arterial spray

Arterial spray refers to the pattern of blood that can be seen when a large artery is severed or injured. When an artery is cut, blood is expelled forcefully and in a pulsating manner, creating a spray or mist-like pattern. This occurs because arteries carry blood under high pressure from the heart, causing the blood to spurt out with each heartbeat. Detecting arterial spray during an investigation can indicate significant vascular injury and help locate the source of bleeding, often seen in forensic or medical contexts.
