## Indications for use
AirPhysio is indicated for use as a Positive Expiratory Pressure (PEP) Device for improving the clearance of mucus secretions from the airways. AirPhysio vibrates the airway walls to assist in loosening mucus and intermittently increases endobronchial pressure so that the airway patency can be maintained during exhalation, reducing the potential of mucus becoming trapped as it moves up the airways. The device may also be useful in the removal of mucus from patients who have chronic bronchitis or bronchiectasis and in conjunction with a medical need for positive expiratory pressure (PEP) therapy.
