Open damage is conspicuous, so detecting them can be quite easy. Wounds that are covered with clothing can go unnoticed, and this is very dangerous. The main thing when examining - to determine the presence of acute blood loss, regardless of the size of the wound in the victim. It is also worth checking the victim's breathing, his pulse and pressure.

If you find damage to large vessels, then stop blood loss by using the method of pressing the artery with your finger. It should be remembered that this method is temporary. Usually this is done in order to have time to carefully prepare a pressure bandage.
If external damage is observedlimbs, the pressure bandage, as a rule, is not enough. In such cases it is better to use a tourniquet or its analogue. Can come handy tools, such as a tie, belt, headscarf or handkerchief. It must be applied several centimeters above the bleeding site, after which it is necessary to leave a note indicating the time of application of the tourniquet. You can leave it for a certain period: up to two hours in summer and up to 30 minutes in winter. For this time it is necessary to deliver the victim to the hospital.

Finally, stopping heavy bleeding will help suturing the wound.
If the deep veins are damaged, it is necessary to woundstightly pound tampons with hydrogen peroxide. After carrying out of the given procedure it is necessary to impose a pressing circular bandage, and enough rigid. All further actions should be performed by a doctor, and the earlier he begins to process the wound, the better for the patient.
If there are damage to the vessels of the neck,it is required to press the fingers of the ends of the bleeding vein through the skin, and in the wound itself to clamp the vessel. After that, tampons must be packed with hydrogen peroxide. After first aid, the doctor must apply seams.
