While providing first aid for a bleeding wound, when should you consider using a tourniquet?

Using a tourniquet is an important skill in first aid for severe bleeding, and the decision to employ one should be based on the severity of the bleeding. A tourniquet is typically indicated only if the bleeding is life-threatening and cannot be controlled with direct pressure or other methods. Life-threatening bleeding is characterized by significant blood loss, which may occur rapidly and puts the individual's life at immediate risk.

In situations where direct pressure on a wound is ineffective, or when a wound is located on a limb and the bleeding is profuse, applying a tourniquet can be crucial. It can help restrict blood flow to the affected area, ultimately preventing exsanguination while waiting for advanced medical assistance. The use of tourniquets, especially in less severe situations, can lead to unnecessary complications, including tissue damage and limb loss, which is why they should be a last resort for critical injuries.
