    Description BIPAP (optional) Biphasic Positive Airway Pressure The BIPAP ventilation mode is a pressure-controlled/time- cycled ventilation mode in which the patient can always breathe spontaneously. BIPAP is therefore often described as a timed alternation between two CPAP levels. The time-cycled change of pressure produces controlled ventilation corresponding to the pressure-controlled ventilation PCV.
