Loop mode makes it possible to synchronize the components once they are properly setup and functional (the Dexcom G6 sensor sends a glucose measurement every 5 min and the pump delivers insulin).
When the loop mode is activated, it is considered to be a hybrid closed loop system.
Loop mode will help keep the patient closer to his target blood glucose level, which he selects. Every 5 minutes the system evaluates the optimal dose of insulin to deliver (basal change / stop, meal bolus, correction bolus) to the patient and sends this personalized recommendation to the insulin pump.
This continual assessment takes into account the current glucose levels, glucose trend, the hypoglycaemic risk (short and long term) and special events (meals, physical activities, calibration) to provide an optimal recommendation adapted to the needs of the patient.
