摘要：
A positive exhalation pressure device to increase the pressure gradient in the airways through the use of a valve housing coupled to a mouthpiece and having a flow passageway communicating between the ambient environment and the oral cavity, and a valve disposed in the housing, wherein the valve is moveable between first and second positions during inhalation and exhalation respectively, wherein the flow passageway is more restricted during exhalation than during inhalation.
