@Sam19, this was an exceptional sensor event for us, really the first time we have had a lot of lousy data from a sensor.
In the past, for sites we have used the abdomen several times, and the upper thigh most of the time. In general, we get 2 weeks out of one sensor. It is only in the last couple of days of a sensor that we start getting glitchier data. In general, by the 2nd day we get very good data all the way through, with, on average, a few signal losses for 1/2 hour at a time in 2 weeks or so.
I should say, however, that:
- We spend a long time prepping the site and installing. We clean up with alcohol, clean the transmitter belly up with alcohol, use three layers of Skin-Tac, rub the sensor patch for two-three minutes after install, and tape the edges (it is because my son is a swimmer who swims several times a week).
- we retape the patch multiple times over the (lately typical) 2 week period with 3rd party tape (we have used Hypafix, Tegaderm and Grifgrips so far, planning to try Opsite Flexifix too).
- we try to be very careful calibrating (no more than 2-3 times per day, always calibrate over inside range, always calibrate when very even, good poking practices etc.)
Because we are fairly new at this we try to develop clean processes and follow them rigorously (a habit I carry over from work). Feel free to message me if you want to discuss Dexcom 5 practices on the phone.
