1. A Positive Expiratory Pressure (PEP) module comprising:

  • an airflow passageway formed from a device housing and a valve housing, the airflow passageway having a first end and an opposing second end; and

    a valve assembly configured to be disposed between the first and second airflow passageway ends, the valve assembly comprising the valve housing and a valve movably mounted on the valve housing, the valve defined by first and second legs movably affixed to the valve housing, the first and second legs joined by a central ledge, the central ledge defining an angle that is complementary to an angle defined by a wall that forms a portion of the airflow passageway, whereby the valve is operable for producing oscillations in an airflow, whereby the valve is configured to pivot between a first posture substantially in the airflow whereby the valve is positioned more proximal the airflow passageway and oriented complementary thereto, and a second posture substantially out of the airflow whereby the valve is pivoted more distal relative to the airflow passageway, and whereby the valve assumes the first posture absent the presence of the airflow.
