A respiration appliance, system, and method for supporting the airway of a subject as the subject breathes. The flow of gas from the lungs of the subject during exhalation is leveraged to provide support to the airway. In particular, a body that encloses one or more external orifices of the subject provides a resistance differential between inhaled gas flows and exhaled gas flows that supports the subject's airway.
