Cough assist · lung expansion · oscillation
The ABM BiWaze® Cough System helps people who can't cough effectively clear secretions from their lungs. MEC supplies it across Australia, with demonstrations, setup, training and ongoing consumables from our local team.
The BiWaze Cough System is a mechanical insufflation-exsufflation (MI-E) device, often called a cough assist. It gives the lungs a deep breath with positive pressure, then switches quickly to negative pressure to draw air, and mucus, back out, much like a strong natural cough.
BiWaze Cough adds high-frequency oscillation to help loosen secretions, and can hold positive pressure during the pause between coughs to help keep the airways open. Two separate blowers handle the inhale and exhale air paths, so exhaled air and secretions are kept apart from the air being breathed in.
It's used at home, in hospital and in residential care, through a face mask, mouthpiece or tracheostomy connection. As the exclusive Australian distributor, MEC supplies the device, its circuits and accessories, and the training to use it well.
Each cycle has up to four phases. The treating clinician sets the pressures, timing and oscillation for each patient.
Positive pressure fills the lungs with a deep breath (insufflation).
A fast shift to negative pressure draws air and secretions out, like a cough (exsufflation).
Optional positive pressure between cycles helps keep lung volume steady (PAP on pause).
High-frequency oscillation during the inhale, the exhale or both helps loosen and move mucus.
Separate inhale and exhale air paths for precise pressure and flow, and to keep exhaled secretions away from inhaled air.
Run therapy automatically from a stored profile, or cycle each breath manually.
Set up and adjust therapy on a colour touchscreen, with up to 10 profiles saved.
Up to two hours of use away from the power point, in a 4.1 kg unit.
Cough assist therapy is for people whose cough is too weak to clear secretions on its own, most often people with neuromuscular conditions such as motor neurone disease, muscular dystrophy or spinal muscular atrophy, spinal cord injury, or other conditions that weaken the breathing muscles.
