The victim who has lost much blood has low blood pressure and must be placed on the back, with the head lower than the level of the trunk and with the legs raised at about 30 cm to facilitate the irrigation of the brain with blood.

Hemorrhage represents the blood leaked from a blood vessel.

In the human body the quantity of blood varies quite a lot depending on factors such as age, sex, health condition, etc. Men have more blood in the body than women even if they have the same height and weight as those 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 of the quantity of blood of an adult. The severity of a hemorrhage is assessed depending on the quantity of blood lost.

Thus, depending on the quantity of blood lost, the hemorrhage can be:

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