Continuous Glucose Monitoring Overview

Device: Guardian Connect

Continuous Glucose Monitoring (CGM) is a technology that allows you to measure glucose levels in real-time throughout the day and night.

The Guardian Connect CGM System is made up of three parts. The sensor, a transmitter and a monitor.

* The transmitter must be within 20 feet (6.1 meters) of the Guardian Connect app in order to send sensor readings.

The sensor is inserted under the skin, so it is in contact with the fluid between your cells, called interstitial fluid. The transmitter is connected to the sensor and the sensor then measures the glucose in the interstitial fluid and sends this information to the transmitter. The transmitter then wirelessly sends this data out to your device.

Glucose is always moving between the blood and interstitial fluid. Blood glucose (BG) meters measure glucose levels in the blood and sensors measure glucose levels in the interstitial fluid.

Continuous Glucose Monitoring (CGM) lets you see your glucose values when you are not checking with your home BG meter. You will get up to 288 sensor glucose readings every 24 hours, filling the gaps between your BG checks. CGM can alert you to your high and low glucose values and show you the speed and direction that your glucose levels are moving.
