BiWaze® Clear
BiWaze® Clear is a respiratory medical device designed to address secretion retention in the airways. This condition poses a significant health risk for patients with chronic respiratory diseases. Without proper treatment, breathing becomes increasingly difficult, and the likelihood of acute and chronic infections rises.

BiWaze
Three treatment options in one device
BiWaze® Clear combines three essential therapies for effectively treating secretion retention.
- PEP therapy recruits the airways by applying positive pressure during both inhalation and exhalation. This increases resistance during exhalation, helping to open and stabilise the airways.
- The goal of oscillation therapy is to loosen mucus within the airways, facilitating its removal. With two turbines, the oscillation is powerful enough to reach even deeper secretions.
- Additionally, an integrated Aerogen Solo Mesh nebuliser allows for direct medication administration through the device's tubing. This medication not only helps treat secretions but can also dilate the airways and improve the consistency of mucus for easier removal.

Unique selling point

BiWaze® Clear works and saves time
By combining several treatment options in one device, BiWaze® Clear saves important time. A therapy session does not have to last longer than 10 minutes. This can be compared to the 30 minutes of conventional HFCWO (High Frequency Chest Wall Oscillation) therapy with a significant time saving.
Aerosol therapy

Excellent aerosol deposition
An in-vitro study showed that BiWaze® Clear delivers higher aerosol deposition in the lungs compared to the Volara system. The closed, double-lumen ventilation circuit with the Aerogen nebuliser has a significant impact on aerosol delivery.¹
5x more aerosol during PEP therapy¹
3x more aerosol during OSC therapy¹
2x less volatile aerosol¹

Therapy effectiveness

Reduction of postoperative pulmonary complications with OLE therapy
Research shows that OLE therapy reduces the rate of postoperative pulmonary complications (PPCs) in high-risk patients as classified by the American Society of Anesthesiologists (ASA). PPCs can lead to morbidity, mortality and healthcare expenditure.¹
Postoperative pulmonary complications:
31% from 22.9% to 15.8% (all patients)
Reduction in length of stay (days):
1.6% hospital days

Advanced technology in a sleek design
Complementing its user-friendly design, BiWaze® Clear provides a wide range of settings that can be tailored to the specific needs of users. The device is suitable for both home and hospital use, with mobility being a crucial factor in its usability. To enhance portability, BiWaze® Clear is equipped with a rechargeable battery that allows for up to 10 treatment cycles without needing to be plugged in. Weighing just 4.1 kg, it is light and easy to move around at home or on the ward.
Like the BiWaze® Cough device, BiWaze® Clear features two separate turbines. This separation of respiratory flows minimizes the risk of inhaling contaminated air and allows for the quicker and more effective removal of loosened secretions. This self-contained system not only serves as a unique selling point but also enhances hygienic protection and reduces risks associated with dead space.
