What is a key advantage of using PRVC mode?

• A. Increased respiratory rate
• B. Guaranteed minute ventilation
• C. Lower oxygen demand
• D. Reduced pressure on the lungs

Answer: (B)

The key advantage of using PRVC (Pressure Regulated Volume Control) mode lies in its ability to guarantee minute ventilation. This mode combines features of both volume and pressure modes, allowing the ventilator to deliver a preset tidal volume while automatically adjusting the pressure required to achieve that volume based on the patient's lung compliance and resistance. This ensures that the patient receives an adequate volume of air (minute ventilation) regardless of changes in lung mechanics, which is particularly beneficial in patients with variable or compromised respiratory function. By maintaining the desired minute ventilation, PRVC helps prevent both hypoventilation and the risk of barotrauma, as it adapts the pressure delivered to accommodate the patient’s needs. This adaptability makes it an effective mode for managing patients who require assistance with ventilation while still ensuring they achieve sufficient gas exchange. It allows clinicians to provide more tailored respiratory support while protecting the patient's lungs from high pressures that can occur in fixed pressure modes.
