Today we hear from Celeste Cooper, who offers up some helpful sensor tips – whether you’re just starting out or nearly CGM pro! For even more resources, visit the Help and Support section of our Website.
My name is Celeste Cooper and I am a 15 year pump user and now have 6 years of sensing experience. I’ll admit, I have never written a blog and have read very few. My brain works better when there is no cell phone, internet or TV, so I see the bright side of power failures. My brain often feels bombarded with too much information. But still, I love my sensor……. how can that be? Because it gives me critical information that is immediately helpful, like getting the weather instead of the stock report. But loving it came slowly, after learning when I should believe it and what to do so that I could believe it most of the time.
If you are new to CGM you likely have had lots of questions and maybe some moments of frustration trying to find answers to those questions. The truth is, some things you can learn from books and websites, some from your trainer, and some only from experience. (Remember learning how insulin worked in your body when you were first diagnosed?) So, some of the most useful information about CGM, I have learned for myself and from talking to other sensor users.
The most important factor in sensor accuracy (in my humble opinion) is when you calibrate, and I think the first calibration after placing a sensor carries the most weight.
I am sure your trainer has taught you when not to calibrate; you’ve also learned it from the product workbooks:
Don’t calibrate when your BG is rapidly changing (i.e. after eating, exercise, etc.)
Don’t calibrate when you have up or down arrows. (That’s fine, but before the first calibration, there are no arrows to guide you!)
There is another extremely important factor to consider in that first calibration and that is “is the sensor wet enough”? I find making sure it’s in a part of my body that has sufficient fat for it to settle in and become thoroughly bathed in interstitial fluid is key. So is waiting the full 2 hours until after you get the “Enter BG” alert to do that first calibration.
Making sure the sensor stays fully inserted is also important, I think. If it comes out even partially, that can affect sensor accuracy. Putting a Band-Aid across the transmitter to secure it works for me, but I know of others who like the clear IV3000 tape.
So there’s my opinions and tips – what are yours?
Stay healthy and may you be happy with your readings!
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.
