Apr 28, 2008 #2 uscgk9 Forum Crew Member 49 0 0 Well that would have to depend on several factors. The human body has approx 70ml of blood for every kg of patient. 150 lb.....68kg......4,760ml. A previously healthy individual should start to show signs of hypovolemic shock after loosing approx 20% of its total blood volume. 4,760ml........20%........952ml.........a little less than a 1000ml bag of fluid. hope that helps.
