. Then it props the auto mode screen. Is this normal? It’s very frustrating!
I’m sorry you are having trouble, Joy. Our 24-Hour HelpLine may have suggestions that can help with this. Please give them a call at 800.646.4633, option 1 and a teammate will be happy to help.
Joy, It’s because you are keeping nice tight control of your BG. Any time your BG runs at below 120 for 2.50 hrs. you get that alarm. So at night if you can keep it at 120 to 130ish, you should sleep through the night without that alarm waking you up. The FDA has some control over the software of this pump, and the fear of a legal issues of someone going low, so they have gone way overboard to keep you at 120 to 150 normal range, they call it. I prefer to stay under 140 myself, for healing and the body rebuilding its self. At 140 it starts slowing down, and the higher your BG gets, it just keeps shutting that down. I think more on the long term effects. But call the Help-Line, you may need to change some settings?
When i look at my Carelink report, should I be looking at the bg or SG to gat an accurate reading of how I am doing?
I’ve been on the 670G and CGM for 5 months. I was in range 73 percent of the time during the first couple of months. About four months in, my pump had a fatal error and it had to be replaced. Up until then I had not noticed with my first pump that my basel was suspended once I bolused. Is that normal? It seems that this causes my sugar to go up.
Great job on your time in range! I’m sorry to hear we had to replace your pump, but yes, the MiniMed 670G pump will suspend your basal insulin while a bolus is being delivered. If you have any questions or concerns, give us a call at 800.646.4633, option 1.
I’ve just received my 670G upgrade (from a 723), but much to my disappointment the Contour Next Link meters I had been keeping at home and work are not compatible. Is there a trade in program to the Link 2.4?
Thanks for reaching out, J. Unfortunately, there is not a trade-in program available for the CONTOUR NEXT LINK meter, but our Supply team can check into your benefits to see if your health plan allows coverage for additional meters. You can reach them at 800.646.4633, option 2.
Using the 670g since Feb 14th 2018, still establishing my relationship with it! Does anyone know which settings in Auto Mode adjust the time for Max and Min basal delivery? The manual says it is determined automatically by your system. I get the alerts at night, usually the Min basal delivery at 2;30 hours, BG is 100 to 120, must test BG and enter into pump to resume Auto Mode. I’ll be talking to my team rep. soon, just wondering if someone knows? Suggestion for the transmitter design team, a transmitter charger that you can attach to the transmitter an hour before you remove it to start a new sensor, then you only have a 2.5 hrs off Auto Mode instead of 3.5 to 4 hours.
Great feedback, David! If you’re looking for an answer about your basal delivery before meeting with your local rep, our 24-Hour HelpLine is also available for these types of questions. You can reach them at 800.646.4633, option 1 and they are available 24 hours a day, 7 days a week.
I have been using the 670G for about 6 months. Many times at night if I am awakened with a low blood sugar alarm, I treat the low blood sugar & record my carb intake on the events log. I would like to resume sleep as soon as possible but my alarm continues to warn that me that my blood sugar is low. Many times I shut off my sensor because I get tired of being awakened by it. What is the fastest way to stop the alarm after I have treated the low bs?
Great question, Janice! I don’t know the fastest way to stop the alarm, but our 24-Hour HelpLine may be able to help with this. They are our pump experts and can review your settings and talk through the built-in safety features of the pump. They may even have some suggestions that may help you get a good nights sleep. Give them a call at your convenience at 800.646.4633, option 1.
Karrie: I, and seemingly every patient with this complaint that has the courage to search for comments on alarms & the 670G and subsequently posted about it has already done this advice. Your response is very well crafted for the unwitting, but to the experienced 670G pump user we see right through it.
We want you to listen. You know we are not wrong. But apparently modifying your firmware and appeasing the massesof actual 670G users is not worth the cost to implement. This is what it will take, and Medtronic Engineering & Leadership is fully aware.
1.) When you pull a battery out to change it, there is ***ZERO*** reason to immediately start screaming alarms. Common sense, wait maybe 30 seconds? (I get the need for it for safety, but currently, you stress EVERY 670G user out with an unneeded alarm because they are changing a battery you told them to change!)
2.) When a blood sugar is High, and the user just entered the ### in the previous action, cancel a subsequent alert that the BG is high and to treat it. Seriously… Why? ***they alrady know they are the ones that entered it***
3.) Same as noted in number 2, for bloodsugar being Low, but again, if the person acknowledges the alarm && the BG is fluctuating, “shutup” montior for any more severe drop and alarm for sure, but, but, but, don’t proceed to tell me my BG is low, approaching low, may need treatment incessantly. (It does this based on your low BG alarm & alert settings: but it doesn’t need to do this if the user has recently acknowledged a low and has treated it). Even better, let the patient state they have treated it then go silent on the subject for 15, 20, or 30m **UNLESS it continues to drop!
4.) Create a night-time sleeping window the patient can program that silences non critical alarms such as battery life remaining, reservoir remaining, min/max automode delivery, automode-anything, bg required and bg recommended. Lets face it, we have used this pump WITHOUT CGMS for decades, it has a doctor programmed insulin profile, it doesn’t need a BG entry at 3AM to keep me alive.
