  1. Data are presented as mean ± SD. SOFA: Sequential Organ Failure Assessment Score. SAPS II: Simplified Acute Physiology Score. Crs: static compliance of respiratory system. PEEP: positive end-expiratory pressure. PaO2/FiO2: ratio of arterial oxygen partial pressure to fractional inspired oxygen. PaCO2: arterial carbon dioxide partial pressure. Vt/PBW: ratio of tidal volume to predicted body weight. dP: driving pressure. WBC: White Blood Cells. CRP: C Reactive Protein
