Oxygenation Response to a Recruitment Maneuver during Supine and Prone Positions in an Oleic Acid - Induced Lung Injury Model

摘要

Prone position and recruitment maneuvers (RM) are proposed as adjuncts to mechanical ventilation to open up the lung and keep it open. We studied the oxygenation response to a RM (composed of a 30-s sustained inflation at 60 cm H_2O airway pressure) per - formed in prone and supine positions in dogs after oleic acid - induced lung injury using an inspired O_2 fraction of 0.60. In one group (n=6) first supine then prone positions were examined af - ter a RM at 8 cm H_2O and 15 H_2O of positive end - examined pressure (PEEP).
