In the PRVC mode, the ventilator delivers a volume-controlled breath. Using the plateau pressure from the previous delivered breath, the ventilator delivers the next breath. This allows the lowest delivery pressure, which is the target VT.

When should I use PRVC mode?

PRVC may be used for the adult, pediatric, and infant populations. If the patient’s lung compliance decreases or airway resistance increases, the system flow and pressure increases. If lung compliance increases or airway resistance decreases, the system flow and pressure decreases.

What mode of ventilation is PRVC?

PRVC is a controlled mode of ventilation which combines pressure and volume controlled ventilation. A preset tidal volume is delivered at a set rate, similar to VC, but it is delivered with the lowest possible pressure.
