What is the maximum level for pressure in PRVC?

• A. It is not limited
• B. Set by the clinician only
• C. There is a maximum level above which it cannot rise
• D. It changes based on patient need

Answer: (C)

The statement that there is a maximum level above which pressure cannot rise in Pressure Regulated Volume Control (PRVC) mode reflects an essential aspect of this ventilatory strategy. In PRVC, the ventilator is designed to deliver a specific tidal volume while automatically adjusting the pressure to optimize patient comfort and minimize the risk of lung injury. This mode ensures that while the tidal volume is maintained, the pressure does not exceed a predefined limit set by the clinician. This cap on pressure is crucial for protecting the lungs, preventing barotrauma, and managing patient safety effectively. When the patient's lung compliance or resistance changes, the ventilator will adjust the pressure to maintain the target volume, but it will not surpass the maximum pressure level set. Thus, this safety feature is vital for patient management, ensuring that the ventilatory support provided is both effective and safe. Understanding this limit is important for clinicians to ensure that they are managing mechanical ventilation appropriately, especially in patients with varying conditions that may affect lung mechanics.
