Clotted Dexcom Sensor.
(That's easily one of the grossest blog post titles I've had in the past seven and a half years. Clotted? Blech. Sorry about that.)
Last week, I needed to give the real estate on my thighs a little breathing room, so rotated my Dexcom sensor up north to live on the back of my right arm for a few days. Chris helped me out with the sensor application, with me preparing my skin, sticking the adhesive patch where I want it, and then asking him to, "Oh, do it carefully okay because it might pinch a little and ..." as he unclips the sensor applicator after half a second and says, "It's done." (When I'm not controlling the needle, I bug out. Pain management control freak, right here.)
"Oh shit ... it's bleeding," he said, looking down at the sensor sans transmitter, and we both watched the space beneath pool with blood.
"Eh. Hopefully it still decides to work. Can you snap the transmitter in, and I'll fire it up?"
We finished up our respective tasks (he winced when he clipped the transmitter in, expecting it to hurt me, and I queued up the new sensor. And for a week, this thing gave me spot-on results. Meter said 183 mg/dL? The Dexcom gave the exact same result. Meter claims 89 mg/dL? The CGM confirmed that number, along with the added clue of a downward sloping arrow. This sensor was, by far, the most accurate one I've seen for the G4.
Which is why I was so surprised (and horrified) to pull the sensor out last night and see the nastiest blood clot stuck on the end of the sensor wire, and dried blood pooled in the sensor base.
(This post has officially become a gross post ... a "grost.")
My faith in the G4 is now that much stronger ... even when I'm working with a clotted sensor, it still fires out some on-point results. Now if only my pancreas would get on this "I work despite being slightly compromised" bandwagon ...
