Abstract: The disclosed invention provides a breathing circuit that includes a volume regulator that includes only three ports which include an inlet port connected to the exhalation port, a first outlet port connected to atmosphere, and a second outlet port connected to the moisturizer assembly. The breathing circuit is used for a ventilation system that delivers breaths to a patient. The inlet port of the volume regulator includes a flapper valve that moves only inward at an open position to receive the exhaled gas from the patient. The first outlet port includes a flapper valve that moves outward at an open position to exhaust gas in the volume regulator into the atmosphere. The second outlet port includes a flapper valve that moves only outward at an open position to exhaust gas in the volume regulator into the moisturizer assembly.

Abstract: Method and apparatus for providing percussive ventilation therapy to a patient airway preferably includes at least one driver unit configured to provide pressurized, non-pulsate gas. At least one patient interface device preferably has structure configured to (i) receive the pressurized, non-pulsate gas from the at least one driver unit and transform it into a pulsed and pressurized gas, and (ii) supply at least one sub tidal volume of pulsed and pressurized gas to a patient through a patient connection orifice. At least one flexible tube is preferably configured to provide pressurized, non-pulsate gas from the at least one driver unit to the at least one patient interface device. Preferably, at least one portion of the patient interface device is disposable, and another portion may be reusable. Preferably, the invention uses Adaptive Dynamic Subtidal Ventilation technology.
