Parameters of systemic hemodynamics, lung mechanics, pulmonary gas exchange, metabolism, and acid-base.

§ depicts p < 0.05 vs. the corresponding Non-CS group, $ depicts p < 0.05 vs. the corresponding air group (K-W ANOVA Kruskall-Wallis analysis of variance on ranks with post-hoc Dunn’s test for multiple comparisons). Parameters of systemic hemodynamics, lung mechanics, pulmonary gas exchange, metabolism, and acid-base status in mice without (Non-CS) and with (CS) cigarette smoke exposure over three to four weeks prior to blunt chest trauma and after four hours mechanical ventilation with air (FiO2 0.21) or 100% O2 (FiO2 1.0) (n = 8 in each group). All data are median (quartiles).
