# Shock onset for septic group.

°C, Celsius degrees; HR, heart rate; CI, cardiac index; MAP, mean arterial pressure; MPAP, mean pulmonary arterial pressure; SVRI, systemic vascular resistance index; PF, PaO2/FiO2; TPC, thoraco-pulmonary compliance.

No interference between time and groups was found for all the studied variables in ANOVA analysis. Significant at 5% vs. baseline (a), vs 6 hours (b) or vs 12 hours (c) or significant at 5% vs. sham (*) in post-hoc Bonferroni correction.
