Fig. 1From: A technique for continuous bedside monitoring of global cerebral energy stateMedian (interquartile range) arterial pressure (MAP) and brain tissue oxygen tension (PbtO2) in pigs with induced hemorrhagic shock. Note that during the period of hemorrhagic shock, the declining MAP was accompanied by a decrease in PbtO2 to a very low level (<5Â mmHg). After re-infusion of autologous blood, MAP increased to close to baseline level whereas PbtO2 remained very low. S indicates the start of bleeding to achieve a MAP of 40Â mmHg. The black bar on the x-axis from 0 to 90Â min indicates the shock period before resuscitation was startedBack to article page
