Gravity Predominates Over Ventilatory Pattern in the Prevention of Ventilator-Associated Pneumonia

Abstract

The Trendelenburg position predominates over expiratory flow bias and positive end-expiratory pressure in the prevention of gravity-dependent translocation of oropharyngeal pathogens and development of ventilator-associated pneumonia. These findings further substantiate the primary role of gravity in the pathogenesis of ventilator-associated pneumonia.
