Alert: Product and Recall NoticesHelpful CGM Calibration Tips
The D-Force is back! This time, MiniMed D-Force, Champion Jim, Busy Bee Cara, and D-tective Lacquitta talk about tips to help you calibrate your Enlite sensor for success.
If you missed the first video, Enlite Insertion Technique and Performance, you can view it here! Have any questions? Let us know in the comments below.
IMPORTANT SAFETY INFORMATION
– Medtronic Diabetes insulin infusion pumps, continuous glucose monitoring systems and associated components are limited to sale by or on the order of a physician and should only be used under the direction of a healthcare professional familiar with the risks associated with the use of these systems.
– Successful operation of the insulin infusion pumps and/or continuous glucose monitoring systems requires adequate vision and hearing to recognize alerts and alarms.
Medtronic Diabetes Insulin Infusion Pumps
– Insulin pump therapy is not recommended for individuals who are unable or unwilling to perform a minimum of four blood glucose tests per day.
– Insulin pumps use rapid-acting insulin. If your insulin delivery is interrupted for any reason, you must be prepared to replace the missed insulin immediately.
Medtronic Diabetes Continuous Glucose Monitoring (CGM) Systems
– The information provided by CGM systems is intended to supplement, not replace, blood glucose information obtained using a home glucose meter. A confirmatory fingerstick is required prior to treatment.
– Insertion of a glucose sensor may cause bleeding or irritation at the insertion site. Consult a physician immediately if you experience significant pain or if you suspect that the site is infected.

And, most importantly, with you – the people who live with diabetes every day.
Hi my name is Erich I am a type one Diabetic and wear a 670 g pump the problem when I Put a new sensor on I have a sensor that bleeds then I have to call Medtronic to order another. One and it is a pain any Ideas need some help thank you Erich
I’m new to this, again, and am having a very hard time! I’ve been on the pump before and don’t remember having such a hard time with the calibrations and such. Something is NOT clicking with me at all!
We’re here to help in any way we can, Michelle. Please give our teammates a call at 800.646.4633, option 1.
My daughter has a virus at the moment so we have upped her basal to try and combat the high blood readings. The sensor is wildly out (partly probably because she has been running high and having to calibrate at this.) e.g. She is coming in at 10mmol and the pump is wanting to suspend before low saying she is 4.3mmol. It won’t accept some of these calibrations and so I have done some readings between what she is and actual to try and bring it closer. It is still really out and I’m wondering should I reconnect to try again or any ideas?
Thanks for reaching out, Emily and I’m sorry for the delay in replying. If you haven’t already, please reach out to your local technical support team to discuss this in more detail.

October 2015. Changed earlier this year to 503G with Enlite Sensor & Contour Next Link BG Meter & Carelink feature. I had a very rough start on the system, but eventually (after replacing my insertion device), things were going good. My doctor was able to view my Carelink uploads and has made effective changes in my insulin rates. Love the technology but I MISS MY old CGM ease of use and reliability. After a good run, I’ve started into a cycle of same problems experienced when I first started with the system. Examples: 10-8-15: BG & SG reading discrepancies (8:15am BG 192 SG 296; 12:20pm BG 131 SG 241^^; 1:30pm – alarms started – predicted low – BG 194 SG 81). Changed sensor for a third time in 5 days and the BG/SG problems continue Calling HELP line is redundant because I’ve been through that process several times and know how & when to calibrate, etc.. Bottom line, I either have a defective “Insertion Device – AGAIN” – BTW, my transmitter tested good – OR my 503G has a problem. Result: I’ve shut down my alarms – so what good is the sensor? I NEED A RELIABLE CGM. Any advice?
Judy, I’m so sorry to hear you’re having a less than optimal experience with your CGM, and can imagine this is frustrating. I will have someone from my team connect with you to try and help.
I have extreme readinfs. My pump/sensor has told me that I am 254 when in reality (by clean finger stick I am 54. Or , like this morning at 6 after trip to bathroom and washing hands, my pump said I was 77, I was 137. I callibrated. 15 minutes later the alarm sounded off. I eventually suspended after an hour. It went to threshold suspend 15 minutes later, then at 730 it told me that I was 63. Finger stick showed that I was 93. I am calibrating 4 times in 24 hours with clean hands. It’s annoying and very frustrating and annoying when it does this at 2 a.m. continuing on for hours. Rarely will the sensor and fingers tick be 20 off.
Beatrice, I am very sorry to hear about the accuracy issues you are having. I would like to connect you with someone from the 24-Hour HelpLine to discuss your experiences in more detail. I will have someone send you an email to connect with you.
Beatrice I have the exact same issues. Been through everything with Medtronic. Toward end of sensor life gets worse.
Helen, I’m sorry to hear you’re having issues with the sensor accuracy. I will have a member of my team connect with you to try and help.
I have the same problems! Or, when your pump suspends at night and reads “65” in the morning, and you check your sugar and it’s 271.
I ALWAYS wash my hands, calibrate between meals when my blood glucose is stable, and test before blousing, but these inaccuracies still mess up my day. 🙁
Alice, I’m sorry to hear about this experience. I’d like to connect you with a member of our HelpLine team to see if they can help. I’ve passed along your information and someone should be reaching out to you shortly.
I understand all the calibration tips you have given us, my problem is; my sensor will tell me I am over 200 and my clean fingers tick says I am 54. Or I will have the opposite readings. For example, this morning at 6 my sensor said that I was 77 when in reality I was 131. I had washed my hands prior to testing. I then calibrated and every darned 15 minutes later the alarms went off, I turned my pump off when by finger stick I got to 107. Still 2 hours later I was still being told that I was 54. Next time I will turn the alarm off. I really hate it when this happens at 2 a.m. I calibrate 4 times in a 24 hr. period.
I am trying to calibrate properly. My problem is I usually calibrate and eat at the same time. I need to start calibrating before I eat, I am just not sure how long between calibrating and then re-taking your glucose reading and putting that I to the pump with the number of carbs I am eating at the meal. Basically I need to know how long I have to wait between calibrating and eating. I have always had trouble with this. Most of the time my sensor is pretty accurate with all things considered. I really need to get on a proper eating schedule, but with a bad case of gastroparesis, it is very hard as I am hardly ever hungry. Usually I have to force myself to eat. I do certain things to make me hungry, because otherwise I could go a whole day without eating. Also I really need to find or better yet organize a support group for diabetics on a pump. Unless you have this crap disease, and you wear a pump as well, otherwise I don’t think you would get it. Maybe I’m wrong, but do you have any suggestions in either starting a group up or joining one. Struggling with diabetes since 1991. On a pun since 12/2004.
Hi Steven. We recommend calibrating 3 to 4 times throughout the day. Here are a few tips on calibrating your sensor:
– You can calibrate anytime during any rate of change. However, calibrating with two down arrows may decrease accuracy until the next calibration.
– Calibrate before bedtime
– Calibrate before insulin
– Enter your meter BG reading into the pump immediately after testing your BG. Do not wait to enter it later.
I will have a member of my team reach out to you to try and help. In the meantime, you may find this article on calibration helpful: http://www.loop-blog.com/how-to-calibrate-your-cgm-system/.
Hi Steven, my understanding is that the sensor is reading your BG as it was ten minutes earlier, so you should be able to eat as soon as you have calibrated-just don’t calibrate right after you eat. We have found a big difference in accuracy when calibrating as sugar is changing, compared with a time of sugar stability.
