AirPysio is indicated for use as a positive Expiratory Pressure(PEP) device for improving the clearance of mucus secretions from the airways. It vibrates the airway walls to assist in loosening mucus and intermittently increases endobronchial pressure so that airway patency can be maintained during exhalation, reducing the potential for mucus becoming trapped as it moves up the airways.
This device is highly recommended for lung health maintenance. It takes some practice to get the ball to oscillate, but using it in the sweet spot has a near-immediate effect on breathing. A handy thing to have been using around COVID, summer fires, etc.
The tool is not an innovation, but rather a clone of a traditional health maintenance tactic found in Asian cultures.
