Is severing the external carotid artery fatal

Severing the external carotid artery can lead to significant blood loss and can be life-threatening, depending on the extent of the injury and the speed of medical intervention. The external carotid artery supplies blood to the face and neck, and injury to this artery can cause severe bleeding. If the wound is not treated quickly, it can result in hypovolemic shock, which is a dangerous condition resulting from loss of blood volume and can ultimately lead to death. If someone suffers such an injury, it is critical to seek emergency medical care immediately. Initial first aid steps may include applying direct pressure to control bleeding until professional medical help arrives.
