Claim 10:
11. An ambulatory infusion pump system, comprising:
a pump mechanism configured to facilitate delivery of insulin to a user;
a communications interface adapted to receive glucose levels from a continuous glucose monitor;
at least one processor functionally linked to the pump mechanism and the communications interface, the at least one processor configured to:
automatically calculate insulin doses with a closed loop delivery algorithm based on glucose levels received from the continuous glucose monitor, the closed loop delivery algorithm configured to calculate the insulin doses to maintain a user's glucose levels within a first target glucose range including a low glucose threshold and a high glucose threshold;
automatically deliver the insulin doses calculated by the closed loop delivery algorithm to the user with the pump mechanism;
determine that the first target glucose range should be modified from the first target glucose range to a second target glucose range;
determine an amount of time elapsed since a most recent bolus delivery of insulin has been delivered by the pump mechanism;
alter the first target glucose range to the second target glucose range if the amount of time since the most recent bolus delivery of insulin is greater than a predetermined amount of time from the determination to modify the first target glucose range.
