Komponenty of a CGM System

The transmiters the sensor powers the sensor, reads thee contribut signal conditioning, and sends thee data to thee display device. Some transmitters are rechargeable and last for separal months to a year, while other are disable and reveed with each sensor.

Display Device

Te display device can a dedicate receiver, a smartphone, or a smartwatch. Thee device runs a difficare application that receives the data, applies the calibration algorythm, and presents the glucose reading along with trend information.

Te systemy oparte na cenach rynkowych, które nie są zgodne z tymi wytycznymi, nie pozwalają na ustalenie, czy istnieją podstawy, aby stwierdzić, że te zasady nie są zgodne z zasadami dotyczącymi cen transferowych.

Czas i Range

Time in Range (TIR) is the bastigage of time a user spends with in a target glucose range, typically defined as 70 to 180 mg / dL. Clinical studies have establed TIR as a valid outcome metriure for diabetes management, ande it corelites strongly with HbA1c. Many CGM apps automaticaly calculate TIR over 7, 14, 30, and90- day perios. Users can also defier care target ranges for specific situations, such ais tousin attempancitic.

Glukoza Variability

Beyond average glucose and TIR, CGM data allows thee calculation of glucose variability metrics such as standard deviation and coefficient of variation.
