The Acapella breathing device is a hand-held apparatus that clears the airways for easier breathing in patients with chronic lung conditions, explains National Jewish Health. The Acapella helps loosen the secretions and aids in the clearance of mucous blockages.
The device comprises a detachable mouthpiece, a lid and a unit at the base. When a person breathes out through the Acapella, the flow of air causes the rocker at the base to move in one direction, notes National Jewish Health. It moves back to its original place leading to a vibration and resistance to the airflow, which keep the airways open. Sputum is loosened and released by the vibrations, leading to more efficient clearance of the clogged airways.