These are all do-able by your engineers, and there is no way the FDA or any governing authority would disagree because none of this is outside of the box of common sense and still allows the medical device to check all of the safety boxes.
We appreciate the feedback, Darren. The MiniMed 670G system is a first of its kind device and we worked closely with the FDA to balance safety and ease of use. We understand everyone’s needs do vary and experience pump users may desire more control over their devices. Changes to features and product use, require extensive research and testing and must be submitted to the FDA for review and approval, which delays the launch of updates. We value the insights of our customers and share all feedback with our development team for future product enhancements. We are committed to continuous innovation and look forward to sharing updates with our community as they become available.
Please urge medtronic’ outreach people to eliminate this useless and misnamed webpage!
After unsuccessfully searching my paper manuals; my downloaded PDF manuals, and finally; google-searching the internet using expressions including various combinations | repeated, “BG required”, auto-mode, solution, trouble, 670G etc. I found another 670G user asking (within a Medtronic Diabetes blogsite) the very same question I have = Landon. Unfortunately even **here** the reply is no answer at all ! In fact of several recent trouble-shooting questions posed by users, many answers were the same non-answer: call the 24/7 support line … which is by traversing the sole phone# and telephone tree and repeating the same personal ID info twice etc.
If this page were replaced by a redirect page “If you have an operational question about use of our products please always call our 24/7 phone# instead of looking for a quicker & more accessible answer here.”
I’m sorry you feel this way, William. Our blog is designed to provide what we hope is useful and insightful information about our products, services and diabetes management in general. While we can answer many general questions, specific issues and device troubleshooting typically require speaking with our 24-Hour HelpLine. This ensures your specific concerns are addressed and our compliance with FDA regulations. I’m sorry if this is disappointing, but please know, we appreciate all the comments and look forward hearing from our community.
The 24 hour help line is a JOKE…..72 mins later and I’m still on hold!!!!
Pathetic but I’m at your mercy because I signed up for this pump and my daughters life depends on it.
Pamela, I am sorry for the long hold times. We are adding more staff to address this concern and look forward to their completion of training. I was able to locate your daughter’s account and understand you were able to speak with someone yesterday. If you still need help, let me know and I’ll have a teammate reach out to you directly.
After i inserted a new sensor, the app said it’s updating. I left it there but after like 12 hours it’s still updating and i can not do anything..what should i do now?
Nagy, you can always clear the “Sensor Updating” alert by selecting “OK”. It will continue in the background. In the future, if it does not correct itself after more than 3 hours, test your transmitter with the tester. You can find more information on testing your transmitter in your user guide or by contacting our 24-Hour HelpLine at 800.646.4633, option 1.
Karrie, I have had issues with downloading reports via care link site, which are reports I would like my doctor to review during my appointment, where they make adjustments to the insulin delivery. I have tried calling the 24 hour help line and been on hold for over 40 minutes every time I call in, and they have not been able to figure the issue out yet. They mentioned giving me another new pump (Third thus far), but if I choose that option I will need to wait at least another month foe data to collect in the pump and then hopefully we can download the necessary information where the doctor can make the adjustments. I wish your help desk for care link would work later than 5pm, as most people have daytime jobs and cannot be on hold for 40 minutes and then take another hour to work with the team to figure this issue out.
I definitely like to help, Mike. Please send me an email to dhelp@medtronic.com with your contact information, the reports you are attempting to download and the error or outcome and I’ll have a teammate reach out to you directly and see if we can get this solved for you.
When calibrating a new sensor I have the expected 2 hour warm up, than a 3 hour calibration, than in 6 hours again, then onto every 12 hours. Every thing I read says there is a 2hour warm up, 6 hour calibration, then every 12. It literally takes all day to get set up, or I’m up at night. Is the 3 hour calibration normal?
Katee, we appreciate you reaching out. If you’re using our MiniMed 670G system, we don’t expect it to request a calibration at 3 hours. It may, however, ask for a blood glucose reading to begin SmartGuard™ Auto Mode. If you ‘d like to talk about this in more detail, give us a call at 800.646.4633, option 1.
Karrie- I have auto mode on and all options switched to on but I don’t see any value. I still have to manually correct when I’m high and the pump doesn’t suspend before a low in auto mode. What am I missing?? So frustrated as I thought this pu.p would do more for me….
That is very interesting, Christy and I can understand your frustration. We’d certainly want to take a look at what’s going on with your pump and see if we can help. Please reach out to our 24-Hour HelpLine at 800.646.4633, option 1 and a specialist will be happy to into this for you.
Can I use the 670g as a regular insulin pump? Without the Guardian sensor and the transmitter? I cannot afford the cost of the sensors. If so, how?
Yes, you can Arlene. While you won’t have access to SmartGuard™ Auto Mode without the Guardian Sensor 3 sensors or Manual Mode features such as SmartGuard™ Suspend before low and SmartGuard™ Suspend on low, we understand this may not be an option. Our 24-Hour HelpLine would be happy to help if you have questions about using the pump portion only and they can be reached at 800.646.4633 option #1. Please know we do have financial assistance plans that can help with your ongoing costs. If you’d like to speak to a team member about your options, please give us a call at 800.646.4633 option #4.
