The setup for BIPAP using a mechanical ventilator

Bilevel positive airway pressure (BiPAP) is a proprietary name of Respironics, Inc. for continuous positive airway pressure (CPAP) with pressure support breaths. It is used during noninvasive positive pressure ventilation. It delivers a preset inspiratory positive airway pressure (IPAP) during inspiration and expiratory positive airway pressure (EPAP). BiPAP can be described as a continuous positive airway pressure system with a time-cycled or flow-cycled change of the applied pressure level.[1] CPAP, BPAP and other non-invasive ventilation modes have been shown to be effective management tools for chronic obstructive pulmonary disease, acute and chronic respiratory failure.[2] Another term for bilevel positive airway pressure, and the term becoming increasingly adopted by the medical community, is non-invasive positive pressure ventilation (NIPPV) or non-invasive ventilation (NIV).[3]

Use[edit]

Bilevel positive airway pressure is used when positive airway pressure is needed with the addition of pressure support. Common situations where positive airway pressure is indicated are those where taking a breath is difficult. These include pneumonia, chronic obstructive pulmonary disease, asthma and status asthmaticus.[4][5]

Settings and measurements[edit]

Terminology[edit]

The term "Bipap" can be confusing due to the existence of two almost identical terms being applied to two different modes:
