We appreciate Drs. Dunning and Woehlck’s arguments regarding our paper. It is true that many confounding factors, including Fio 2, rebreathing, and alveolar ventilation, might affect our observations.

Preterm birth and respiratory support with invasive mechanical ventilation frequently leads to bronchopulmonary dysplasia (BPD). A hallmark feature of BPD is alveolar simplification. For our preterm.

Applying PEEP increases alveolar pressure and alveolar volume. This splinting, or propping open, of the alveoli with positive pressure improves the ventilation-perfusion match, reducing the shunt.
