The term Bipap is often source of confusion due to the existance of two almost identical terms used being applied to two different modes both in the late 1980's. The term Biphasic/bilevel ventilation was first used to describe a mode of ventilation consisting of alternating [[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). This is NOT the same as BiPAP (note small i) used by Respironics and others to denote their implementation of Non-Invasive pressure support.

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

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

  • IPAP: this is the pressure applied during patient triggered breaths.
  • EPAP: this is the pressure applied in between patient triggered breaths. It could also be considered a continuous positive pressure.
  • FiO2: The fraction of O2 percentage that is being added to the delivered air.
  • Vf: on many machines a respiratory rate is set as a guarantee for intermittent bursts of IPAP.

Terminology

The term Bipap is often source of confusion due to the existance of two almost identical terms used being applied to two different modes both in the late 1980's. The term Biphasic/bilevel ventilation was first used to describe a mode of ventilation consisting of alternating 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). This is NOT the same as BiPAP (note small i) used by Respironics and others to denote their implementation of Non-Invasive pressure support.
