Of all the bleeding arterial bleeding is considered the most dangerous. Before understanding the features of arterial bleeding, it is necessary to explain the significance of the arterial system as a whole.
So, the human arterial system is a system of arteries - the largest vessels that transport blood to the heart.
Arteries are located deep enough, however, if arterial bleeding does occur, a person, if not provided with timely assistance, can quickly die.
In particular, if the sleepy, femoralor axillary artery, then death can occur within two to three minutes. In order to prevent such an outcome, it is necessary to stop the flow of blood to the site of injury. For this, the artery is clamped a little higher than the wound. There are a number of points on the human body, by clicking on which, you can easily and quickly pinch one or another artery.
Но такого рода помощь является временной, она valid until they make a pressure bandage. Arterial bleeding should be stopped quickly. Because the road is every second. Blood beats like a fountain (blood pulsation occurs according to the rhythm of the heart), so there may be a lot of blood loss. On average, you have only 1-2 minutes to provide first aid.
It is necessary to stop arterial bleeding in stages. The first stage - pressing the artery to the skin. Then begins the second stage - the imposition of a dressing (harness).
During how bleeding occurs fromfemoral artery, often applying a pressure bandage does not completely help. Such bleeding can be stopped by applying a loop or bundle. If you cannot find a medical harness, use something that can replace it - a kerchief, tie, diaper, etc. When applying a tourniquet, it is necessary to cover the place of application with gauze or a bandage so as not to transmit the skin and nerve endings.
There are certain principles for applying a tourniquet according to the location of the damage to the artery:
- If the artery is damaged in the area of the upper limbs, the tourniquet should be applied in the upper part of the shoulder. When the lower limbs are injured, the imposition is performed in the middle of the thigh.
- It is necessary to impose a harness rather tightly, but not pinch the fabric. There may be serious consequences (due to the clamping, the blood stops circulating)
- It is important to remember that it is necessary to notetime when a tourniquet was applied. The mark should be left on paper, and attach this note to the clothing of the victim. Then this time is indicated in the medical record.
- IMPORTANT: it is forbidden to apply a tourniquet in the area of the lower extremities for more than an hour and a half, and in the shoulder area - for more than 45 minutes.
- Remember that arterial bleedingterminated only with the correct application of the harness. Also know that it is forbidden to put a bandage on top of the harness: the harness itself should be clearly and clearly visible.
When the victim received first aid, hisurgent need to transport to a medical facility. If it is not possible to do this quickly, then after the maximum period of application of the bundle, it should be slightly loosened by a quarter of an hour, and then tightened again.
There is the concept of hidden bleeding.They are so called because they are not visible to the naked eye. Such bleeding may occur in patients with gastric or duodenal ulcer. Blood loss in this case is very dangerous, since anemia is rapidly developing. This kind of bleeding is determined in special laboratory conditions in the study of feces for the presence of hidden blood.
Remember that arterial bleeding is very dangerous for a person's life, so if you had to provide medical care to such a patient, do it quickly and confidently!
