Table 1 The first part of the table displays Kruskal-Wallis test results regarding differences between groups in the development of PaO2 and PaCO2, respectively, from before cardiac arrest to both the first and the second quarter. The second part of the table displays the bonferroni corrected p-values from pairwise comparisons between groups performed by the Dunn’s post hoc test regarding PaO2 and PaCO2
