Explanation:
In arterial bleeding, the arteries carry oxygenated blood away from the heart; so when bleeding it's in rapid spurts. The pressure inside the artery doesn't help, so there's rapid blood loss. This causes the oxygen supply in the body to decrease drastically. It can lead to stroke, heart attack, and death.
To prevent this, she might be treated by applying direct pressure on the wound using a clean, thick dressing to prevent more bleeding. Hold it in place and don't lift it to see if there's bleeding.
