Getting Started: Preparing for Sensor Application

Before you begin, gather your supplies:

• FreeStyle Libre 2 Sensor: Make sure it's not damaged or expired. Check the expiration date on the box and sensor itself.
• Alcohol Wipe: To clean the application site.
• Launcher: This device inserts the sensor into your skin.
• Flat Surface: A clean, stable surface to work on.

Choosing the Right Spot:

The best place to apply your sensor is on the back of your upper arm. However, you can also use your abdomen (avoiding the belly button). Choose a spot that’s relatively flat, free from scars, and not too hairy.

Important Considerations:

• Rotation: Alternate application sites to prevent skin irritation.
• Hair: If the area is hairy, trim the hair short but don't shave. Shaving can irritate the skin and affect sensor accuracy.
• Exercise: Avoid intense exercise immediately after application.

Applying Your Libre 2 Sensor: A Detailed Process

Step 1: Clean the Application Site

Use the alcohol wipe to thoroughly clean the chosen area of your skin. Let the area air dry completely before proceeding. This ensures a good seal for the sensor.

Step 2: Prepare the Sensor

Remove the sensor from its protective packaging. Do this carefully to avoid damaging the sensor needle. Note the date and time of application, which you'll need to enter into your Libre 2 reader.

Step 3: Attach the Sensor

Firmly press the sensor against your skin at a 90-degree angle. Ensure the sensor is placed flat and firmly against the skin with no wrinkles underneath.

Step 4: Activate the Sensor

Once the sensor is applied, use the applicator to firmly press the sensor against your skin. The sensor will automatically start working. It might take about an hour before the first glucose reading is available.

Step 5: Confirm Sensor Placement

Check that the sensor is securely attached, and there are no air bubbles between it and the skin. If you notice any problems, carefully remove the sensor and try again.

Step 6: Register your Sensor

Use your Libre 2 reader or the LibreLink app to register the sensor and start monitoring your glucose levels. You'll need to enter the sensor's serial number, the date, and the time.

Troubleshooting Common Issues

• Sensor Won't Stick: Make sure the application area is clean and dry. Press the sensor firmly onto your skin. If it still doesn’t stick, try a different location. Avoid areas with significant hair or creases.
• Error Messages: Consult the instructions provided with your Libre 2 system for troubleshooting specific error codes. These codes will help you pinpoint the source of the issue.

Maintaining Your Libre 2 Sensor

• Showering/Swimming: The Libre 2 sensor is water-resistant, but avoid submerging it in water for extended periods.
• Skin Irritation: If you experience skin irritation, remove the sensor and consult your doctor.
• Sensor Removal: After 14 days, carefully remove the sensor using the removal tool provided or gently peeling it off.

Conclusion

Applying your FreeStyle Libre 2 sensor is a straightforward process. Following these steps carefully will help ensure accurate glucose monitoring and ease your diabetes management. Remember to consult your healthcare professional if you have any questions or concerns. Proper sensor placement is key to getting accurate readings from your Libre 2. Following these steps diligently will help maintain your glucose control and ensure optimal health.
