What is one advantage of pressure-control ventilation (PCV)?

• A. Prevents barotrauma to the lungs
• B. Enforces peak tidal volume delivery
• C. Increases compliance variability
• D. Increases the risk of over distention

Answer: (A)

One significant advantage of pressure-control ventilation (PCV) is its ability to prevent barotrauma to the lungs. In this mode, the ventilator delivers breaths at a preset pressure, allowing for controlled ventilation without exceeding the chosen limit. By capping the pressure, PCV minimizes the risk of generating excessively high tidal volumes during each breath, which is particularly beneficial for patients with compromised lung structure. This control over peak airway pressure is crucial in avoiding injuries associated with over-distention of the alveoli, where excess pressure can lead to pneumothorax or other types of lung trauma. Thus, in scenarios where maintaining lung protection is paramount, pressure-control ventilation effectively reduces the likelihood of barotrauma, making it a safer option in managing patients with conditions such as Acute Respiratory Distress Syndrome (ARDS) or other lung pathologies.
