Step 4: Setting Up Alerts and Notifications

Once you have successfully paired the Dexcom G6 sensor and transmitter with your phone, it’s time to set up alerts and notifications. These features are extremely useful as they enable you to monitor your glucose levels and receive timely notifications if there are any abnormal changes.

To get started, open the Dexcom G6 mobile app on your phone, and navigate to the settings menu. Look for the “Alerts” or “Notifications” option and tap on it to access the settings for configuring alerts.

  2. High Glucose Alert: Similar to the low glucose alert, this alert will notify you when your glucose levels are above a certain threshold. Again, you can set the desired high glucose value and select an alarm sound.
  3. Urgent Low Soon Alert: This alert is particularly useful if your glucose levels are dropping rapidly. It notifies you when your glucose levels are predicted to reach a critically low level within a specified timeframe.
  4. Delayed Sensor Alert: The delayed sensor alert reminds you to replace your sensor when it is nearing the end of its lifespan. It helps ensure that you always have accurate glucose readings by prompting you to change the sensor in a timely manner.
  5. Custom Alerts: Dexcom G6 also allows you to create custom alerts based on your specific needs. For instance, you can set up an alert to remind you to take medication or to log your food intake.

Once you have configured the alerts based on your preferences, make sure to save the settings. You can also choose to enable vibration alerts in addition to the audible alerts. This offers discreet notifications when you’re in a meeting or a public setting.

It is important to note that setting up alerts and notifications may vary slightly depending on the specific mobile operating system you are using. Dexcom G6 is compatible with both Android and iOS devices, but there might be minor differences in the menu and settings layout.

By setting up alerts and notifications on your Dexcom G6, you can stay informed about your glucose levels throughout the day, helping you make necessary adjustments to your lifestyle and manage your diabetes more effectively.

Step 5: Calibrating the Dexcom G6 Sensor (if required)

Calibrating the Dexcom G6 sensor is an essential step to ensure accurate glucose readings. Calibration is typically required when you first start using the sensor and at least every 12 hours thereafter. Follow these steps to calibrate your Dexcom G6 sensor:

1. Before calibrating, ensure that your sensor has been inserted properly and has been running for at least two hours. This allows the sensor to stabilize and provide consistent readings.

2. Wash your hands thoroughly with soap and water to remove any residue that could affect the accuracy of the calibration.

3. Check your glucose levels using a standard glucose meter. Ensure that the reading is stable and reliable.

4. Open the Dexcom G6 mobile app on your phone and navigate to the calibration menu.

5. Enter the glucose value from your standard glucose meter into the app’s calibration screen. Make sure to type the value accurately to ensure precise calibration.

6. The app will process the calibration value and update the sensor’s calibration data. Wait for a few minutes for the calibration to take effect.

7. After calibration, the Dexcom G6 sensor will use the entered glucose value to improve the accuracy of the continuous glucose readings.

8. Repeat the calibration process every 12 hours, or as recommended by your healthcare provider.

It is important to note that calibrating the Dexcom G6 sensor is not required for everyone. Some users may not need to calibrate the sensor, as it has advanced algorithms that can provide accurate readings without calibration. However, if you are uncertain, it is always best to consult with your healthcare provider for personalized guidance.
