Which of the following is considered a disadvantage of PRVC?

• A. Decreased ability to deliver ventilation
• B. Increased patient demand leads to decreased support
• C. Pressure increases lead to mechanical failure
• D. Requires constant monitoring

Answer: (B)

In the context of PRVC (Pressure Regulated Volume Control) ventilation, increased patient demand leading to decreased support is indeed a notable disadvantage. PRVC is designed to deliver a predetermined tidal volume while automatically adjusting the pressure support based on the patient's lung mechanics and compliance. However, during periods of increased demand, a patient's inspiratory efforts may increase, which can lead to insufficient assistance from the ventilator. As the patient's need for ventilation rises, the mode may not be able to provide adequate support, resulting in inadequate ventilation or potential respiratory distress. This characteristic makes it crucial for healthcare providers to closely monitor patients on PRVC, particularly when their respiratory needs fluctuate. In addition, the dynamic nature of such scenarios can sometimes complicate the overall management of ventilation, as maintaining a balance between patient effort and ventilator support can be challenging. Understanding this aspect of PRVC is essential, especially when evaluating its efficacy in different clinical situations where patient demand can rapidly change. It emphasizes the importance of tailoring ventilator settings and maintaining a vigilant approach to monitoring patients on this mode of ventilation.
