What is the best method to control severe arterial bleeding from a neck puncture wound?

Direct pressure by pushing the injured artery ends is the most effective method to control severe arterial bleeding from a neck puncture wound. This approach involves applying firm fingertip pressure directly on the bleeding site to compress the artery, thereby reducing blood flow and helping to clot the wound. The neck has several major arteries, and direct pressure can significantly help in mitigating the risk of excessive blood loss until further medical assistance can be obtained.

Applying a tourniquet above the wound is typically used for extremities and may not be suitable or effective for neck injuries, where structural concerns and the presence of vital structures make tourniquets less ideal.

Using ice to numb the area can provide localized analgesia but does not effectively control bleeding and may even complicate the situation if not managed appropriately.

Elevating the head of the casualty may improve the overall circulation or breathing but would not directly address the severe arterial bleeding from a puncture wound, making it an ineffective choice in this urgent scenario.
