Mortality at day 30 according to stratification by severity of impairment of peripheral perfusion index (PI) after normalization of central venous oxygen saturation (ScvO2) (≥70 %) at 8 h (T8). *P <0.05; ns not significant. PI ≥1.4 (normal PI, n = 105); 0.6 < PI <1.4 (PI mild impairment n = 37); PI ≤0.6 (PI critical impairment, n = 25)
