airway pressure release ventilation

mechanical ventilation in which patients being treated with continuous positive airway pressure have intermittent decreases rather than increases in airway pressure and volume.

air·way pres·sure re·lease ven·ti·la·tion

(APRV) (ār'wā presh'ŭr rĕ-lēs' ven'ti-lā'shŭn)

A mode of mechanical ventilation.

airway pressure release ventilation

A type of mechanical ventilation in which patients breathe spontaneously at any phase of the ventilator's duty cycle at high continuous positive airway pressures (CPAP). Periodically, the level of CPAP is lowered to eliminate waste gases from the circuit.

Of these patients, three were ventilated using airway pressure release ventilation for which a PEEP of 0 cm[H.sub.2]O is recommended (16).

(d) One patient ventilated with airway pressure release ventilation for which PEEP set at 0 cm[H.sub.2]0 and prolonged inspiratory time are recommended (18).
