Smart Tech CGM Helps Manage Type 1 Diabetes
A closed-loop system (also known as an artificial pancreas), in which an insulin pump and continuous glucose monitor (CGM) interact to completely automate glucose management, is a technology goal for managing type 1 diabetes. Some current systems partially do that by suspending insulin delivery when glucose is heading low or automatically adjusting basal insulin delivery based on sensor readings. Tandem Diabetes Care’s T:slim X2 Insulin Pump With Control-IQ Technology takes it one step further, adding automatic delivery of a correction bolus when glucose rises too high. In a study, the system increased the amount of time participants spent with blood glucose levels between 70 and 180 mg/dl by 2.6 hours per day, for up to six months, compared with a pump and CGM that didn’t interact. In addition, the average percentage of time spent with blood glucose levels below 70 mg/dl was cut in half, from 2.25 to just 1.6 percent. While the device isn’t a closed-loop system (users still have to manually bolus for meals), it’s a step closer to a fully automated artificial pancreas.
