PaO2/FiO2 ratio as a function of FiO2 for all patients. At FiO2 0.21 measurements were performed in 7 patients to ensure adequate saturation. At FiO2 ≥ 0.3 all patients were measured. Median, interquartile range and minimum/maximum are shown for every FiO2. Asterisks denote significant differences (P < 0.05) between the denoted FiO2 level and FiO2 of 0.8 and 1.0
