Pressure support improves oxygenation and lung protection compared to pressure-controlled ventilation and is further improved by random variation of pressure support*

Abstract

In this model of acute lung injury, pressure support ventilation and noisy pressure support ventilation attenuated pulmonary inflammatory response and improved gas exchange as compared to pressure-controlled ventilation. Noisy pressure support ventilation further improved gas exchange, reduced the inspiratory effort, and attenuated alveolar edema and inflammatory infiltration as compared to conventional pressure support ventilation.