For the past two days I haven’t had a BG reading outside of an 80-160 range. Both the fingerstick and the sensor seem to be confirming that. However, I keep getting kicked out of Auto Mode. I’ve had to calibrate 5-6 times the both of the last two days and each time, the fingerstick is confirming what the sensor is saying. I’m not getting Min/Max Auto Delivery warnings, it’s just saying BG Required, and the blue shield goes gray. It’s super frustrating because it’s happened twice in the middle of the night.
How on earth am I supposed to troubleshoot something like this? Can I get the non OCD software?
Pump: Are you sure your BG is 100
Me: Yes I’m sure.
Pump: Well yeah, but are you REALLY sure?
Me: Yeah I’m REALLY REALLY sure.
Pump: Could you maybe test a couple times just to make sure, this uneasiness is keeping me up at night.
Me: You and me both.
Landon, thank you for sharing this with us and we definitely want to see how we can help, in a non-obsessive way of course. Please call our 24-Hour HelpLine at 800.646.4633, option 1, to speak with one of our teammates. They are available 24/7, so if necessary, we can certainly join your late night conversation.
I am on the 670G & planning a tropical vacation. I know the pump is “waterproof” but I will likely still take it off before snorkeling. What about the CGM? Should I leave it on (as I do when I shower)? Or should I disconnect & take the “shell” part off? Which is better? Thanks!
Patricia, when the transmitter and sensor are connected, they form a water-tight seal to a depth of 8 feet for up to 30 minutes. If you will be underwater for longer than 30 minutes, remove your transmitter and keep it in a safe location. Enjoy your trip!
So the sensor does not have to be “closed up”?
Rosalyn, I’m not sure I understand your question about the sensor, but our 24-Hour HelpLine may be able to help. They can also discuss the features of the pump and your settings to help with any high BGs you may be experiencing. Please know, any changes to your settings will need to be discussed with your healthcare team, but we are happy to help in any way we can.
While I am in auto mode my blood sugars are very high frequently. High, above 300, sometimes above 400. Before using the 670G I never had highs like this. My blood sugars were very good. Maybe it’s my settings. In the Manual it says”your high and low settings apply to auto mode”. How do these setting effect the insulin delivery in auto mode? Can you please explain these settings to me and how auto mode uses these settings?
Thank you, Theresa
Theresa, we are happy to help and I’m sorry you are having trouble. This is a good conversation to have with our 24-Hour HelpLine as they can go over your settings and answer any specific questions you have. You can reach our team at 800.646.4633, option 1.
I have tried to speak to them about it and they tell me this is something I should speak to my doctor about, which I will, next time I see her, But in the meantime, I would like to know what they have to say about the settings. Since this is their line of work, they would have more knowledge about it possibly and maybe my doctor.
Theresa, depending on your question, there are times that we do need to refer you back to your healthcare provider. Send me an email at dhelp@medtronic.com with the phone number associated with your account and I’ll have a specialist give you a call to see what we can do to help.
Theresa,
I has similar problems. My doctor had me change the Max Basil settings. Options/delivery settings/Max basil/bolus. The default was too low. Mine is currently set at 3.0. it was like 2.0. Discuss with your Doctor about what that setting should be for you.
Thanks Tim.
I was originally on the 630 and got the new 670 upgrade. It is absolutely horrible. How would I go about keeping my old pump and return ing this useless innacurate 670?
I am sorry to hear about your experience with the MiniMed 670G system, Justin. Our Customer Support Center would like to help with your concerns and can be reached at 800.646.4633 option #5.
We are interested in the 670G pump for our 15 y/o daughter. If approved by insurance and all, what is the wait time looking like? We realize it’s a closed loop system, but if she wants breaks from wearing the Guardian Sensor 3 is that doable with this pump? And what is the wait time for receiving the Guardian Sensor?
Hi Val. We are currently experiencing a rolling back order on our MiniMed 670G pumps, but they are generally shipping within 2 weeks of their eligible ship date and Guardian Sensor 3s within a week. Our Puerto Rico facility is back up to a 100%, and we are working around the clock to ship orders as quickly as possible.
While we believe you get the most out of our therapies by using the MiniMed 670G system with CGM, we do understand that’s not always an option. She will be able to wear the pump as a standalone device.
If you’re ready to take the next step, please contact your device specialist at 800.646.4633 option #3. They will be able to walk you through the process, including insurance coverage.
My son wears a pump and does not bolus hardly ever. His roommate has had to call the EMTs to revive him from low blood sugar several times. The last time his reading was 17. Would proper bolusing prevent this?
Marlyn, I am very sorry to hear this. This is a good conversation to have with your son’s healthcare provider, as it is specific to his carb intake, activity level and the instructions of his physician. They are best equipped to answer these type of questions, based on your son’s individual needs.
