Which ventilator adjustment should be considered in an infant with pulmonary hemorrhage?

• A. Decrease peak inspiratory pressure (PIP)
• B. Increase inspiratory time
• C. Increase FiO2
• D. Increase positive end-expiratory pressure (PEEP)

Answer: (D)

When an infant has pulmonary hemorrhage, the goal of ventilator management is to stabilize the alveoli, reduce ongoing bleeding, and improve oxygenation. Increasing PEEP raises the mean airway pressure, which helps keep alveoli open, improves oxygenation by reducing intrapulmonary shunt, and physically tamponades the bleeding by applying pressure in the airways and alveolar spaces. This approach directly addresses the bleeding source while supporting gas exchange.

Lowering peak inspiratory pressure might reduce the risk of barotrauma but can compromise lung recruitment and oxygenation, making bleeding harder to control. Extending inspiratory time or increasing FiO2 alone don’t address the bleeding mechanism as effectively; they may help with oxygenation but won’t provide the same benefit in stabilizing the bleeding as increasing PEEP. Monitor carefully for hemodynamic effects and potential air leaks, as higher PEEP can impact preload and cause pneumothorax in fragile neonates.
