vol·ume-con·trolled ven·ti·la·tion

(vol'yūm-kŏn-trōld' ven'ti-lā'shŭn)
A mode of mechanical ventilation in which the ventilator delivers a preset volume waveform; the resultant airway pressure waveform depends on the shape of the flow waveform and respiratory system resistance and compliance.

volume-controlled ventilation

A form of mechanical ventilation in which the peak inspiratory flow rate, fraction of inspired oxygen, positive end-expiratory pressure, respiratory rate, and tidal volume are preset and delivered to the patient.
Synonym: volume-cycled ventilation; volume-limited ventilation

Six patients (24%) in the CV group showed peak inspiratory pressure >30 cm[H.sub.2]O, so the volume-controlled ventilation mode was changed to a pressure-controlled mode to achieve a targeted [V.sub.T] according to our study protocol.
