摘要：
The invention relates to a pressure responsive respiratory valve apparatus for enabling positive pressure from a source of pressure to be applied to a users airway, and allowing ingress of a breathable gas from an inlet port into a users airway during inhalation and egress of expired tidal volume of air from the users respiratory system to an exhalation port during exhalation. The invention minimises rebreathing of expired gas and optimizes delivery of pressurised breathable gas by venting gas only during exhalation, as well as addressing important user considerations including minimizing noise, pressure swing, and size.