I experienced the “sensor updating” alert for the first time last night. I couldn’t find any information in the user guides but did find a little here. The alert started after I went to bed and didn’t resolve itself so I spent the night being woken up that message being repeated over and over. I only got out of this by removing the transmitter, turning the sensor connection off, waiting 15 minutes and then reconnecting the transmitter and starting the reconnect sensor process. Not sure why this worked but it would have been nice to have this solution posted somewhere. I got it from another 670g user and to be honest, it has a sense of lets-give-this-a-try instead of a known solution. Is there anything wrong with this approach?
Thanks for checking in, Joe. The Guardian Sensor 3 has built in diagnostic technology that continuously monitors sensor health. The “Sensor Updating” alert means that your sensor is not currently reading your glucose values, as it is testing itself. This could last anywhere between 15 minutes to 3 hours. I do recommend speaking with our 24-Hour HelpLine at 800.646.46333, option 1, to discuss how you cleared the alert. They are our experts and can give you the best direction. In the meantime, I will share your feedback about adding this to the user guide with our team.
I frequently recieve this alert and have NEVER had a successful update…everytime it does this, within an hour or two, it tells me “sensor expired” or similar and that i need to insert a new sensor…sometime less than 24 hours after getting this sensor up and running…I have no idea what I’m doing wrong…the 24hr help desk has not been able to help either…any of the 6 times I’ve called them…
That’s interesting, Danika and I’m sure very frustrating. I’d like to see if we can get you some answers. Send me your contact information to dhelp@medtronic.com and we’ll see what we can do to help.
Hi
I have been very frustrated with the new 670G pump. I have gone to two training sessions so far and am scheduled for another one this Tuesday. When it says it is time to calibrate I do so and then it still says I need to add blood sugar amount to continue on auto mode. This also happens when I test and send results to the meter- it still says I need to enter blood sugar. That just doesn’t make sense to me. Sometimes it does accept the reading but I would think thatit already knows the reading anyway.
Brenda
Brenda, I can certainly understand your frustration. In addition to your scheduled training, this is a good conversation to have with our 24-Hour HelpLine. They may be able to offer suggestions that can help with this. Please give them a call at your convenience at 800.646.4633, option 1.
What does “do not calibrate. Sensor updating…” mean?
Steve, this alert means that your sensor glucose value is unavailable temporarily. This alert can last up to 3 hours. If you have additional questions on your sensor, I suggest reaching out to the 24 HelpLine at 800.646.4633, option 1.
Hi, I received my 670G about 5 weeks ago and I seem to be experiencing lost signal alerts more often than I would with my 630. I get a least 1-2 a week, and today I’ve lost the signal more than 4 times! I double tape my transmitter site so I don’t think it’s just a tape issue, and this is day 4 of the sensor (and while I had two lost signals on day 2 of this sensor, today has been unbearable!). I’d chalk it up to a bad sensor and change (and probably will anyway), but given it has happened with other sensors before, wondering if it’s a transmitter issue or something else instead?
I’m very sorry that you are having trouble, Gina. This is a good conversation to have with our 24-Hour HelpLine, as they can go over troubleshooting with you and make sure everything is working as designed. Please give them a call at 800.646.4633, option 1.
I have been using the 670G for a few months, and the micro boluses do not seem to take care of keeping my blood sugar between 120 and 150. Without eating or drinking any carbs, my BS will rise from 115 (for example) to 200. Why don’t the micro boluses take care of this and keep my BS between 120 and 150?
Robyn, the goal of the MiniMed 670G system is to increase the time with glucose values in the target range of 70-180 mg/dL. To get there the mid-point target of 120 mg/dL is used by the target algorithm. For more information, check out the following blog: https://www.medtronicdiabetes.com/loop-blog/10606-2/.
Why does the 670g under estimate correction boluses (>3 times fewer units) in auto-mode compared to manual-mode?
Tim, for more information on how the target algorithm works please check out the following blog: https://www.medtronicdiabetes.com/loop-blog/10606-2/.
Call Medtronic the direct extention for 670g problems is 22020.
Hi my son is using 670 g from last two months and from last week pump is asking for sensor change on daily basis any idea why is that for ?
Good question, Sabeen. I recommend connecting with our 24-Hour HelpLine team at 800-646-4633 then choose option #1. They should be able to answer your questions and get you the help you need.
I’m getting ready to make the transition from the 630g to the 670g. Can the settings from the old device be restored to the new 670g?
Hi David, this will be a manual process but your Medtronic trainer can help if you have any questions. If you upload to CareLink, you can pull a recent device report which has documentation of all of your settings. You can use this as a helpful guide when you’re setting up your MiniMed 670G system.
