Lung ventilation strategies and regional lung inflammation

Abstract

Protective mechanical ventilation is currently accepted as a key strategy for the management of acute lung injury (ALI) and its most severe form, acute respiratory distress syndrome. The study by de Prost and colleagues in the current issue of Critical Care provides new insights into the impact of ventilation strategies on pulmonary function, gas exchange, and regional cellular metabolic activity during early ALI in sheep. The group reports that a protective ventilation strategy may attenuate neutrophil activation in dependent lung regions during early experimental ALI. This is an innovative report that provides the basis for further study. © 2013 BioMed Central Ltd.
