Control-IQ™ technology is an advanced hybrid closed loop system, used with continuous glucose monitoring (CGM) it automatically adjusts the insulin dose based on the sensor data, and manages automatic correction bolus and suspensions if necessary. The system calculates the glucose value 30 minutes in the future and adjust the insulin dose ​​accordingly: If the prediction is located between 6.25 mmol/L and 8.9 mmol/L the pump maintains the basal rate programmed in the personal profile. If the prediction is located below 6.25 mmol/L programmed basal rate decreases. - If the prediction is below 3.9 mmol/L the pump suspends the supply of insulin. If the prediction is above 8.9 mmol/L the programmed basal rate increases. If the prediction is above 10.0 mmol/L the pump provides an automatic correction bolus. The system has a Sleep activity that sets a target between a narrower range of 6.25 mmol/L and 6.7 mmol/L; there is also an Exercise activity which increases the target range between 7.8 and 8.9 mmol/L to minimise hypoglycaemia. If glucose alerts and CGM readings do not match your symptoms or expectations, use a blood glucose meter for making diabetes management decisions. You can read more about Control-IQ™ technology here.