I have had diabetes since I was 18 years old I just turned 54 . And for the first time in my life I got a 630G which my A1C went from a solid 14 to a 6.7 in three months well I have not ever ever had a 6. nothing ever. And through my life I have lost my leg above the knee and Im legally blind SinseWell Medtronics promised me that I would get a 670G when they came out which they did and I assumed that my insurance would cover . I have the 670G with the transmitter for the Gaudian Link sensorsors. Well my insurance co. Unided Health Care I have . Well I have medicare and Medicaid. They paid for the pump but at first denied to pay for the Contour test strips and the sensors for the Gaurdinan Link. I appealed and appealed and finally got them to cover the test stips but now they are saying my insurance don’t cover the sensors . Ive already filed an appeal for the ALJ hearing finally Ill be abel to say something to the judge over the phone. I don’t know why they are making it hard for me to get every thing I need to make this pump work. Could you please send me a letter or something I can present to the judge that in detail tell about this being a closed loop system, an artificial pancreas. Please email me back with information I desperately need help???
Richard, I’ll have a member of my team reach out to help.
Why does the pump not accept the glucose reading I enter after testing. This usually happens when the is a large difference in actual BG and what the pump is getting from the sensor. If this happens twice the pump says to replace the sensor.
Hi Tim, have you had a chance to discuss this with our 24-Hour HelpLine? If not, I recommend calling them at 1.800.646.4633, option 1.
I just went into Automode this week with the 670. In Automode, the pump has not asked to do a correction bolus regardless of the BG I enter. I have been struggling with ever changing Basal rate needs. I can’t figure out how to correctly give myself a correction in auto mode. Any suggestions?
Chris, the MiniMed 670G system will ask for a correction bolus when needed. If you think you need to adjust your active insulin settings or carb ratio, please talk with your physician.
I am just getting started on my first insulin pump (670). Now this might sound silly but I keep reading about sensors that you need. I just went through my start up box with the rep, and I don’t have any sensors. I know there was a mix up because I received 2 pump start up boxes. I am waiting on the return info for the second start up box. So I guess my question is am I supposed to have a separate sensor unit?
Hi Erin, apologies if this wasn’t communicated to you when your insulin pump shipped. However, your sensors will ship out this fall once we get through those who are in our Priority Access program. It’s important that we keep our commitment to that group and once complete we’ll begin shipping sensors out to those who ordered the pump and haven’t received the sensors.
Just to fulfill my curiosity, what is actually happening when the pump states “Do not calibrate, sensor updating”?
Hi Tim. When your insulin pump states this, it’s due to a temporary situation that the sensor is trying to adjust for. The new CGM, incorporates diagnostic technology that continuously monitors the sensor.
Ok Great! Thanks for responding so quickly.
You’re very welcome!
So is it still in Auto mode during that time or back in manual basal mode?
What kind of things make it need to do that?
Patrick, You can stay in Auto Mode for up to 3 hours while the sensor makes adjustments. This can be caused by shifts in ISIG values or a sensor not properly inserted. If you have specific questions, please reach out to our 24-Hour HelpLine at 800.646.4633, option 1.
What am I supposed to do when it wants to “sensor updating” at 10pm at night and then it wants to calibrate 3 hours later? This is starting to be so frustrating for me. The helpline is no help because I seem to be on hold for so long and the automated system is like going through a maze. This is my first week on the 670g. I was on the 630 for 10 months but it caused me so much anxiety.
Luke, I’m sorry you are frustrated. Our 24-Hour HelpLine is best to discuss this with. If you send your contact information to dhelp@medtronic.com, I can have a teammate call you, to make things a little easier.
When auto mode is in warm-up, is the time necessary for the warm-up extended when the pump goes into suspend mode? Or when I manually return the pump to auto mode (warm up) does the warm-up time start over?
Great question, Tim. Depending on the case, the system will likely prompt you for a new BG reading and should resume within 10-12 minutes.
When in auto mode, is there an option to turn on/off suspend before low or does it do it automatically? I saw in my setting review it says suspend on low is turned off… does that mean if I fall into manual mode, it is turned off?
Rebecca, when in Auto Mode you will not be able to use Suspend on low. The system will adjust your basal insulin delivery to try and keep you as close to the 120 mg/dL target as possible. If you go into Manual Mode, you will need to restart your SmartGuard features (turn them on if they’ve already been previously set-up). Remember that there are several alerts that can be set up, such as a low alert, and there is a default alert at 50 mg/dL.
Karrie, Are you saying that when you go into manual mode you can turn on smart guard features? Or were you just saying its important to remember to put it back into auto when you are finished with the manual mode?
Dave, the SmartGuard technology can be used in both Manual and Auto Mode.
I have received the Email that says Place your order for the MiniMed 670G System, but when I click YES Button on the Email and logging on to the website then it only shows my Profile, and I can’t see any thing says Place the order or anything related.
Could you fix the issue or tell what should I do. Thanks.
Douaa, I have asked someone from my team to reach out and help with placing your order. If you’d like immediate assistance, please give us a call at 800.646.4633, option 3.
I have become very frustrated with the wait time when calling the 800#. Last week I had to call twice in one day, as I needed help to adjust my settings per my Endocrinologist (& first time I was misguided, as my Endo wanted my basal increased by 25%, & the Medtronic rep, instead of setting my temp basal rate at 125%, had me set at 25% – HUGE MISTAKE!!!). Due to a combination of high blood sugars, stress, humidity, I was feeling very very poor….& it was extremely frustrating to be placed on hold for 25-30 minutes, EACH time I called.
