This is just a “for your info” “for whatever it’s worth” post.
I had a sensor failure this morning that I hadn’t anticipated. And, judging from the failure description choices listed on Dexcom’s online reporting page, I don’t think Dexcom expects the sensor to fail this way either.
The sensor was attached to the (lower) outside of my left arm. When my t:slim x2 pump displayed a CGM result of “–––”, I felt around on my arm for the sensor and was surprised to not feel anything.
Looking closer, I found that while the adhesive tape was still in place on my arm, the socket containing the G6 transmitter and sensor cannula wire had broken away from the adhesive tape. Huh?
The Dexcom online report page seems to focus primarily on adhesive tape failure as the reason a sensor would “fall off”. The recommended solution is to apply some sort of sensor tape overlay patch.
But apparently even if the tape stays in place the sensor can still “fall off”. And I don’t think Dexcom’s overpatches would fix this.
