Fig. 1From: Skin microcirculatory reactivity assessed using a thermal challenge is decreased in patients with circulatory shock and associated with outcomeComparison of skin blood flow measurements at different temperatures on the forearm and the hand in healthy volunteers. In the right panel, the ratio of skin blood flow obtained between 43 and 37 °C is presented. *p < 0.05 compared with measurements at 37 °C; #p < 0.05 compared with forearm measurementsBack to article page