Is Medtronic working at increasing the number of call center agents to decrease the wait time, & PROVIDE THEM WITH BETTER TRAINING?
Patricia, our hold times have been longer than normal, but we are working as quickly as possible to get them back in range. In the meantime, I have shared your information with my team and asked that they give you a call to help.
Hi , I have the 630 and am signed up for the 670 priority , I was e-mailed the order form for the 670 on 6/1/17 so I filled it out and gave my credit card # for the $299 the same day. Now I don’t know how I should go about finding out how my order is getting along or if anything is happening .Nobody has contacted me ,I do have a conformation # I went online and there is no info on this order . Can you please direct my next move for I’m kinda anxious and excited to get started on the 670
Thanks Rex
Hi Rex, I have confirmed that your order was placed. You should have received a confirmation pop-up after placing your order. In regard to next steps, we will work on getting your prescription from you physician and verifying your coverage through your insurance. Once your order is ready to ship we will reach out to you. Please be patient with us as we get through these Priority Access upgrades. Thank you!
Went to my Endo today and she said she sent my script to you guys yesterday so it looks like all is going smoothly so far . #gettiinexcited
Thx Rex
So glad to hear it! We should be in touch soon.
I have tons of trouble with the 630 CGM system–it’s great during the first day or two, but after sleeping and inadvertently putting pressure on the sensor (I’m a restless sleeper so I can’t just avoid the location) I suddenly get very low readings (inaccurate ones) that cause my next calibration to fail and then the whole system tells me that I need a new sensor. I have discussed this with the medtronic help line and also with my doctor (who just referred me back to medtronic), and nothing consistently gets me the full six days that the sensor promised. Will the 670 system have these problems? I don’t want to sleep on the sensor and have it suspend my insulin and wake me up because of inaccurate lows (I had to turn off the suspend on low and alert on low for the 630 for this reason) and constantly be having to replace the sensor every two or three days.
Eleanor, I’m sorry to hear of the troubles you are having with your Enlite sensor. I have asked for someone from our Advanced Troubleshooting team to reach out to you. Also, the MiniMed 670G system uses the Guardian Sensor 3, which is an entirely new CGM sensor and is the first and only sensor approved by the FDA to power a hybrid closed loop system. It incorporates diagnostic technology that continuously monitors sensor health.
Does the Guardian 3 use the same sensor as the Enlite? If not, can we trade in unused sensors?
Bryon, no, the MiniMed 670G system uses the new Guardian Sensor 3. Once your MiniMed 670G system ships, if you have any unopened boxes of Enlite sensors, you can call our team at 800.646.4633, option 5 to discuss returns.
If we want to keep our son’s range at 85-120 will that be possible with the 670G? Also, when is it finally going to be released for distribution?
Kristy, the MiniMed 670G system targets a glucose reading of 120 mg/dL. You can’t change this target. We anticipate having the system available for those not in our Priority Access program sometime late summer/early fall.
Is the new CGMS sensor (Version 3, I think) really any more accurate than the previous CGMS sensor version(s)? When using the previous CGMS sensors with my 530g, I found the sensor results so inaccurate that I had to stop using the CGMS. I was getting High/low blood-sugar alarms for issues that didn’t exist . The CGMS would indicate I was at 60 when I was actually closer to 120. It also happened the other way, indicating I was at almost 200, but when I tested I was 138. My results weren’t nearly as accurate as what you’re seeing. However, if I was you, I’d still be concerned using a CGMS sensor that can run from 80%-120% of your actual bloodsugar (within 20%) or could be off by 30 mg/dL (per your example).
I do like that the new pump is waterproof, but if the sensor is only waterproof for 30 minutes, and you need to wear both the sensor and the pump to enjoy the pool, I’m wondering if it has much “real world” value.
Why can’t they make a CGMS that doesn’t require the twice daily synchronization? If I’m already sticking my finger, and I can’t trust the CGMS results, what good is it?
Michael, the Guardian Sensor 3 is our most accurate sensor to date and is the only sensor trusted to adjust basal insulin based on your sensor glucose readings. Please note that all CGM systems require a calibration by fingerstick.
It is way more accurate then the enlite sensor in my 630 was. That thing was always off, the Gaurdian seems to be within 10% all the time, except when I am rising or falling rapidly. It needs a little time to catch up then.
Can you still run extended boluses? My son gets great result with sugar surfing (5.7 A1C) but he will run under 100 (70-100) for an hour after each meal due to prebolusing and only rise later (1-3 hours) even later for slow foods. Will the device prevent him from spending time in the 70-100 range? He currently has a daytime average of about 115 and nighttime average of 110. Will the 120 target prevent that? Also, will it compensate if a site starts to go bad but not completely fails?
