Arterial blood gas parameters. *P < 0.05 compared with C‐C; ^# P < 0.05 compared with E‐C.C‐C: control; C‐LPS: normal lung with sepsis; E‐C: emphysema without sepsis; E‐LPS: emphysema with sepsis. Values are expressed as mean ± SD or median (interquartile range) for normally and non‐normally distributed data respectively. Statistical analysis was performed using one‐way anova followed by Tukey test or by Kruskal–Wallis test followed by Mann–Whitney U‐test, for normally and non‐normally distributed data respectively. Adjustments for repeated measures were made according to the Bonferroni correction.
