How Closed Loop Systems Work

A closed loop system is composted of three integrated considents: a CGM, an insulin pump, and a control algorytm running on a decretated controller or smartphone app. The CGM continuously measures interstitial glucose levels andd transmits the data every 5- 15 minutes. Thee algorythm uses this data ta calculate thee exedid insulin dose and instructs the pump to deliver it.
