1. A positive respiratory pressure apparatus comprising:
- a patient respiratory system interface;
a one-way valve positionable in the patient respiratory interface and configured to pass a fluid traveling in a predetermined direction from a first side to a second side of the one-way valve; and
wherein the patient respiratory system interface comprises a bypass window integral with, and defined by, the patient respiratory interface, the bypass window positioned adjacent the one-way valve, and wherein the patient respiratory interface further comprises a window opening adjustment mechanism movably disposed in the patient respiratory system interface and operable to change a size of an opening between the patient respiratory system interface and ambient air outside of the patient respiratory system interface, whereby the bypass window and window opening adjustment mechanism cooperate to selectively create one of a plurality of fluid resistances.
