A PEP module (10) for producing and transmitting oscillations of expiratory air to the lungs and airways of a user to thereby loosen and mobilize mucus obstructions. The PEP module (10) includes an external device housing (20) having a mouthpiece (22) at a first end thereof and a cover (24) at an opposite second end thereof configured for providing resistance to the airflow of the expiratory air. The PEP module (10) further includes a valve assembly (30) contained within the external housing (20) and disposed medially between the mouthpiece (22) and the cover (24). The valve assembly (30) includes a valve housing (32) and a valve (40) moveably mounted on the valve housing (32). The valve (40) rapidly and repeatedly oscillates relative to the valve housing (32) as the user exhales to produce oscillations in the expiratory air that are transmitted to the lungs and airways of the user. |
