Table 2 The ratio of PaO2 and FiO2 at baseline level and different time points after operation

From: Plasma level of advanced oxidation protein products as a novel biomarker of acute lung injury following cardiac surgery

PaO2:FiO2 ratio Before operation 1 h after operation 12 h after operation 24 h after operation 48 h after operation
ALI 418 ± 29.5 365 ± 31.6 314 ± 40.2a 270 ± 43.1a 256 ± 48.2a
