Dexcom ONE - How to replace your sensor

Learn how to seamlessly replace your Dexcom ONE Continuous Glucose Monitoring (CGM) System (https://www.dexcom.com/en-gb/dexcom-o...) sensor with this step-by-step guide. The Dexcom ONE sensor is designed to last for 10 days and the app* (https://www.dexcom.com/en-gb/dexcom-apps) keeps you informed with alerts as the end of your sensor session approaches.

1. Alerts - notify you 24 hours, 6 hours, 2 hours, and 30 minutes before your sensor session automatically ends.

2. Removing the Old Sensor and Transmitter:
• Gently peel off the adhesive patch and transmitter from your body, similar to removing a bandage
• To remove the transmitter, push down on the lip and break the wide end of the transmitter holder, then pull it out. Keep the transmitter for use with your next sensor

3. Starting with a New Sensor:
• In the app *, tap 'Start New Sensor' and enter the new sensor code
• The app also allows you to scan the sensor code by taking a picture of it
• Insert your new sensor and reattach your current transmitter. If needed, refer to the in-app instructions or your printed instructions for a refresher on sensor insertion

4. Sensor Warm-Up:
• Confirm the insertion of your new sensor and attachment of the transmitter in the app*
• Start the sensor warm-up, which will take two hours to complete

5. Ending a Sensor Session Early:
• If you need to end your sensor session early, go to 'Settings' in the app*and tap 'Stop Sensor Session'
• Remember to always stop the sensor session in the app *before physically removing the sensor and transmitter
