What are essential settings adjusted in proportional assist ventilation?

• A. HR, PEEP, and inspiratory flow rate
• B. PEEP, FiO2, and sensitivity
• C. Tidal volume, inspiratory time, and pressure
• D. RR, I:E ratio, and flow rate

Answer: (B)

In proportional assist ventilation (PAV), the essential settings typically adjusted focus on optimizing the patient's ability to breathe while receiving assistance from the ventilator. One of the key settings is PEEP (Positive End-Expiratory Pressure), which helps to keep the alveoli open at the end of expiration, improving gas exchange and oxygenation. FiO2 (Fraction of Inspired Oxygen) is also critical as it ensures that the patient receives the necessary concentration of oxygen to meet their respiratory needs, particularly if there are issues with oxygenation. Sensitivity settings determine how easily the ventilator responds to the patient's efforts to take a breath, allowing for a more natural and responsive breathing experience. The combination of these factors makes PEEP, FiO2, and sensitivity integral to the function of proportional assist ventilation, as they directly influence both the support provided and the patient's own respiratory mechanics. Proper adjustment of these settings can lead to improved patient comfort and effectiveness of ventilation.
