Abstract
A variable throat jet venturi for delivering ventilation gas to a patient includes a jet nozzle, a deformable throat body arranged to receive ventilation gas output by the jet nozzle and defining a gas inlet and a gas outlet, and a housing containing the deformable throat body. The housing may define an entrainment opening which is open to ambient air and a pilot pressure port for pressurizing a plenum between an outer wall of the deformable throat body and an inner wall of the housing. A pilot pressure line may be fluidly coupled to the pilot pressure port. A controller may be programmed to energize the pilot pressure line to constrict the deformable throat body during an exhalation phase of positive end-expiratory pressure (PEEP) therapy.
