How can one identify arterial bleeding?

Identifying arterial bleeding is crucial in emergency response because it can lead to rapid blood loss and requires immediate attention. When bleeding spurts from the wound, it indicates that the source is an artery, as arteries carry oxygenated blood away from the heart under higher pressure than veins. This spouting or pulsing effect is typically synchronized with the heartbeat, which distinguishes it from other types of bleeding.

In contrast, steady bleeding generally suggests venous bleeding, where blood flows more uniformly. Slow oozing indicates capillary bleeding or possibly venous bleeding, which is less urgent than arterial bleeding. Additionally, the color of the blood can provide clues; oxygen-rich arterial blood is bright red, whereas venous blood, which is darker, has already delivered oxygen to the tissues. This knowledge helps first responders assess the situation quickly and prioritize treatment accordingly.
