BiWaze® Clear

Innovative Oscillating Lung Expansion (OLE) with a dual blower system to deliver consistent and accurate pressure and exclusive expiratory flow bias to help mobilize secretion clearance.1

Why Choose BiWaze Clear?

BiWaze Clear is a versatile airway clearance system that delivers OLE therapy for patients with atelectasis and/or retained secretions in the lower airways. Whether in the hospital or at home, it’s designed to help patients breathe easier, recover faster, and maintain lung health. The exclusive dual blower design provides a closed-circuit therapy to improve high-frequency oscillation control1, consistent and precise pressure delivery1, superior aerosol deposition2, enhance mucus mobilization1, and less fugitive aerosols2.

Effective

Provides a stronger expiratory flow bias, 2 to 3x more than other OLE systems, optimizing mucus mobilization1

Provides 3–5x greater aerosol deposition than other OLE systems during PEP and HFO phases2

Delivers all three components of OLE therapy—PEP, HFO, and aerosol—in a single session

Precision

Consistent and Accurate Oscillation Pressure1

Closed circuit design reduces aerosol loss and prevents pressure leaks

Consistently achieves expiratory flow bias across pediatric and adult models with normal, obstructive, and restrictive mechanics

Adaptable

Approved for use with mouthpiece, face mask, trach adapter, or in-line with ventilators

Lightweight 9 lb system with internal battery supports up to 10 therapies per charge

Transition-ready for hospital-to-home use with intuitive touchscreen interface

How does BiWaze® Clear Work?

The BiWaze® Clear System delivers oscillating lung expansion (OLE) therapy to help treat and prevent atelectasis, mobilize retained secretions from deep within the lungs, and reduce the work of breathing.

The system provides three integrated respiratory therapies:

  • Positive Expiratory Pressure (PEP): Delivers programmed positive pressure that the patient exhales against, opening and expanding the airways. The nebulizer can operate during PEP therapy to distribute saline solution throughout the airways.
  • High-Frequency Oscillation (HFO): Generates programmed pulses of positive pressure to thin secretions and move them from the distal airways to the upper airways, where they can be coughed out or suctioned. The nebulizer can also run during HFO therapy for enhanced saline distribution.
  • Nebulizer (NEB): Powers the integrated Aerogen® Solo vibrating mesh nebulizer to deliver aerosolized saline or medications directly to the lungs.
Alternating between PEP and HFO every 2.5 minutes while continuously delivering NEB therapy, the system completes a full OLE therapy session in just 10 minutes.

Innovative Design for Advancing Airway Clearance

Dual blowers in BiWaze Clear provide the ability to control the inhale and exhale paths through the Dual Lumen breathing circuit.

The closed circuit design reduces fugitive aerosols by directing the exhale through the coaxial filter and the Aeorgen® Solo nebulizer* ensures a high respirable dose for the patient.

Oscillating Lung Expansion (OLE) therapy is a proven option to reduce PPCs for your at risk patients after thoracic, upper abdomen, trauma, burns, geriatric or splinting.3

The therapy can be delivered through a mouthpiece, face mask or trach adapter to pediatric or adult patients.  

Electronic blower design allows therapy to be available in any area of the hospital like the ICU, ED, and other step-down wards and long-term care facilities.

A battery is included with every system for flexibility and use across the continuum of care outside the hospital like rehabilitation or home care.
