How CGM Works
You have to insert a small wire underneath the skin using an automatic applicator. It comes with an adhesive patch to hold the CGM meter in place. It enables you to measure glucose levels during the day and night.
The sensor wire has a connection with a reusable, small transmitter to send the data. The technology of the CGM meter varies from company to company. But the latest ones send the notifications alerts in the CGM app. The patients have to download and stay connected with the app.
The basic versions include a sensor, transmitter, and monitor. Locating the sensor on the belly areas, you can measure glucose levels in the body fluids. The transmitter connected to the sensor sends information to the monitor. It also gives continuous and accurate results. You may receive alerts when glucose levels reach a certain threshold.
