Severe external bleeding can often be controlled by which action?

Severe external bleeding is a critical situation that requires immediate action. Applying pressure to the wound is the most effective method to control this type of bleeding. When direct pressure is exerted on the wound, it helps to compress the blood vessels and minimize blood loss. This physical action prompts the body’s natural clotting mechanisms to begin working, thus aiding in the formation of a blood clot at the site of the injury.

In cases where bleeding is severe, this direct pressure should be maintained and, if necessary, additional layers of sterile dressing can be added without lifting the initial dressing, as lifting it may disrupt any clot that has begun to form. Understanding the importance of this immediate response can significantly affect outcomes in emergency situations and should be a fundamental skill for anyone involved in outdoor activities where injuries might occur.
