Volume Control Ventilation (VCV), has been the traditional controlled ventilation mode in anesthesia. In VCV, the ventilator delivers the preset tidal volume (TV) with a constant flow during the preset inspiratory time (Ti) at the preset respiratory rate.

What is volume control in ventilator?

Volume control ventilation defines the volume administered to the patient (tidal volume Vt as the control variable).

When do we use PCV?

PCV has been most commonly used in patients, such as those with ARDS, who have significantly reduced lung compliance characterized by high ventilating pressures and worsening hypoxemia despite a high fraction of inspired oxygen (Fio2) and level of PEEP.
