“First aid in case of external bleeding:

* Ensure airway patency.
* Assessment of breathing and circulation.
* Advise and assist the victim to lie down on the prevention of fainting.
* Direct pressure on the wound with dressings.
* Elevation of the affected limb.
* If the bleeding does not stop, arterial compression.
* Ultimately tourniquet application, indicating the time of application.
* Prevent or hypovolemic hemorrhagic shock.

The tourniquet is a maneuver aimed at alleviating acute hemorrhage, which can not be contained by the conventional system, by compressing the blood vessels in a circular area next.

It is useful in traumatic amputations of limbs, crushing extended or when conventional measures have failed, but it involves some risks: gangrene, death by auto-intoxication.

The tourniquet must be applied between the wound and the heart. Once applied, it should be removed only in the presence of a physician. Should not be used, if possible, rope, wire or other fine objects that could “cut” to compress, it is usual to use a triangular folded handkerchief or something similar with sufficient width (5 cm. Approx.).

It is very important to reflect on a large paper stuck to the victim or by writing directly to the skin, preferably in the front (the sweat can remove some inks), time and location of the tourniquet and should be pursued not keep hiding the light clothes or other objects.

Hypovolemic shock is a clinical state in which the amount of blood into the cells is insufficient or inadequate to enable them to perform their normal function.

The symptoms are:

* Pale, clammy skin.
* Restlessness, thirst.
* Weak and rapid pulse.
* Slow and deep, sometimes noisy.
* Drowsiness.
* And, if continued, will trigger a coma.
