The victim who has lost a lot of blood has low blood pressure and must be placed on the back, with the head lower than the level of the torso and with the legs raised about 30 cm to facilitate the blood supply to the brain.

Hemorrhage represents the blood leaked from a blood vessel.

In the human body the amount of blood varies quite a lot depending on factors such as age, sex, state of health, etc. Men have more blood in the body than women even if they have the same height and weight as the respective men. An adult with an average weight, between 70 - 81 kg has between 4.7 - 5.5 liters of blood and a child with a weight between 30 - 40 kg will have approximately half the amount of blood of an adult. The severity of a hemorrhage is assessed according to the amount of blood lost.

Thus depending on the amount of blood lost the hemorrhage can be:

• small (less than 500 ml);
• medium or moderate (1/3 of the amount of blood);
• large (approximately half of the amount of blood);
• lethal (more than half of the amount of blood).
