What type of breath does PRVC result in?

• A. Volume-limited, pressure-targeted mechanical breath
• B. Pressure-limited, volume-targeted mechanical breath
• C. Flow-controlled, pressure-limited breath
• D. Time-cycled, volume-controlled breath

Answer: (B)

Patient-activated ventilation control modes, such as Pressure Regulated Volume Control (PRVC), are designed to ensure that a set tidal volume is delivered to the patient while using pressure as the controlling factor. In PRVC, the ventilator adjusts the pressure based on the patient's lung mechanics to deliver the target tidal volume effectively. This allows for a dynamic and adaptive response to the patient's breathing efforts. When a patient initiates a breath, the ventilator first attempts to deliver a pressure sufficient to achieve the desired volume. If resistance or compliance changes occur, the system continuously monitors and adjusts the pressure to ensure that the targeted volume is met. This combination of pressure regulation and volume targeting offers both the safety of limiting pressure delivery and the efficiency of reaching a predetermined volume. Understanding this concept is crucial for clinicians, as it optimizes patient comfort while maintaining adequate ventilation and can be particularly beneficial for patients with varying respiratory conditions.
