Define Hypovolemia or Reduction in Blood Volume

Hypovolemia leads to a decrease in cardiac output, which causes a fall in the systemic blood pressure. Hypovolemia may be produced by hemorrhage. However, the baroreceptor reflex corrects the fall in blood pressure due to moderate hemorrhage. If the loss of blood is less than 10% of the total blood volume, the compensatory mechanisms succeed in stabilizing the blood pressure at a level below the normal pressure. But if the loss is more than 3096 of the blood volume, the compensatory mechanisms may fail leading to an irreversible and fatal fall in blood pressure.
