What does PRVC stand for?

• A. Pressure Rise Variable Control
• B. Proportional Rate Variable Control
• C. Pressure Regulated Volume Control
• D. Proportional Regulation Volume Control

Answer: (C)

PRVC stands for Pressure Regulated Volume Control. This mode of mechanical ventilation is designed to deliver a targeted tidal volume while managing airway pressures. In PRVC, the ventilator adjusts the pressure applied to achieve the desired volume without exceeding preset pressure limits. This helps to ensure adequate ventilation while minimizing the risk of barotrauma or volutrauma to the lungs by preventing excessively high pressures. It is particularly useful in patients with varying compliance and resistance, allowing for adaptability in the ventilatory strategy.

The other options do not correctly define PRVC. For instance, Pressure Rise Variable Control, Proportional Rate Variable Control, and Proportional Regulation Volume Control do not encompass the essential characteristics of this ventilation mode, specifically its focus on regulating volume based on pressure parameters.
