Continuous Glucose Monitor and me…part 3

Medtronic's CGMS

“What is that beeping sound? It is very annoying.”

That was one of the comments of one of the Brownie Girl Scouts in my troop. I had to agree, it was very annoying. It was my pump – beeping at me again. Actually, it was the CGM part of my pump. As I mentioned in other posts, I do like the CGM, but I find it awfully needy. (So needy that I stopped using it for a while because the beeping was driving me crazy.)

It beeps when it needs another meter reading for calibration of it’s data. It beeps when it loses signal from the sensor. It beeps when the sensor is done. It beeps with a high blood sugar. It beeps with a low blood sugar. This time, it was thinking that I was having a low blood sugar. Since I just had a cupcake to correct a low, I checked my blood sugar with my meter. Luckily I double checked with my meter, because the CGM was WAY off. My blood sugar was actually high from me over correcting.

In general, I find that the CGM is mostly accurate. But, on days when I have the wildest swings in blood sugar, those are the days that it is the least accurate. Of course, it is the days with the big swings that I need the most accuracy. Well, honestly, I want accuracy every day.
