The Dexcom G6 has 3 parts including a sensor, a transmitter and a receiver (reader or compatible smart phone). The sensor is inserted under the skin, and the Dexcom G6 transmitter is attached. Once the transmitter is attached to the sensor, it is waterproof. The device can be worn for up to 10 days. The Dexcom G6 is compatible with many devices. It can send data to a Dexcom G6 receiver, the Dexcom G6 App on a compatible smartphone, and the Tandem X2 insulin pump. Data can also be viewed on an Apple Watch, as long as the person wearing is it using the G6 App. You can share data with up to 5 followers when using a smartphone as a receiver. If you are using ONLY the receiver that came with the device or only a t:slim pump, you cannot share data with others.
Other features and considerations:
- Treatment decisions (calculating insulin doses) can be made with G6 data.
- The device does not need to be calibrated with a blood glucose meter, except under rare circumstances.
- You should always use a blood glucose meter when your symptoms don’t match the readings on the CGM, when the device is not displaying BOTH a number and and arrow, and for very high and very low glucose readings.
- You may need extra tape or an adhesive wipe like Skin Tac to help keep the sensor on for 10 days, especially if you spend a lot of time outside or in the water. If your sensor falls off in fewer than 10 days, contact Dexcom directly for a replacement.
- Acetaminophen (Tylenol) does not affect glucose readings on the G6.
Note: The Dexcom G4 and G5 will be retired in June 2020.)
