Abstract
The method and system for controlling airway pressure in a ventilator during the inspiratory cycle involves controlling the flow of breathing gas through a flow supply valve venting the breathing gas at a desired rate of outflow through a relief valve to achieve the desired airway pressure. Measurements of the rates of actual supply flow, the actual outflow through the exhalation/relief valve, and the pressure in the airway are compared with desired values for determination the amount of error for feedback control of the ventilator system.
