What is the main purpose of a tourniquet in field bleeding control?

• A. To stop all bleeding immediately
• B. To stop arterial bleeding and limit blood loss
• C. To administer medications
• D. To immobilize joint

Answer: (C)

The main purpose of a tourniquet in field bleeding control is to rapidly stop life-threatening bleeding by occluding arterial inflow to a limb, thereby dramatically reducing blood loss and buying time to get the person to definitive care. Direct pressure is tried first, but when bleeding is severe or cannot be controlled with pressure alone, a tourniquet applied high and tight can halt arterial flow and prevent continued blood loss. It’s not used to administer medications or to immobilize a joint. The goal is to limit bleeding and save life, with the understanding that tissue damage from loss of blood flow can occur if left on too long, so medical follow-up is essential.
