BiWaze Airway Clearance Cough System

How BiWaze® Cough works

BiWaze® Cough is the respiratory therapy system that combines multiple therapies of assisted cough and lung expansion along with high frequency oscillation, BiWaze Cough breaks up and then removes mucus from the lungs by applying positive air pressure (inhale) to the airway and then rapidly shifting to negative air pressure (exhale). 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 so the person’s airways are stinted open after the exhale instead of being forcefully reopened with the next inhale.

Features

Oscillations
The Oscillation therapy feature delivers an oscillatory therapy based on frequency and amplitude settings. Use of the oscillation feature enhances mobilization and improves bronchial drainage.

Inspiratory Trigger
An important characteristic of the device is its ability to trigger on the patient’s inspiration to help synchronize the therapy with the patient. The inspiratory trigger feature is available when the device is in Auto mode. The pressure delivery sequence is synchronized with the patient’s effort to inhale.

Inspiratory Flow
While the expiratory switching is desired to be fast and at high flow to simulate cough, the inspiratory flow may be controlled to a comfortable level by selecting the flow between low, medium and high.

Positive Airway Pressure on the Pause Phase
Provides the option to keep airways open in-between the exhalation and inhalation phases of the cycle cough. This feature is designed to make the therapy more comfortable for the patient.
