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
