Fig. 4From: Marked regional endothelial dysfunction in mottled skin area in patients with severe infectionsAnalysis of skin microcirculatory blood flow measured in three groups of patients: patient with sepsis (n = 11), 14-day survivors with septic shock (n = 18), and 14-day non-survivors with septic shock (n = 8). Skin blood flow was quantified on the forearm and the knee area at baseline (a, d) and after acetylcholine iontophoresis (peak value (b and e) and area under the curve (AUC) (c and f). *P < 0.05, **P < 0.01.
