This study prospectively evaluated 17 patients with ARDS who underwent pulmonary artery wedge pressure PAWP measurement and simplified acute physiology score. All of them were treated by endotracheal intubation and positive end expiratory pressure (PEEP) assisted breathing to ensure FiO_2 <0.6, arterial oxygenation full
