Pressure Regulated Volume Control (PRVC)

Here are some basic pearls about PRVC Ventilation

  • Form of Assist Control (AC) ventilation: patient initiated or ventilator intiated
  • Constant pressure through inspiration
  • Decelerating inspiratory flow pattern
  • Ventilator adjusts pressure breath to breath based on patient’s airway resistance and compliance
  • Not recommended for asthma or COPD
  • Set: RR, tidal volume, upper pressure limit, oxygen level, I:E ratio (can start at 1:2), PEEP

Benefits: minimum PIP, guaranteed tidal volume, patient can trigger more breaths, improved oxygenation, breath by breath changes
