The BiWaze® Cough System is built to use a combination of high frequency oscillation, lung expansion and assisted cough therapy to break up mucus and clear airways. The dual air pathways separate inhale and exhale flows, helping ensure the inhaled air is not contaminated with mucus from the exhaled air.

After exhale, the pause phase allows the user to rest before the next assisted cough cycle. BiWaze Cough can provide positive pressure flow during the pause phase, creating a higher mean airway pressure which keeps the Functional Residual Capacity higher post exhale and provides a more comfortable therapy for the patient.
