The Dexcom G7 is a revolutionary continuous glucose monitor (CGM) offering a simplified, less-painful application process compared to its predecessors. This guide will walk you through the steps of attaching the Dexcom G7 sensor, ensuring a comfortable and secure fit.
Preparing for Application
Before you begin, ensure you have the following:
- Your Dexcom G7 Sensor: Check the expiration date and make sure the sensor is undamaged.
- Alcohol Wipe: Clean the application site thoroughly.
- Application Site: Choose a suitable area on your abdomen, upper arm, or thigh. Avoid areas with scars, bruises, or excessive hair.
- Dexcom G7 Transmitter: Ensure your transmitter is charged and ready to pair.
Step-by-Step Dexcom G7 Sensor Application
-
Clean the Application Site: Use the provided alcohol wipe to thoroughly clean the chosen area on your skin. Allow the skin to dry completely. This prevents irritation and ensures proper sensor adhesion.
-
Remove the Sensor: Carefully peel back the protective film from the sensor. Avoid touching the adhesive side of the sensor.
-
Apply the Sensor: Firmly press the sensor onto your clean, dry skin. Make sure the sensor is completely flat and adheres to the skin. Avoid applying it over creases or folds in your skin.
-
Hold Firmly: Maintain pressure for at least 30 seconds to ensure a secure seal.
-
Pairing the Sensor and Transmitter: Follow the instructions in the Dexcom G7 app to pair the new sensor with your transmitter. The app will guide you through the process. This step is crucial for accurate glucose readings.
Troubleshooting Common Issues
-
Sensor Won't Stick: If the sensor isn't adhering properly, try cleaning the area again and ensuring the skin is completely dry. Excess hair in the application site can interfere with adhesion. You may need to shave the area gently. If problems persist, contact Dexcom support.
-
Sensor Error Messages: The Dexcom G7 app will display error messages if there's an issue. Consult the app's troubleshooting section or contact Dexcom customer support for assistance.

Keep the Sensor Dry: Avoid submerging the sensor in water for extended periods. While shower-proof, prolonged water exposure may affect sensor performance.

Regularly Check Sensor Adhesion: Ensure the sensor remains securely attached throughout its lifespan.
