Abstract
A respiration appliance (10), system (40), and method (62, 72, 86) for supporting the airway of a subject (12) as the subject (12) breaths. The flow of gas from the lungs of the subject (12) during exhalation is leveraged to provide support to the airway. In particular, a body (14) that encloses one or more external orifices of the subject (12) provides a resistance differential between inhaled gas flows and exhaled gas flows that supports the subject's airway.
