Do conventional ventilation modes with small pressure amplitudes and high positive end-expiratory pressure levels optimize surfactant therapy?
We conclude that exogenous surfactant composition is preserved by conventional modes of mechanical ventilation that use small pressure amplitudes, and adequate oxygenation is maintained by high end-expiratory pressure levels. Effective carbon dioxide removal can be achieved by applying a ventilation mode that creates auto PEEP and not by a mode that applies the same level of PEEP by static PEEP only.
