Pressure Regulated Volume Control (PRVC)

  • PRVC is a mode of mechanical ventilation that combines both volume and pressure control modes
  • The main advantage to PRVC is that the tidal volume / minute ventilation is guaranteed while controlling airway pressures, thereby reducing the risk of ventilator induced lung injury
  • In PRVC, the ventilator delivers a pressure-controlled breath, but tidal volume is the key setting
  • The ventilator will automatically adjust inspiratory pressures until the desired TV is achieved
  • When using PRVC you need to set: target TV, RR, peak pressure alarm, inspiratory time, FiO2, and PEEP
