Fig. 2From: Comparison of the effect of membrane sizes and fibre arrangements of two membrane oxygenators on the inflammatory response, oxygenation and decarboxylation in a rat model of extracorporeal membrane oxygenationOxygen partial pressure. ECMO began with FiO2 at 1.0, and the pO2 was measured after 15 min – the FiO2 was adjusted to 0.75, 0.5 and 0.21 respectively. Values are expressed as medians with Min/Max values, * indicates that values are statistically significant different (p < 0.05), tested by using the Wilcoxon–Mann–Whitney testBack to article page
