PRVC
Also written as: PRVC — Pressure-Regulated Volume Control
Pressure-regulated volume control ventilation that delivers a set tidal volume at the lowest possible pressure.
Full Definition
Pressure-regulated volume control (PRVC) is a dual-control ventilation mode that combines features of both pressure and volume ventilation. The ventilator delivers a preset tidal volume while automatically adjusting the inspiratory pressure to achieve that volume using the lowest possible pressure. This mode adapts to changes in lung compliance and airway resistance by modifying pressure delivery while maintaining consistent tidal volume delivery. PRVC is designed to provide the lung-protective benefits of pressure ventilation while ensuring reliable volume delivery, making it useful for patients with changing respiratory mechanics or those at risk for ventilator-induced lung injury.
Usage
Usage note: Specify both target tidal volume and pressure limits when documenting PRVC settings.
