Continuous Glucose Monitor or CGM systems measure glucose levels continuously, displaying a glucose level every 1-5 minutes along with trend arrows to indicate the rate and direction of glucose change. CGM system components include:
Sensor: Sense glucose in interstitial fluid through a thin, flexible, sensor inserted under the skin and adhered to the skin with adhesive.
Transmitter: Transmit sensor glucose information to a display device, which can include a wireless handheld device, smartphone application or a compatible insulin pump.
Glucose trend information provides valuable context that helps the person with diabetes make proactive treatment decisions to mitigate hypoglycemia and hyperglycemia.
CGM reports synthesize large amounts of glucose data (up to 1440 glucose values per day) into reports and graphs, providing insights into glucose patterns.
