#$%^&*AU2017276328A120180118.pdf#####AIR DETECTION SYSTEM AND METHOD FOR DETECTING AIR IN A PUMP OF AN INFUSION SYSTEM ABSTRACT Various systems and methods for detecting air in a chamber of an infusion system are disclosed. In one embodiment, a determination is made that air is contained in the chamber on the basis of a change in the average force exerted against the plunger utilizing a derivative spike for event detection and a systematic reduction in the average force to confirm the nature of the change. In another embodiment, a determination is made that the chamber contains air when a difference between the current force profile and a baseline force profile crosses a threshold. In an additional embodiment, a force profile is classified as being an air force profile or a liquid force profile based on extracted features of the force profile.
