Everyone can be in an emergency.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 particularly important techniques can be found and the rules for the imposition of a harness.
So what you need to know.
First, a tourniquet is needed when a large artery is damaged (in such cases, ordinary dressing and wound bandaging will not help stop the bleeding).
It is important to properly position the harness - five centimeters above the upper wound edge.
So when bleeding from the vessels of the upper limb, the harness will be optimally located at the level of the upper third of the shoulder, and when bleeding from the vessels of the lower extremity - at the level of the middle third of the thigh.
As a harness, you can use a belt, a bandage (folded to increase strength), any fabric, and many other handy things. The harness must be applied on a raised limb.
The density of its imposition must be suchto stop the bleeding. But do not overdo it, otherwise the underlying tissue will remain completely bloodless. As a result, tissue necrosis (death) will occur. Do not forget to put some dense fabric under the rope to reduce local (local) compression in the overlap area. For this purpose, you can impose it directly on clothing.
Harness application rules include one veryan important point to 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 applied. This is necessary in order to overlap the bundle for a long time, to know when it is necessary to loosen it and to give the nutrition to the underlying tissues. Indeed, in anoxic conditions (without blood flow), the tissues begin to die off, which is why it is so important to loosen the tourniquet in time and partially restore blood flow, even for a short period of time.
Remember - you can not impose a tourniquet for more than one or two hours.
В зимнее время года необходимо следить за тем, in order not to get frostbite of a limb tied with a cord, that is, it is necessary to isolate it thoroughly from the cold. In the cold, the maximum squeezing time is reduced to one and a half hours.
It is necessary to carry out weakening of a plait on 10-15minutes, while pressing the bandage on the wound with his hand. The frequency of the implementation of weakening: first, one and a half to two hours from the time of imposition, and then every half hour.
Venous or capillary vascular bleedinglimbs does not require the imposition of harness. In such a case, it is sufficient to stop the bleeding with a tight pressure bandage. Remember to give your limbs a sublime position - this will ease bleeding.
To stop severe bleeding whena large vessel is damaged, and there is no option for applying a bundle, you can resort to an alternative method - finger pressing of a bleeding vessel. In order for it to stop, it is necessary to press the vessel above the injury site to the bone, that is, you need to choose a place for finger pressing, in which the vessel is relatively superficial and passes near the bone.
One of the difficulties of finger pressing is the inability to squeeze the vessel for a long time due to fatigue of the hands.
Aware that the rules of imposingthe hemostat is so important, and that it is often their knowledge that saves lives, you begin to treat the read material with great respect, interest and trembling.
Knowing the technique and the rules for applying a harness, you can provide assistance to people in trouble.
Both the harness overlap rules and the rulesPutting dressings in an emergency will help save your own life or that of your close ones, so do not neglect them, and, from time to time, go back to re-reading this material.
