Replacing a Dexcom sensor is a relatively straightforward process that can be completed in a few easy steps. If you're new to using a continuous glucose monitoring system (CGMS) like Dexcom, it's essential to understand how to replace the sensor to ensure accurate glucose readings and optimal system performance. In this article, we'll walk you through the 5 easy steps for Dexcom sensor replacement.
Understanding Dexcom Sensors
Before we dive into the steps, let's quickly review what Dexcom sensors are and how they work. Dexcom sensors are small, flexible devices that are inserted under the skin to measure glucose levels in the interstitial fluid. They're designed to provide real-time glucose readings, alerting you to high or low glucose levels, and helping you make informed decisions about your diabetes management.
Why Replace Dexcom Sensors?
Dexcom sensors have a limited lifespan, typically lasting around 7-10 days. After this period, the sensor's accuracy and performance may start to degrade, which can lead to incorrect glucose readings. Replacing the sensor regularly ensures that you receive accurate and reliable glucose data, enabling you to manage your diabetes effectively.
Step 1: Prepare for Sensor Replacement
Before starting the replacement process, make sure you have the following items:
- A new Dexcom sensor
- A sensor applicator
- A transmitter (if you're using a Dexcom G6 system)
- A compatible device (such as a smartphone or tablet)
It's also essential to choose a suitable location for the new sensor. Dexcom recommends inserting the sensor on the back of your upper arm, about 2-3 inches from the top of the shoulder. Avoid areas with scar tissue, tattoos, or muscle mass.
Step 2: Remove the Old Sensor
To remove the old sensor, follow these steps:
- Wash your hands thoroughly with soap and water.
- Locate the old sensor and gently grasp the sensor wire.
- Slowly pull the sensor wire out of your skin at a 90-degree angle.
- Remove any adhesive residue from the skin using a gentle adhesive remover.
Step 3: Insert the New Sensor
To insert the new sensor, follow these steps:
- Take the new sensor and remove the protective covering from the adhesive side.
- Place the sensor on your skin, aligning it with the applicator.
- Hold the applicator at a 90-degree angle and press the trigger to insert the sensor.
- Make sure the sensor is fully seated and the adhesive is securely attached to your skin.
Step 4: Pair the Sensor with Your Device
Once the new sensor is inserted, you'll need to pair it with your compatible device. Follow these steps:
- Open the Dexcom app on your device and navigate to the "Sensor" menu.
- Select "Pair Sensor" and follow the on-screen instructions.
- Enter the sensor code (found on the sensor packaging) to complete the pairing process.
Step 5: Start the Sensor Warm-Up Period
After pairing the sensor, you'll need to start the warm-up period. This allows the sensor to calibrate and provide accurate glucose readings. Follow these steps:
- Wait for the sensor to complete the warm-up period (typically 2 hours).
- During this time, avoid calibrating the sensor or taking any glucose readings.
- Once the warm-up period is complete, you can start using the sensor to track your glucose levels.
By following these 5 easy steps, you can successfully replace your Dexcom sensor and continue to manage your diabetes with confidence.
Additional Tips and Reminders
- Always follow proper hygiene and infection control procedures when handling the sensor and applicator.
- Avoid sharing sensors or reusing applicators to minimize the risk of infection.
- If you experience any issues or errors during the replacement process, consult the Dexcom user manual or contact their customer support team.