Joe, no, with the MiniMed 670G system, while in Auto Mode your son will not be able to do dual or square wave boluses. The system treats to a 120 mg/dL by automatic basal and will help adjust glucose levels as needed. Your son will still need to enter the carbs he’s eating. While the target glucose is 120 mg/DL, the actual range that the system tries to keep each person at is 70-180 mg/dL by driving to that target of 120 mg/dL. Our clinical trial participants found they had good control. You can learn more from Nikhita here: http://bit.ly/2hQsMVe
Thanks. FWIW, I would be fine with his average numbers going up as long as we wouldn’t spend a lot of time over 180 with preboluses. What about sites that start to get resistant on the third day though? Will it just keep pushing more insulin and at some point will you’ve alerted that the insulin has been running high and the site may be getting bad?
Joe, we have a great Facebook Live event with Dr. Francine Kaufman where you can learn more about time in range: http://bit.ly/2oKih6e. As for basal insulin delivery, there is an alarm for Auto Mode max delivery. This alert takes place when your pump has been delivering insulin at your maximum Auto Mode basal delivery rate for 4 hours.
Thanks. Again, being in range is the most important and we are in the 70-180 range over 95% of the time now. That does require active night-time management though. If the nights require less intervention without a major loss in time in range it would be worth it.
I have a very important question about mealtime boluses. My son has certain slow meals like pasta and fried chicken which currently require large second waves from a dual wave bolus. He may receive 2 units upfront and as many as 8 units over the next 2-3 hours which matches his carb ratio. If I bolused for all 10 units worth of carbs upfront he would crash, and no amount of basal reduction would stop it (his basal is only 8 units per day). How can the loop function to prevent lows for slow foods? For a small meal, I see how the loop can eliminate basal to make up for a higher initial bolus, but when the bolus is 10 units and only 2 units is coming upfront, won’t it deliver 10 units and then try to bail him out (which won’t work?)
Let’s say for example that a meal with 60 grams of carbs (slow meal) calls for 6 units, but he usually gets 2 upfront and 4 over 2.5 hours, would I need to bolus for the carbs in two stages, say 30 grams upfront and then another 30 grams after an hour and a half or so to prevent putting too much IOB to keep the system from reversing a low by taking basal off board? The extra 4 units would be half a day’s basal and there’s no way to get that off board fast enough if its all bolused upfront.
We have meals that get bolused 20/80 over 3 hours and the 80% may be equivalent to almost an entire day of basal so it seems that I would still have to manually “split” his bolus to avoid lows with these slow foods.
(Incidentally, with such slow meals, we often have to run 140%-170% temp basals at night for another 4-8 hours, and I think that the loop would do great with those slow nighttime rises after certain foods. Harvard just published a study that pizza can raise blood sugar for over 8 hours, and in our case this is true. We have to run extra, either temp basal or a long square bolus for 6-8 hours AFTER the initial bolus is finished.)
Hi Joe – this is a great conversation to have with your son’s healthcare team to see what works best for him. I do know that some customers currently using the MiniMed 670G system might split up their bolus based on the food since the dual and square wave is no longer available. While the goal of Auto Mode is to use basal insulin delivery to keep you in range, there is also Manual Mode on the system. In this mode you can still use square and dual wave, as well as Suspend before low. These are also great features which may benefit your son.
This was hard for me to deal with initially, but when I eat pizza or something I bolus more conservatively. Because for me pizza is a food that would make me crash and then have highs after. I bolus less for it now, and the pump often will cover me automatically with the auto basal, however sometimes I have to make a correction later. I also sometimes let my pump run outside of auto where I can do extended bolus, but I always have the pump in suspend before low. That feature alone made a huge difference when there was a change in estimated activity. Overall I love this pump, I run in auto most all the time, but the extra features in standard mode are very helpful as well.
Is the 670 much better than the 630 and if so in what way
Donald, I will let the community answer this, but do want to highlight that the MiniMed 670G system is a hybrid closed loop system, which means that when used in Auto Mode, the pump automatically adjusts the delivery of your basal insulin based on readings from our new, most advanced CGM sensor, the Guardian Sensor 3. It also gives you two other SmartGuard HCL technology options: Suspend on low (which is also in MiniMed 630G) and Suspend before low.
Karrie can you please explain the auto-mode and how it relates to the basal rates.? I’m not understanding how they relate..? When in auto-mode, is the basal “off” and the algorithm just gives micro boluses based on trending sugars, does auto-mode micro adjust the preset basal rates.?
Danika, great question! In it’s simplest terms, the Auto Mode feature can automatically increase or decrease the amount of insulin delivered based on your sensor values. Auto Mode provides automated basal insulin delivery that automatically adjusts based on sensor glucose values and individual insulin delivery needs. Other insulin pumps deliver pre-set basal rates, which need to be manually adjusted when insulin needs change based on activity, exercise, stress, hormones etc.
Hi there. I swim 5-6X week for an hour. Would Medtronic suggest I disconnect ? How will the 670 correct for exercise?
Hi Martha, at the time of manufacture, the MiniMed 670G insulin pump is waterproof in up to 12 feet of water for 24 hours at a time. In regard to your question about exercise and the system, please listen to what Cheryl has to say here: http://bit.ly/2oKih6e
After about 5 minutes in my pool, my pump shows three dashes. Then it buzzes and displays “out of range”. Is it not designed to continue giving me cgm readings while I’m under water?
