BiWaze® Cough delivers mechanical insufflation/exsufflation (MIE) therapy by breaking up and removing mucus from the lungs by applying positive air pressure (inhalation) to the airway and then rapidly shifting to negative air pressure (exhalation).

After the exhalation phase of the cough cycle, 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, so the person’s airways are stinted open after the exhale instead of being forcefully reopened with the next inhale.

BiWaze Cough was inspired by people who need airway clearance treatments tailored to their changing respiratory needs. The dual airpath control separates the inhalation and exhalation airflow to help ensure the inhaled air is not contaminated with mucus from the exhaled air. The low-profile design and simplified touchscreen navigation make BiWaze Cough easy to use. The system provides a non-invasive solution to enhance airway clearance is essential to avoid retained mucus that causes infection, inflammation, and respiratory failure. Each therapy cycle can be personalized to provide the most effective therapy for a person’s respiratory condition.
