What should an EMR do after applying direct pressure to an arterial bleed that continues to bleed?

After applying direct pressure to an arterial bleed that continues to bleed, using a tourniquet above the injury site is the appropriate action. This method serves to constrict blood flow and aid in controlling severe bleeding that has not responded to direct pressure.

When an arterial bleed is present, it can be life-threatening if not managed quickly and effectively. While applying pressure to the brachial pulse point may seem helpful, it is not a reliable method for stopping arterial bleeding and can delay critical assistance needed for a patient in this situation. Elevating the arm above the heart can help with venous bleeding but will not be effective against arterial bleeding. Calling for immediate advanced medical assistance is necessary, but it should come after taking definitive action, such as using a tourniquet, to control the bleeding.

Utilizing a tourniquet is a standardized emergency response for severe bleeding, particularly in situations where direct pressure fails to control the hemorrhage, making it the most effective and immediate choice to prevent further blood loss and potential shock.
