t:slim X2 with Control-IQ

t:slim X2 insulin with Control-IQ Technology from Tandem Diabetes Care

The t:slim® X2 insulin pump with Control-IQ technology is an advanced hybrid closed-loop system that uses an algorithm to automatically adjust insulin delivery in response to glucose levels. The system predicts glucose values 30 minutes ahead, based on CGM readings, and can decrease or stop basal insulin delivery to help prevent lows, or increase basal insulin delivery and deliver correction boluses to help avoid highs.
