Comparison of airway pressure release ventilation (APRV) (blue curve) and biphasic positive airway pressure (BIPAP) (black curve). Comparison of airway pressure release ventilation (APRV) (blue curve) and biphasic positive airway pressure (BIPAP) (black curve). Compared to APRV, BIPAP uses shorter T high, longer T low, and usually higher P low. Despite the differences between their settings, mathematically both can achieve the same mean airway pressure (red line) and same tidal volume (green curve). Blue curves represent APRV, black curves represent BIPAP. Ehab G Daoud et al. Respir Care 2012;57:282-292 (c) 2012 by Daedalus Enterprises, Inc.
