What is the correct technique for controlling severe bleeding?

The correct technique for controlling severe bleeding involves several critical steps that prioritize immediate and effective intervention to prevent excessive blood loss. Applying direct pressure to the wound is essential because it helps to compress the blood vessels and can significantly reduce or stop the flow of blood. Elevating the injured area, if possible, assists in minimizing blood flow to the site by using gravity, which can be beneficial in controlling bleeding.

In cases where direct pressure and elevation do not sufficiently control the bleeding, the use of a tourniquet becomes crucial. Tourniquets are designed to constrict blood flow to the extremities, thereby preventing significant blood loss in life-threatening situations. It is important to apply a tourniquet properly and at the correct location on the limb to maximize its effectiveness.

Other methods listed in the options, such as applying ice or administering aspirin, are not appropriate for managing severe bleeding. Ice might be used to reduce swelling or pain in certain scenarios but does not effectively control bleeding. Aspirin can actually exacerbate bleeding by inhibiting platelet function, which is counterproductive in a bleeding emergency. Injecting a clotting agent directly into a wound could pose risks, including introducing infection or complications, and is not a standard approach for immediate bleeding control in pre-hospital care
