Which complication can arise from a high mean airway pressure (MAP) during ventilation?

• A. Decreased lung compliance
• B. Risk of barotrauma
• C. Respiratory acidosis
• D. Increased tidal volume

Answer: (B)

High mean airway pressure (MAP) during mechanical ventilation can lead to an increased risk of barotrauma. Barotrauma occurs when there is an injury to the lungs caused by increased air pressure within the alveoli, which can happen when high pressures are applied during ventilation. When MAP is elevated, it can cause overdistension of the alveoli, resulting in ruptures or tears in the pulmonary tissue. This is particularly dangerous because it can lead to complications such as pneumothorax or air leaks into surrounding tissues, which can significantly impact a patient’s respiratory status. Hence, managing MAP appropriately is crucial to minimize the risk of such severe complications.
