1. An infusion pump, comprising:
a sensor configured to detect an error condition associated with operation of the infusion pump, wherein the error condition is one of detection of air, detection of an occlusion, or a failure of the sensor;
a pumping mechanism to deliver medicament through an infusion set and associated downstream tubing to a user; and
a processor operably coupled to the sensor and the pumping mechanism, the processor configured to:
receive an indication from the sensor of the error condition;
continue operating the pumping mechanism in a safe-delay mode to deliver a predetermined quantity of the medicament without correcting the error condition, the predetermined quantity being based at least in part on a characteristic of the infusion set.
