AirPhysio is a drug-free handheld Oscillating Positive Expiratory OPEP device designed to assist in the clearance of secretions from the lungs. It assists in improving lung capacity by conditioning the lungs, helping to loosen mucus build-up and assisting to open up semi-closed airways.
When you exhale (breathe out) through the AirPhysio, your breath moves the steel ball inside. The AirPhysio device:
Vibrates the airways, which loosens the bond of mucus to the airway walls for mucus clearance;
Intermittently increases endobronchial pressure (positive pressure in the airways), which assists to maintain the clearing of the airways while a person exhales so that mucus does not become trapped as it moves up the air canal;
Accelerates expiratory airflow, which facilitates the upward movement of the mucus through the airways so that it can be more easily cleared. This combined action of vibration and pressure results in the mucus moving progressively up your airways until you can cough it out.
