  1. FiO 2 = Inspired oxygen fraction, PaO 2 = arterial oxygen partial pressure, PaCO 2 = arterial carbon dioxide partial pressure, PvO 2 = venous oxygen partial pressure, PvCO 2 = venous carbon dioxide partial pressure. HBD = heart-beating-donor group, DCD = donation after cardiac death. Significance was defined as p < 0.05 (*), p < 0.01 (**), p < 0.001 (***) and p > 0.05 (n.s.)
