The AEROBIKA Oscillating Positive Expiratory Pressure (OPEP) Therapy System is a convenient, user-friendly device that provides clinicians and their patients with a means for reliable, drug-free, natural airway clearance. The AEROBIKA OPEP system opens weak or collapsed airways by creating positive pressure and oscillations simultaneously, which helps move mucus to the upper airways where it can be coughed out. Clinical research has shown that use of the device improves the ability of a patient to bring up mucus, decreases cough frequency and breathlessness, and increases exercise tolerance, resulting in an enhanced quality of life.
