Rules for applying a harness.

In an emergency, everyone can be. No one is immune from all sorts of injuries and injuries, which is why it is so important, and sometimes even vital, to know some aspects of first aid. Among such especially important techniques, it is possible to meet the rules for applying a tourniquet.

So, what you need to know.

First, the tourniquet is needed when the large artery is damaged( in such cases, ordinary dressing and bandaging of the wound will not help stop the bleeding).
It is important to correctly arrange the tourniquet - five centimeters above the upper wound edge.

So when bleeding from the vessels of the upper extremity, the location of the tourniquet at the level of the upper third of the shoulder will be optimal, and with bleeding from the vessels of the lower limb - at the level of the middle third of the thigh.

As a tourniquet, you can use a belt, bandage( folded layers to increase strength), any fabric and many other handy things. The tourniquet should be placed on the raised limb.

The density of its superposition should be such that the bleeding ceases. However, do not overdo it, otherwise the underlying tissues will remain completely bloodless. As a result, necrosis( death of tissues) will occur. Do not forget to put a dense cloth under the harness to reduce local( local) compression in the area of ​​application. For this purpose, you can put it directly on your clothes.

Rules for the harnessing include one very important point, forget about which is not in any case. Attach to it a sheet of paper or cardboard, on which write the time when it was imposed. This is necessary in order to know, in case of applying a tourniquet for a long time, when it is necessary to weaken it and give the underlying tissues "food".After all, in anoxic conditions( without blood flow), tissues begin to die, which is why it is so important to weaken the tourniquet in time and partially restore the blood flow, even for a short period of time.
Remember - you can not apply a tourniquet for more than one or two hours.

In winter, it is necessary to ensure that you do not get frostbite from the limb by bandaging a bundle, that is, you must thoroughly isolate it from the cold. In the cold, the maximum squeezing time is reduced to one and a half hours.

Weak loosening is necessary for 10-15 minutes, while pressing the bandage on the wound with your hand. Frequency of attenuation: first one and a half to two hours from the time of application, and then every half hour.

Venous or capillary hemorrhage from the vessels of the extremities does not require the application of a tourniquet. In such a case, it is enough to stop bleeding with a tight pressure bandage. Do not forget to give the limb an elevated position - it will weaken the bleeding.

To stop severe bleeding, when a large vessel is damaged, and there is no option of applying a tourniquet, you can resort to an alternative method - finger pressing of the bleeding vessel. In order for it to stop, it is necessary to press the vessel above the wound site to the bone, that is, it is necessary to choose such a place for finger pressing, in which the vessel is relatively shallow and passes near the bone.

One of the difficulties of finger pressure is the inability to squeeze the vessel for a long time due to fatigue of the hands.
