Continuous Glucose Monitors (CGMs) are devices that track blood sugar levels in real-time. They provide valuable information for managing diabetes and alert users to potential issues through alarms. Understanding these alarms and knowing how to respond can improve safety and health outcomes.
Types of CGM Alarms
CGMs can generate various alarms based on glucose readings. Common types include low glucose alarms, high glucose alarms, and rate-of-change alerts. Each serves a specific purpose in helping users take timely action.
Interpreting Alarm Signals
When an alarm sounds, check the glucose level displayed on your device. A low alarm indicates blood sugar is below the target range, while a high alarm suggests it is above. Rate-of-change alerts warn of rapid increases or decreases in glucose levels.
Responding to Alarms
Respond promptly to alarms by testing your blood sugar with a traditional meter if necessary. Follow your healthcare provider’s guidelines for treatment, which may include consuming fast-acting carbohydrates for low alarms or insulin adjustments for high alarms.
Preventive Measures
To reduce false alarms and improve device accuracy, ensure your CGM sensor is properly placed and maintained. Regular calibration and keeping the device updated can also help in minimizing unnecessary alerts.
