A Novel Approach Using Volumetric Dynamic Airway CT to Determine Optimal Positive End Expiratory Pressure (PEEP) Settings in Neonates Requiring Long-Term Ventilator Support

Positive End Expiratory Pressure PEEP is a key mechanical ventilator setting in neonates with bronchopulmonary dysplasia BPD. Excessive PEEP may result in insufficient CO2 elimination and lung damage, while insufficient PEEP can result in impaired gas exchange secondary to airway and alveolar collapse. Determining PEEP settings based on clinical parameters alone is suboptimal due to the inability to titrate pressure with airway dimensions. The purpose of this study is to describe our experience using dynamic airway CT to determine the lowest PEEP setting sufficient to maintain airway patency in BPD patients requiring long-term ventilator support.
