Abstract
Disclosed herein are apparatuses and methods that account for meal announcements in closed loop insulin delivery systems. Rather than simply increasing an insulin delivery rate in response to the meal announcement, the closed loop algorithm can be modified to increase the insulin on board tolerance during eating periods. This approach utilizes the stability of the cascaded loop in the closed loop algorithm to prevent the oscillations in glucose levels that can occur by simply increasing the basal rate.
