BiWaze Cough - User Reference Manual

1 Introduction
The BiWaze™ Cough device helps to clear bronchopulmonary secretions from the
respiratory system by providing a therapy which mimics a cough. The therapy consists of
three phases which mimic a cough; inhale, exhale, and pause phase.
The inhale phase is positive airway pressure to expand the lungs. Then exhale phase is a
sudden shift to negative pressure to pull the air out of lungs. Finally, the pause phase
provides positive pressure which keeps the airways open in between the inhale and exhale
phases.

1.1 Intended Use
This product is used for assisting patients to clear retained bronchopulmonary secretions
by gradually applying positive pressure to the airway, then rapidly shifting to a negative
pressure. This rapid shift in pressure, via a facemask, mouthpiece, endotracheal or
tracheostomy tube produces a high expiratory flow rate from the lungs, simulating a
cough
This device is designed for use on patients unable to cough or clear secretions effectively
due to reduced peak cough expiratory flow, resulting from high spinal cord injuries,
