Before inserting your Dexcom G7 sensor, gather the necessary materials: the applicator with built-in sensor, alcohol wipes, and check to make sure your sensor is compatible with your Tandem Diabetes Care insulin pump.
Next, choose a suitable sensor site on the back of your upper arm, ideally an area with some padding. Avoid placing the sensor over bones, irritated skin, tattoos, or areas that are frequently bumped.
Once you’ve completed these preliminary steps, follow the instructions below:
- Wash and dry your hands thoroughly
- Clean your sensor site using an alcohol wipe
- Unscrew the cap from the Dexcom applicator. Do not touch inside.
- Place the applicator against your skin
- Press the applicator button to insert the sensor
- Remove the applicator. The patch and sensor will remain on your skin.
- Throw away the applicator according to your local guidelines for disposal of blood-contacting components
