So, I lost my sensor yesterday. I had problems on Wednesday; I had a Weak Signal for awhile then got a Lost Sensor, even when I held the pump right next to the sensor. So I reached the conclusion the battery must be dead. I couldn’t tell because the sensor readings were all blank, after all, it couldn’t read with no signal and I couldn’t access past sensor data either (DUMB) to see if this was a low battery. So I recharged the battery and reconnected and went through the whole calibration process.
Yesterday, I got a Cal Error about 30 minutes after my first calibration. On my second try, where my blood sugar was exactly the same as the first time (ruling out blood sugar fluctuations as the problem) I got a second Cal Error and then a Sensor Failed.
So, I ripped it off and started over. What surprised me was how soft the sensor canula was; much more flexible and thin than an infusion set. I had a small red spot at the insertion site, but it looked better within the hour.
Things are back on track, and I had eight days wear with my first sensor, so not too bad. I got some advice from Noel that inserting the sensor at 80-85 degree angle helps prolong the life. I tried it (I think), so we’ll see.
Accuracy has been good, but not as close as the Navigator. Maybe 40- 50 point spreads on occasion, but I think my Freestyle Flash runs high when I calibrate. I haven't done a comparison as I ran out of BD strips, so will do soon enough.
I have pictures to post, but I will have to do later.
