This is my fifth day using the DexCom 7+ and also my first simultaneous diabetes equipment fail.
I posted this story on my blog (http://sugarbump.wordpress.com) but thought I’d post it here as well. In short, I woke up feeling all sorts of weird. My DexCom receiver and transmitter had somehow lost communication (or rather, I had ??? on the screen and no readings for the past hour or more) and was unable to alert me that my bg had been climbing (I have the high alert set to 200). A fingerstick said bg was 361, and as I gave myself the bolus, I felt around my OmniPod and realized there was a leak. A pod change revealed that the cannula was bent (I had changed my pod 3 hours prior).
I realize I won’t know the cannula is bent or otherwise not delivering insulin properly until my bg climbs like that, but I’m more concerned about the loss of communication between the Dex parts. The sensor is on my lower back, and I sleep on my stomach, so the only things in between it and the receiver are my shirt and blanket.
Any ideas here or on my blog would be greatly appreciated! Thanks in advance!
