Pressure-regulated volume control is an IMV based mode. Pressure-regulated volume control utilizes pressure-limited, volume-targeted, time-cycled breaths that can be either ventilator- or patient-initiated.

The peak inspiratory pressure delivered by the transport ventilator is varied on a breath-to-breath basis to achieve a target tidal volume that is set by the clinician.

 

For example, if a target tidal volume of 500 mL is set but the transport ventilator delivers 600 mL, the next breath will be delivered with a lower inspiratory pressure to achieve a lower tidal volume. Though PRVC is regarded as a hybrid mode because of its tidal-volume (VC) settings and pressure-limiting (PC) settings fundamentally PRVC is a volume-control mode.
