Biphasic positive airway pressure (BIPAP) and airway pressure release ventilation (APRV) are ventilator modes using biphasic continuous positive airway pressure (CPAP), which ventilate by time-cycled switching between two pressure levels with a high-low valve. This allows unrestricted spontaneous breathing in any phase of the ventilator cycle with a demand valve. High pressure levels are applied to improve oxygenation while the pressure is periodically released to low levels to assist ventilation. Since the definitions of BIPAP and APRV are indistinct and few studies of these two modes have been published, the potential benefits of these modes have not been realized. Recently, a definition of APRV was proposed by Habashi (PLow 0cmH2O, TLow=PEF 75%), which was used in several clinical studies. In 2017, a single-center randomized controlled trial was conducted, showing the efficacy of APRV in patients with ARDS. Further clinical studies are warranted to evaluate the efficacy and validity of these modes.
