INS and Hyperglycemia: To date, two types of CGM systems are available9,10: (i) intermittently scanned device (isCGM) or “flash monitoring,” implying scanning near the sensor, and devoid of alarms for hypo- or hyperglycemia excursions; (ii) real-time (rtCGM) device directly connected to the sensor, requiring a calibration by capillary blood glucose twice a day (except for the Dexcom G6), which can be set to alarms, warning the user of high or low glucose levels, and coupled to the insulin pump (sensor-augmented pump treatment).
