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
