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. 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. 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).
The term "Bipap" can be confusing due to the existence of two almost identical terms being applied to two different modes:
BIPAP The term "Biphasic/bilevel ventilation" was used to describe a mode of ventilation that alternates PEEP levels presented in 1988 by Professor Benzer of Innsbruck and his group. The term for this mode, as used by Dragear on their ventilators is "BIPAP" (note large "I").
BiPAP is used by Respironics and others to denote their implementation of non-invasive pressure support plus CPAP (note small "i").
