Sometimes pulling a sensor is an easy decision, like when Constance gives me "???" readings all night long, getting the ERR1 message multiple times, or when the sensor just falls out of my body from condensed sweat and exercise. Pulling a sensor at those times is an easy decision, but sometimes the receiver oscillates from good readings to "???" enough to tease me. "Oh time to pu . . . oh nevermind it's still good . . . eh getting '???' for a few minutes now so I think I'll pull . . . and we're back to good readings." It's frustrating! Be good or bad!
The main reason I hesitate on pulling a sensor is because I don't know when I'll start getting good readings again. The standard calibration time is set at 2 hours, but I've noticed that it takes my sensors a good 6-12 hours after the calibration time to get going. (Maybe it's something to do with my blood?) And yesterday morning, after having "???" for 3 hours, I took advantage of having a free shower and put on a new sensor after my skin was dry. With the assistance of Tegaderm, I am now able to keep a sensor on for a week easy. Feeling confident with a good placement of the sensor on my left love handle and securing it with Tegaderm, I went to work expecting to calibrate the sensor after 2 hours.
Well, after the calibration, I got about an hour of readings then I got the "???" salute. No biggie, I expected it to get synced back up in a few minutes. But it didn't. Over the course of the next 12 hours, I got "???" with intermitten readings that lasted for less than 30 minutes. By the time I got home, made dinner, and was getting ready for bed, I was still getting "???". I decided to give it overnight to get its act together, or else I would pull the new sensor. When I woke up this morning at 5:00 AM, the sensor finally starting giving consistent readings for the past 3 hours. It's been working like a pro ever since.
|Calibration time = 18 hours ?!|
I'm still incredibly grateful for this device and how it's helped me manage my diabetes, but it certainly tests my patience sometimes.
