Senseonics Eversense CGM: The Eversense CGM is inserted into the upper arm and was initially approved to be worn for up to 90 days. It is applied at the clinician’s office instead of at home. Data is sent every 5 minutes, and a vibration alarm alerts the patients when glucose falls out of ideal range. The recent Eversense E3 version now has a sensor approved to be worn for up to 180 days, thereby requiring only 2 sensor replacements per year. The system does require regular fingerstick calibrations.
Pros: The Eversense CGM has the most extended wearable sensor life, with an initially approved sensor life of up to 90 days and a recent approval for the Eversense E3 of up to 180 days. Data is sent every 5 minutes.
Cons: Sensor insertion and removal require a physician’s office incision. They also require regular fingerstick calibrations and a 24-hour warm-up after sensor insertion. The transmitter may require daily charging.
Medtronic Guardian Connect CGM: This system provides more detailed glucose tracking data than other CGM devices. It indicates how long a patient’s glucose has been in an ideal range on any given day. The sensor is replaced every seven days. In addition, the Guardian Connect is not available for children younger than 14.
Pros: Shows blood glucose range patterns throughout each day. Provides a reading every 5 minutes.
Cons: The sensor needs to be changed frequently (every 7 days) and may require frequent calibrations. The system is not available for children younger than 14.
