Fig. 2From: Effects of norepinephrine infusion on cerebral energy metabolism during experimental haemorrhagic shockDynamic changes of median (interquartile range) mean arterial pressure (MAP) throughout the experiment. NE group n = 8. Control group n = 4. Note the steep decrease in MAP in both groups at the start of hypoperfusion period. In addition, note the normalisation of MAP after start of NE infusion.
