What type of bleeding involves blood squirting out due to high pressure with every heartbeat?

Arterial bleeding is characterized by blood that spurts out with each heartbeat, which is a direct result of the high pressure within the arteries. The arteries are blood vessels that carry oxygenated blood away from the heart to the rest of the body, and they operate under much higher pressure than veins or capillaries. When an artery is severed or injured, the blood shoots out in a pulsatile manner that coincides with heartbeats, making it visually distinct from other types of bleeding.

This type of hemorrhage requires immediate medical intervention due to the significant volume of blood that can be lost quickly, leading to shock or even death if not controlled. Understanding this aspect is crucial for any EMT, as it dictates the urgency and type of care necessary for the injured individual. In comparison, slow bleeding typically involves a steady seep of blood from smaller vessels, like veins or capillaries, which does not present the same immediate danger as arterial bleeding.
