Are you tired of dealing with failed Dexcom sensors? You're not alone. Many users of the Dexcom continuous glucose monitoring system have experienced frustration with sensors that fail to provide accurate readings or stop working altogether. Fortunately, replacing a failed sensor is a relatively straightforward process that can be done at home with a few simple steps.
Understanding Dexcom Sensors
Before we dive into the replacement process, it's essential to understand how Dexcom sensors work. The Dexcom sensor is a small, flexible electrode that is inserted under the skin to measure glucose levels. It is connected to a transmitter that sends data to a receiver or a compatible smart device. The sensor is designed to provide accurate glucose readings for up to 10 days, but sometimes, it may fail to work properly.
Why Do Dexcom Sensors Fail?
There are several reasons why a Dexcom sensor may fail. Some common causes include:
- Incorrect insertion: If the sensor is not inserted correctly, it may not provide accurate readings or may fail to work altogether.
- Sensor damage: The sensor may be damaged during insertion or due to external factors such as exercise or accidental bumps.
- Adhesive issues: The adhesive that holds the sensor in place may not be strong enough, causing the sensor to come loose or fall off.
- Manufacturing defects: In some cases, the sensor may be defective right out of the package.
Replacing a Failed Dexcom Sensor
Replacing a failed Dexcom sensor is a relatively simple process that can be done at home. Here are the steps to follow:
- Gather the necessary supplies: You will need a new Dexcom sensor, a transmitter, and a receiver or compatible smart device.
- Remove the old sensor: Carefully remove the old sensor from your skin, taking care not to touch the electrode.
- Clean the area: Clean the area where the new sensor will be inserted with soap and water.
- Insert the new sensor: Insert the new sensor at a 45-degree angle, using a gentle pushing motion.
- Secure the sensor: Secure the sensor in place with the adhesive strip provided.
- Pair the new sensor: Pair the new sensor with your transmitter and receiver or compatible smart device.
Tips for Successful Sensor Replacement
- Follow the manufacturer's instructions: Make sure to follow the manufacturer's instructions for inserting and securing the sensor.
- Choose a suitable location: Choose a location for the sensor that is comfortable and won't be subject to excessive movement or irritation.
- Avoid reusing sensors: Avoid reusing sensors, as this can cause inaccurate readings or infection.
- Keep the area clean: Keep the area around the sensor clean and dry to prevent infection.
