Fig. 1From: Effects of norepinephrine infusion on cerebral energy metabolism during experimental haemorrhagic shockExperimental protocol timeline. Note that the experimental protocol is divided into four intervals. Interval 1: Baseline − 60–0 min. Interval 2: Hypoperfusion period 0–90 min, Interval 3: Stabilisation period 90–180 min in which physiological state might return to homeostasis. Interval 4: post-resuscitation period 180–240 minBack to article page
