Regulation of insulin on board

Abstract

Disclosed herein are techniques related to regulation of insulin on board. In some examples, the techniques may involve obtaining a glucose measurement value generated from a sensing arrangement. The techniques may also involve determining that the glucose measurement value is a valid glucose measurement value. Furthermore, the techniques may involve maintaining a threshold amount of insulin on board (IOB) based on regulating insulin delivery. Maintaining the threshold amount of IOB may be performed responsive to the valid glucose measurement value being less than a threshold glucose value.
