The setup for BPAP using a mechanical ventilator

Bilevel positive airway pressure (BPAP), commonly referred to by the trademarked names BiPAP and BIPAP, is a form of non-invasive mechanical pressure support ventilation that uses a time-cycled or flow-cycled change between two different applied levels of positive airway pressure.[1][2]

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, status asthmaticus, and late stage amyotrophic lateral sclerosis.[3][4]

BPAP is different from continuous positive airway pressure (CPAP), which applies a single level of positive airway pressure throughout the whole respiratory cycle and is used for different clinical conditions.[1]
