It’s the new sound of the Vibralung® Acoustical Percussor, and it’s starting a revolution in Airway Clearance Therapy (ACT) for patients with mucus-producing lung disease and difficulty in clearing secretions. The Vibralung Acoustical Percussor applies vibratory sound waves, during inspiration and exhalation, over a wide range of frequencies (~5 to 1,200 Hz) to vibrate the column of gas in the tracheobronchial tract. As a result, mucus is loosened and separated throughout the airways, by the principle of sympathetic resonance, to promote safe, effective and gentle ACT like no other alternative.
