What effect does an increase in peak airway pressure usually indicate during mechanical ventilation?

• A. Improved compliance of the lungs.
• B. Increased resistance in the airways.
• C. Decreased tidal volume delivery.
• D. Improved tidal volume delivery.

Answer: (B)

An increase in peak airway pressure during mechanical ventilation typically signifies increased resistance in the airways. This condition can occur due to various factors, such as bronchospasm, secretions obstructing the airways, or mechanical issues with the ventilatory circuit or equipment. When resistance within the airways rises, the ventilator must exert more pressure to deliver the same volume of air, leading to higher peak airway pressures. Monitoring these pressures is essential, as sustained increases can indicate potential complications that may require immediate intervention, such as suctioning of secretions or evaluating for possible endotracheal tube obstructions. Understanding this concept is crucial since it informs the clinician about the dynamics of patient ventilation and the need for potential adjustments in the supportive measures taken or the ventilator settings applied.
