Tourniquet

Description

A tourniquet is a device that is used to stop bleeding from a wound by compressing the blood vessels in a limb. It is a life saving device that can be used in an emergency, but it should only be used if absolutely necessary.
Tourniquets have a number of features that make them effective at stopping bleeding.
Pressure: A tourniquet applies pressure to the blood vessels in a limb, which helps to stop the flow of blood. The amount of pressure needed to stop bleeding will vary depending on the size of the limb and the severity of the wound.
Tightness: A tourniquet should be applied tightly enough to stop the flow of blood, but not so tightly that it cuts off circulation to the limb. If a tourniquet is applied too tightly, it can cause nerve damage and tissue death.
Location: A tourniquet should be applied as close to the wound as possible. This will help to stop the flow of blood to the wound and prevent further bleeding.
Time: A tourniquet should only be applied for a short period of time. The longer a tourniquet is applied, the greater the risk of nerve damage and tissue death.