Thanks for your comment, Rosalyn. This is expected behavior when your transmitter is submerged in water. If you have more questions, please let us know.
Can the sensor stay submerged in water for 1-2 hours during swimming for exercise?
Hi there, Kay. When the transmitter and sensor are connected, they form a water-tight seal to a depth of 8 feet for up to 30 minutes. I hope this helps. If you have additional questions, please give our team a call at 800.646.4633, option 1.
I just received the 630g and I am supposed to move to the 670g soon. My a1c is 4.9 and I feel the best around 80. I follow a rigorous Diet and exercise program and I check blood sugars constantly. My biggest reason for wanting the closed loop system is when I play with my children I often forget to reduce basal and end up low. Lows for me tend to result in hours of body aches, whereas being above about 110 causes a loss in vision and headaches. Is it possible to stay around 80 with the closed loop system or would it be in my best interest to stay on a regular pump?
Tracy, this is a great question to discuss with your healthcare provider. They will best be able to talk about your individual needs. I will let you know though that the MiniMed 670G system in Auto Mode has a target glucose of 120 mg/dL and it cannot be adjusted. When in Manual Mode, you do have the option of Suspend before low, which is a new Low Management feature that will temporarily stop insulin delivery if the sensor glucose value is approaching a preset low limit. This is different from Suspend on low (Threshold Suspend) which stops insulin delivery once the sensor glucose values reach a preset limit. It also automatically resumes insulin delivery when sensor glucose levels recover.
I’ve been on the 630G for about 1.5 months, & using the CGM that came with it. I quit using the last CGM because it was frustratingly inaccurate. Will the new CGM be more accurate than this current one? Altho my current one seems mostly better than the previous one, I find that it is highly inaccurate the day before it notifies me to change.
Patricia, I’m sorry to hear that you’re having problems with your Enlite. I would like for our 24 HelpLine to reach out and see if there is anything we can do to assist you. Please email us at dhelp@medtronic.com with your contact information. In regard to the Guardian Sensor 3, it is our newest and most advanced glucose sensor with enhanced accuracy and performance, and a longer 7-day life.
blind user of the 530g with no sensor ,will mini med get sensors out to the people who they have left in the place where have old pump that has what I need all but the sensors. I am really mad about this sense was told that should have the sensors out by dec 22 2017.I would love the chance to have a 630 or the 670 with sensor so could see if could learn to get around in it .Mini med needs to think about the blind sense there are people in need of the voice on the pump.i am willing to learn the new system but can’t get one now sense i have been pushed into the530g just in last 5 months.
Randy, we are working with the FDA to gain approval for the updated MiniLink transmitter, but do not have a timeline on when it will be approved. We will be sure to share updates with our community as they become available.
I am on week 3 of automode and have had some frustrations. I am higher than I have been in years. People say to be patient but I don’t think the system is working for me. My trainer locally is great but I would like another opinion.
Diane, I’m sorry to hear this. I would like to connect you with someone from our 24 HelpLine to see how we can help. I’ve shared your contact information with my team and you should hear something later this week.
Hello Diane,
When I first started in Automode, I had similar results. Then after visiting my doctor, he made 2 adjustments. 1) He adjusted how long the insulin was considered active in my system & 2) He changed my carb ratio significantly from 1/10 to 1/5.
After those changes were made, I had to learn to stop checking my blood sugar as frequently and just let the pump do it’s job. Now I’m at 92% time in range and my high blood sugar has been significantly reduced. In fact, I’ve never seen so many perfect blood sugar readings in my life. 🙂
Kari, this is great to hear! Keep up the great work.
Did your trainer adjust your carb ratio for high time frames? That’s what my trainer did and wow this pump is wonderful.
Question, does a download of the pump data allow you to see how your basal rate is automatically changing so you can better adjust your non-loop settings?
Tere, you will see Total Daily Dose and Basal amounts on average/day in CareLink Personal. However, you cannot make adjustments to your basal settings in Manual Mode based on what Auto Mode is doing because Total Daily Dose changes everyday and will provide basal insulin based on your daily SG readings. Preset basal delivers insulin regardless of your SG readings. If you are concerned about your basal rates, it’s important to talk with your healthcare team.
I want to know if you can swim with it attache
Chad, the MiniMed 670G system is an important medical device and is made to maintain waterproof capability at the time of manufacture. We recommend that you still take care of it and don’t go swimming with it, but the pump will maintain waterproofing if this can’t be avoided.
I swim 4 days a week generally and put on suspend and swim without it. For the most part no warning for 1st hour but after that you get the “no signal” warning. PS. On the side note. For me I figured out how to go all week with a great tape that doesn’t come loose in shower either. I put the TRANSMITTER in the back of my arm, fatty part upper, and works great for me and use IV 3000 tape that Medtronic sells (my insurance covers) and use the 4 ” x 4 3/4″ . Love it big because hard to see if by one self and can’t hardly miss. Then I use the Skin Tac wipes around the edges, then alcohol if to far outside the bandage.
