Abstract
Systems and methods for providing a breathing gas are provided. In one embodiment, the method includes sensing a sensed parameter associated with delivery of the breathing gas, changing a control parameter associated with a flow/pressure control element in response to a difference between the sensed parameter and a first predetermined sensed parameter value during a first portion of a breathing cycle, determining a transition from the first portion to a second portion of the breathing cycle based at least in part on the changing control parameter, changing the control parameter to cause a first change in the sensed parameter during the second portion of the breathing cycle based at least in part on the determined transition, and changing the control parameter to cause a second change in the sensed parameter during a third portion of the breathing cycle based at least in part on the first predetermined sensed parameter value.
