Airway pressure-release ventilation provides two levels of continuous positive airway pressure while allowing the patient to breathe spontaneously at both continuous positive airway pressure levels.The sine waveforms at both continuous positive airway pressure levels represent the spontaneous breathing of the patient.The higher continuous positive airway pressure level is usually held longer than the lower continuous positive airway pressure level-hence the term airway pressure release.
