Abstract

A positive pressure airway device for providing resistance in an air pathway for a patient exhaling. The device includes a central tube region, a inspiratory air passageway for passing air into the central tube region when a patient breathing through the device inhales, and an expiratory air passageway for passing air out of the central tube region when a patient breathing through the device exhales, A valve in the expiratory air passageway allows air to flow out only when a patient using the device exhales with an expiratory air pressure greater than a selected pressure, and includes a stopper and a coil spring with an interior portion that is free from any structure that would prevent or significantly inhibit the "side-to-side" movement of the spring within the housing, and thus prevent or significantly inhibit providing a therapeutically-effective oscillating flow of air through the device. The stopper has a cone-shaped air-stopping surface providing a valve angle that may be different from the valve-seat angle so that either laminar or oscillating flow may be obtained.
