What is the purpose of using a tourniquet?

The purpose of using a tourniquet is specifically to stop severe bleeding from a limb. When a person experiences a traumatic injury that results in substantial blood loss, especially from a limb, applying a tourniquet can be a lifesaving measure. It works by constricting blood flow to the area, which helps to control or stop the bleeding until emergency medical help can take over.

Using a tourniquet in situations of severe bleeding is critical, especially in instances where there’s a risk of death due to blood loss if immediate intervention is not provided. It is important that tourniquets are applied correctly and only used on severe limb injuries, as inappropriate use can lead to complications such as tissue damage or loss of function.
