A tourniquet is a special device used to stop blood flow in an arm or leg. It works by putting pressure around the limb, which temporarily blocks the blood vessels. This tool is mainly used by medical professionals, like military medics, to control serious bleeding, especially when someone is in danger because they are losing too much blood.

What is a Tourniquet and How Does It Work?
A tourniquet is a tool that squeezes a limb tightly. Imagine a strong bandage wrapped around an arm or leg. This pressure pushes on the blood vessels, like veins and arteries, stopping blood from flowing through them for a short time. This is very important in emergencies to prevent a person from losing too much blood.
Why Are Tourniquets Used?
Tourniquets are used in serious situations where someone is bleeding very heavily from an arm or leg. This kind of bleeding can be life-threatening. By stopping the blood flow, a tourniquet gives medical helpers time to get the person to a hospital or provide more advanced care. It's a critical tool for saving lives in emergencies.
Different Kinds of Tourniquets
Long ago, people made simple tourniquets from things like a stick and a rope or a leather belt. The rope would be looped around the injured limb, and the stick would be twisted to tighten the loop. While these old methods could stop bleeding, they sometimes caused other problems, like damage to the skin, muscles, or nerves.
Modern Tourniquets
Today, there are much safer and easier-to-use tourniquets. These modern devices are designed to avoid the side effects of older methods. They can be applied very quickly. Some modern tourniquets, like the Combat Application Tourniquet or the SOF Tourniquet, are so well-designed that an injured person can even put one on themselves with just one hand. However, it's still important to practice using them so you know how to apply them correctly and fast in an emergency.
