Arterial hemorrhage is a type of bleeding that occurs when an artery is damaged, causing blood to flow out of the circulatory system. This type of bleeding is often characterized by bright red blood that spurts with each heartbeat, indicating that the blood is under high pressure. Common causes include trauma, such as cuts or injuries, and medical conditions that weaken blood vessels. Immediate medical attention is crucial for arterial hemorrhage, as it can lead to significant blood loss and shock. Treatment typically involves applying direct pressure to the wound, elevating the affected area, and seeking emergency care to control the bleeding and repair the damaged artery.
