If the damaged arteries are close to the skin, the victim bleeds quickly and blood spurts from wounds, each spurt occurring with a beat or pump of the heart. A large amount of blood is projected, leaving a distinctive arched bloodstain pattern. As the victim bleeds profusely, his or her blood pressure declines and the spurting becomes less intense; therefore, spurting bloodstains vary in size, becoming smaller and projected shorter distances. This spatter is typically seen on a vertical surface, such as a wall, in arch-like shapes of decreasing sizes. As noted earlier, arterial blood is rich in oxygen and has a bright red color.”
