Airway Clearance Units, Positive Expiratory Pressure, Oscillatory
Definition : Airway clearance units designed to apply forces at the airway opening to perform a simultaneous delivery of positive expiratory pressure and a high-frequency oscillation (HFO) of the air column in the conducting airways. These devices use one of several different techniques to create the airflow oscillation, including metallic ball vibrations and a combination of a counterweighted plug and a magnet. Oscillatory positive expiratory pressure units are used for prevention of early airway closure by stabilization of the airways with positive expiratory pressure (PEP) and to aid in mucus mobilization and expectoration in patients suffering from chronic obstructive pulmonary diseases.
