  • SYSTEM AND METHOD FOR ADAPTIVE HIGH FREQUENCY FLOW INTERRUPTER CONTROL IN A PATIENT RESPIRATORY VENTILATOR
    Publication number: 20160022934
    Abstract: A method and system for controlling fluid flow settings by receiving a precondition pressure wave function, representative of a precondition frequency, a precondition amplitude and a precondition pressure of the fluid flow in the system, establishing an operating pressure wave function, representative of an operating frequency, an operating amplitude and an operating pressure of the fluid flow desired in the system, determining cycle error between the precondition pressure wave function and the operating pressure wave function, converting the cycle error to flow adjustment, and updating an operating flow with the flow adjustment.
