Basal-IQ® technology helps reduce the frequency and duration of hypoglycaemia. Used together with a continuous glucose monitor (CGM) - The system predicts the glucose level 30 minutes in the future and suspends insulin delivery when a fall in blood glucose levels below 4.4 mmol/L is expected. Or suspends on a real time reading of 3.9 mmol/L -The insulin delivery resumes when glucose levels of the sensor starts to rise again. If glucose alerts and CGM readings do not match your symptoms or expectations, use a blood glucose meter for diabetes management decisions. You can read more about Basal-IQ® here.
