Is there a regulation on the time it takes for a tourniquet to stop bleeding?

When using a tourniquet to stop bleeding, you still have to master the methods and techniques, and you cannot allow the bleeding to continue. So is there a regulation on the time it takes to stop bleeding with a tourniquet? Only by following the correct method of first aid for stopping bleeding and relaxing after a period of time will you not endanger human health and safety. In addition, you also need to have a clear understanding of the specific bleeding sites in order to achieve better hemostatic effects.

After selecting the location of the tourniquet, you should first place a cloth strip there, tighten the tourniquet, wrap it around the limb twice and tie a knot. The tightness should be appropriate, and the wound should stop bleeding. Remember the time when putting on the tourniquet. Loosen it for 1/2 minute every half hour in winter and every hour in summer, and then tie it up again. When tying again, move the part slightly up and down. Patients with severe bleeding should be sent to the hospital for treatment as soon as possible while applying a tourniquet.

Clean the wound with sterile water (boiled water), use clean fingers to gently find the deep artery, and carefully tie the artery with sterile thread. This was the first time the open wound had been touched. If the artery is completely severed, the ends may atrophy and be difficult to find. Once you are sure the artery is in a small area of ​​tissue, you can use a large needle to sew the entire area shut.

While checking whether the operation was successful, loosen the hemostatic bandage as soon as possible to find out whether the artery causing the bleeding is the only one that has been bandaged. If bleeding is still found, the tourniquet should be re-applied immediately and the search for ruptured blood vessels should continue. There are other small blood vessels in the tissues that provide the limbs with the blood necessary to maintain physiological metabolism and maintain circulation. Do not leave the tourniquet in place.

There are only two areas where you should use a tourniquet: the forearm (just below the armpit) and the upper thigh. Choose a cloth tape that is at least 5 cm (2 inches) wide to use as a tourniquet. If you are forced to use narrower lines (wires or ropes), you must pad them with multiple layers of folded cloth to reduce discomfort and avoid damage to nerves or muscles.

Through the above introduction, everyone is clear about whether there are regulations on the tourniquet's bleeding-stopping time. There are many specific regulations and requirements for the use of tourniquets, and you need to master them to achieve better hemostatic effects. Then the patients should be sent to the hospital as soon as possible and receive formal and systematic treatment to help them recover from the danger.
