The Simplified Acute Physiology Score (SAPS) II was used to assess the severity of systemic illness at study entry. The Sepsis-Related Organ Failure Assessment (SOFA) was used to assess the organ failure at the day of the study. ALI, acute lung injury; ARDS, acute respiratory distress syndrome; BMI, body mass index; D, dead; F, female; M, male; MAP, mean arterial pressure; PEEP, positive end-expiratory pressure; S, survived; SD, standard deviation.
