A Continuous Glucose Monitor (CGM) can be a transformative device for managing diabetes, offering a constant stream of data to guide your decisions. To get the most accurate and reliable information, proper care and maintenance are essential. This article is your ultimate care tool and guide about CGM, designed to help you master your device. By understanding best practices for various CGM uses and maintenance routines, you can ensure your CGM works effectively, providing the insights you need to manage your health with confidence. At Doral Health & Wellness, we have all the answers you need.
Preparing for Sensor Insertion
The foundation of accurate CGM readings begins with proper sensor application. A clean, well-chosen site ensures the sensor can function correctly for its entire lifespan.
Choosing the Right Spot
Most CGM manufacturers approve specific areas of the body for sensor placement, typically the back of the upper arm or the abdomen.
- Rotate Your Sites: Never use the same spot twice in a row. Rotating insertion sites gives your skin time to heal and prevents the buildup of scar tissue, which can interfere with glucose readings.
- Find a Good Location: Look for a spot with an adequate layer of subcutaneous fat. Avoid areas with bones, muscles, scars, tattoos, or irritation. Also, steer clear of spots that will be easily bumped, rubbed by clothing waistbands, or constricted while you sleep.
- Clean the Area: Before insertion, wash the area with soap and water, then dry it completely. Many users also wipe the site with an alcohol prep pad and allow it to air dry to ensure it is free of oils and lotions that could weaken the adhesive.
Your Ultimate Care Tool and Guide about CGM: Sensor and Transmitter Care
Once your sensor is in place, a few simple steps can help it stay secure and transmit data reliably for its full wear time.
Securing Your Sensor
Keeping the sensor firmly attached is crucial. A loose sensor can lead to inaccurate readings or fall off completely.
- Adhesive Patches: Consider using an overpatch—a larger adhesive patch that goes over your CGM sensor—for extra security. This is especially helpful if you are very active, swim frequently, or tend to sweat a lot.
- Skin Adhesives: Some users apply a liquid skin adhesive, like Skin-Tac, to the skin before inserting the sensor to create a stickier surface. Let it dry for a minute before applying the sensor.
Transmitter Maintenance
The transmitter is the reusable brain of your CGM system. Proper care ensures it lasts as long as it should.
- Keep it Clean: When you change your sensor, gently wipe the transmitter with an alcohol pad to remove any adhesive residue.
- Charge It Properly: If your transmitter is rechargeable, follow the manufacturer’s instructions for charging. Avoid overcharging or letting the battery drain completely.
- Store It Safely: When not in use, keep your transmitter in a clean, dry place at room temperature.
Maximizing Your CGM Uses and Data Accuracy
A well-maintained CGM provides a wealth of data. The goal is to ensure that data is as accurate as possible.
- Stay Hydrated: Dehydration can affect CGM readings, causing them to read inaccurately high. Be sure to drink plenty of water throughout the day.
- Calibrations (If Required): Some CGM systems require occasional calibrations with a traditional fingerstick blood glucose meter. For the most accurate results, calibrate when your glucose is stable (i.e., the trend arrow on your receiver is flat).
- Understand the Lag Time: Remember that CGMs measure glucose in the interstitial fluid, which lags behind blood glucose by about 5-15 minutes. This is normal, but it’s important to keep in mind, especially when your glucose is changing rapidly. When in doubt, or if your symptoms don’t match your CGM reading, confirm with a fingerstick.
When to Seek Professional Guidance
