1. A portable infusion system, comprising:
- a delivery mechanism adapted to facilitate delivery of a medicament to a user;
a memory adapted to store parameters relating to the delivery of the medicament;
a communications device adapted to receive information from a continuous glucose monitor;
a processor functionally linked to the delivery mechanism, the memory and the communications device, the processor configured to;
obtain the information from the continuous glucose monitor;
store in a memory a threshold relating to predicted accuracy of the continuous glucose monitor after which automatic adjustment of the delivery of the medicament based on the information from the continuous glucose monitor is not permitted;
monitor the information received from the continuous glucose monitor;
determine that the threshold has been reached;
disable automatic adjustment of the delivery of the medicament based on the information from the continuous glucose monitor if it is determined that the threshold has been reached.

Abstract
A portable infusion pump can communicate with glucose monitor, such as a continuous glucose monitor (CGM), to receive continuous feedback relating to a user'"'"'s blood glucose level during insulin or other medicament therapy and can automatically deliver insulin to a user when the CGM data indicates a need for additional insulin. Due to potential unreliability in the correlation of the CGM data to the user'"'"'s actual blood glucose level, risk mitigation can be employed to limit the amount of extra insulin that can be delivered by the pump in response to the CGM data.
