Dexcom ONE+ compression lows
Pressure on the sensor, for example lying on it, can change readings. Dexcom says to relieve the pressure and not to calibrate on a reading caused by pressure. (Dexcom user guide, p. 58)
What the maker says to do
- Move off the sensor to relieve the pressure.
- Do not calibrate while pressure may affect the reading.
- Wait for the sensor to recover by itself.
Dexcom ONE+ is not sold in the US. All facts here come from Dexcom's UK and Ireland pages, the UK App Store listing and the outside-US English user guide (mmol/L). Dexcom says Share and Follow may not be available in all regions.
