What is Pressure Regulated Volume Control (PRVC) considered?

• A. A purely pressure-controlled mode
• B. A pure volume-controlled mode
• C. A dual controlled mode
• D. A spontaneous mode

Answer: (C)

Pressure Regulated Volume Control (PRVC) is considered a dual controlled mode because it combines characteristics of both pressure control and volume control. In PRVC, the ventilator ensures that a preset tidal volume is delivered while regulating the pressure to maintain patient safety and comfort. This means that the ventilator can adjust the pressure it applies on a breath-by-breath basis to achieve the target tidal volume, allowing for flexibility in varying patient compliance and resistance conditions. This capability is particularly beneficial because it helps optimize ventilation by delivering adequate volumes while preventing excessive airway pressures that can occur in purely pressure-controlled modes. In essence, PRVC allows for a balance between volume delivery and pressure safety, making it adaptable to a range of patient needs and lung mechanics.
