Depending on the amount of blood lost, we can distinguish:

• large hemorrhages, fatal, when more than half of the total amount of blood is lost;
• medium hemorrhages, when 1/3 of the total amount of blood is lost;
• small hemorrhages, when an amount of 500 - 600 ml of blood is lost.

The abundant flow of blood, internal or external, following the rupture or cutting of the wall of a blood vessel is called hemorrhage. Hemorrhage is caused by damage to the integrity of the vessel, caused by trauma, purulent lysis of the vessel wall, disruption of blood chemistry.

Hemorrhages are of two types:

• External hemorrhages. In which the blood flows outside the body due to the cutting of blood vessels;
• Internal hemorrhages. In which the blood that flows remains inside the body (e.g.: in the abdominal cavity).

External and exteriorized hemorrhages are easy to recognize. Internal hemorrhages are accompanied by a series of signs through which they can be suspected and diagnosed. These signs are: dizziness, increased number of heartbeats per minute, increased number of breaths per minute. The patient's pulse is weak, and his blood pressure drops far below the normal figure. The patient is restless, pale, speaks quickly, has cold sweats and is tormented by an unusually great thirst.
