What is the low glucose suspend feature on the minimedâ„¢ 640g?

Low glucose suspend feature^ (when used in conjunction with Continuous Glucose Monitoring (CGM)) is a feature to help if you want additional protection against hypoglycaemia or hypoglycaemia unawareness. If the feature is turned on, the pump automatically suspends insulin infusion for 2 hours when glucose levels reach a pre-determined threshold and, without intervention, will resume basal insulin delivery to its pre-set rate. All other sensor functions remain operational during insulin suspension.
