I’ve been on Minimed’s CGMS with my 722 for a little while now, and when it works I absolutely love it to death. The data is so invaluable to me, when it works I don’t care how much it costs.
I just wish I never had to change sensors. Every time I do, something screws up.
My very first sensor I put in during training with a Medtronic rep was utter failure. I put it in, fastened the transmitter, and never got the green light. The other girl going through the training with me had hers work right away. This made me very nervous. The rep said for me to give it a while, so I went home and waited. Eventually I was able to get the green signal from the transmitter during lunch.
But then the very next morning, my sensor fell out after exercising. It was very irritated and hurting. I must have just chosen a bad spot.
Got a new sensor and put it on my upper abdomen and it worked right away! And that sensor was wonderful. My readings were pretty accurate too. I left it in 6 days.
Now every time I’ve replaced a sensor since, I get issues during the 2 hour wait period before it asks for your first meter BG. Most often I get “SENSOR ERROR” after maybe an hour. Then I have to start it again, and all works well after an additional 2 hours or so. This is super annoying. Why does this happen? Does this happen to anyone else, and is there a way to avoid it? After it does that first sensor error, I haven’t had any more errors until next sensor.
Well today I got a new one. This time instead of “SENSOR ERROR”, I got “LOST SENSOR” about an hour into the two-hour wait period. And now I can’t get it back. I tried re-connecting the transmitter, which makes me mad because I’ve already taped it down, don’t have more tape at work, and in general do not have a large supply of the IV3000. It didn’t help, and I never got the green flashing light. Wonderful! Did my site just dry up or what? I don’t understand this.
CGMS shows so much promise, but it really seems they have a ton of work to do on it. I wish we were there already. Diabetes is annoying enough without all these technical difficulties.
