BiWaze® Cough System

The next generation of Cough Assist

BiWaze® Cough is an innovative cough assist that signifies a significant advancement in treating patients with diminished or absent cough, poised to become the gold standard in cough assist therapy. It integrates multiple therapy options to aid patients with diminished cough ability and mucus retention. Utilising effective oscillation, BiWaze® Cough loosens and transports mucus, facilitating the coughing process.

How the BiWaze® Cough Assist works

BiWaze® Cough is a respiratory therapy system that integrates multiple therapies to enhance coughing, promote lung expansion, and facilitate mucus removal. It utilises positive air pressure during inhalation and rapidly shifts to negative air pressure during exhalation to effectively break up and expel mucus from the lungs.

First dual blower system
in a Cough Assist

Two separate blowers fully distinguish inhalation from exhalation. A coaxial tube is employed to keep exhaled and expectorated air separate from fresh air during the inhalation phase.

Features

Double turbine control

The standout feature of the BiWaze® Cough Assist is its two separate turbines, which completely isolate the internal airflows of the device. This dual turbine control enables more precise adjustments, resulting in a more comfortable and effective therapy experience.

Another notable aspect of BiWaze® Cough is the adjustable pause phase with positive pressure that can be set between coughing cycles, enhancing the overall treatment process.

Unique selling point

Peak cough flow

The PCF (Peak Cough Flow) generated by the device is frequently used to evaluate both its effectiveness and patient acceptance. BiWaze® Cough features a flow curve that closely resembles the natural respiratory flow curve during coughing. The effective plateau control of the device maintains a preload, enhancing both comfort and therapy effectiveness. Instead of applying excessive flow during inspiration, the device stabilizes the flow on a plateau. Patients report that this controlled approach is much more comfortable, which helps improve compliance and, ultimately, the success of the therapy.

Pressure and flow waveforms

Pressure and flow waveforms

BiWaze® Cough delivers a plateau-shaped flow curve that enhances preload, leading to higher expiratory flows (PCF). Additionally, the device improves patient comfort by facilitating a more physiological inhalation process.

Innovative design and
wide range of applications

The user-friendly design and intuitive touchscreen navigation of the BiWaze® Cough make it the easiest-to-use aid in its category. The device effectively balances two key aspects: its straightforward usability promotes an efficient workflow, while its versatile settings allow for maximum personalisation of therapy. This capability enables tailored therapy cycles that cater to the individual needs of patients.

BiWaze® Cough is particularly beneficial for those with neuromuscular or chronic respiratory diseases, conditions that often lead to secretion retention in the airways. By using BiWaze® Cough regularly, these patients can maintain clear airways, enhancing lung function and potentially reducing complications.
