What does PRVC stand for in ventilation modes?

• A. Pressure Regulated Volume Control
• B. Positive Rate Ventilation Control
• C. Precise Respiratory Volume Calibration
• D. Pressure Residual Volume Control

Answer: (A)

PRVC stands for Pressure Regulated Volume Control, which is a mode of mechanical ventilation that combines features of volume-controlled and pressure-controlled ventilation. In this mode, a preset tidal volume is targeted while limiting the peak inspiratory pressure. The ventilator adjusts the airway pressure during inspiration to ensure that the patient receives the desired tidal volume. If the lung compliance decreases or the airway resistance increases, the ventilator will automatically adjust the pressure to meet the volume goal, thus optimizing patient comfort while minimizing the risk of barotrauma or volutrauma. This adaptability makes PRVC suitable for patients with varying respiratory mechanics, allowing for flexible ventilation strategies based on their needs. Understanding this mode is crucial for optimizing ventilation in patients with conditions such as acute respiratory distress syndrome (ARDS) where lung mechanics can fluctuate significantly.
