Best Practices For Applying a CGM Sensor
Continuous Glucose Monitors (CGM) are an invaluable tool for those with diabetes, providing real-time glucose readings and helping to prevent dangerous highs and lows. But if you’ve ever used a CGM before, you know that one of the biggest challenges is keeping the sensor in place. Here are the top seven things you can do to prepare for applying your CGM sensor and keep it from falling off.
Often the manufacturer’s instructions provide tips that while might not be obvious are borne true by all the feedback and warranties they deal with.
If you do need to warranty a sensor, you will have a much easier time getting a replacement if you know and followed their instructions.
Before applying your CGM, make sure to clean your skin with an alcohol swab or soap and water. This will help ensure that the adhesive sticks properly and lasts longer. Using an alcohol wipe before application is critical.
It’s important to note that many soaps and body washes contain oils that cause the CGM adhesive to fail.
It’s important to use the alcohol wipe correctly if you are having challenges keeping your sensors attached. The purpose of the Alcohol wipe is to scrub away oils, soaps and other contaminants as well as disinfect the area.
Once you have placed your CGM onto your skin, use gentle pressure around the edges of the device to ensure a secure fit. This will help keep it in place longer and reduce any irritation caused by movement of the device against your skin.
Sensor Placement is important. Look for a location where you are less likely to bump the sensor and you are minimizing the bending of skin under the sensor.
For example: Rotate the a Libre sensor more on the inside of the back of the arm so it’s less likely to get knocked as your moving or sleeping.
A quality CGM patch is recommended to help keep the sensor attached over its lifetime. A patch will work to keep the sensor for becoming dislodged or knocked off prematurely. We highly recommend using a patch on your CGM sensors, especially if you have seen challenges with the sensors coming off.
Wearing loose clothing over your CGM can help keep it in place by reducing friction and tugging between the sensor and other fabrics or surfaces as you move throughout the day.
My Sensor is Still Coming Lose: You’ve tried all the above and your sensors are still coming loose before they should! There are a couple of additional steps you can take to secure your sensor.
