Abstract
A patient ventilation interface has a throat body defining a venturi throat that is open to ambient air, a nasal pillow disposed around the venturi throat to define a plenum between the venturi throat and the nasal pillow, a jet nozzle arranged to output ventilation gas into the venturi throat, and a pressure sensing tube having a pressure sensing port positioned to be in fluid communication with the plenum. The nasal pillow may be an integral part of the throat body. An expected error in the sensed patient airway pressure Pmay be corrected by applying a correction factor Pindexed by the sensed patient airway pressure Pand a jet nozzle flow V'of the jet nozzle. Delivery of the ventilation gas output by the jet nozzle may be controlled in response to the corrected patient airway pressure.
