  1. Data are presented as means ± SDs, medians with IQRs in parentheses, or numbers with percentages in parentheses. FiO2, fraction of inspired oxygen; PaO2, partial pressure of arterial oxygen; PEEP, positive end-expiratory pressure; PPV, pulse pressure variation; PCA, patient-controlled analgesia.
