Conventional ventilation modes with small pressure amplitudes and high positive end-expiratory pressure levels optimize surfactant therapy.


OBJECTIVE High-frequency oscillation studies have shown that ventilation at high end-expiratory lung volumes combined with small volume cycles at high rates best preserves exogenous surfactant and gas exchange in lavaged lungs. We investigated whether surfactant composition and gas exchange can also be preserved by conventional modes of mechanical… (More)
