  1. Oxygenation index was calculated as mean airway pressure × FiO2 × 100)/PaO2. Results are provided as mean ± SD
  2. FiO2, inspired oxygen fraction; PEEP, positive end-expiratory pressure; mPaw, mean airway pressure; IPBW, ideal predicted body weight; SAPS II, Simplified Acute Physiology Score II; SOFA, Sepsis Organ Failure Assessment Score; V t, tidal volume
