Objectives: To determine the validity of electrical impedance tomography to detect and
quantify the amount of tidal recruitment caused by different positive end-expiratory pressure
levels in a porcine acute lung injury model. Design: Randomized, controlled, prospective
experimental study. Setting: Academic research laboratory. Subjects: Twelve anesthetized
and mechanically ventilated pigs. Interventions: Acute lung injury was induced by central
venous oleic acid injection and abdominal hypertension in seven animals. Five healthy pigs …
