Bonferroni test. Friedman test. TCC: total number of chest compressions (during two minutes). D: depth of chest compression (mm). R: chest compressions rate (per minute). V: ventilations (during two minutes). TVI: total volume inflated (ml during two minutes). MTV: mean tidal volume (ml per ventilation).
