Applicable Scenarios
A person with a severe enough injury to an artery can bleed to death in three to five minutes, so the regular public needs to know how to stop bleeding.
With severe bleeding, death can occur within 3 to 5 minutes.
Gunshot Wound

A gunshot wound (GSW) is a penetrating injury caused by a projectile (e.g. a bullet) from a gun (typically firearm or air gun). Damage may include bleeding, bone fractures, organ damage, wound infection, loss of the ability to move part of the body, and in severe cases, death.
Stab Wound

A stab wound is a specific form of penetrating trauma to the skin that results from a knife or a similar pointed object. While stab wounds are typically known to be caused by knives, they can also occur from a variety of implements, including broken bottles and ice picks.
Cut Wound

A cut is a break or opening in the skin. It is also called a laceration. A cut may be deep, smooth, or jagged. It may be near the surface of the skin, or deeper. A deep cut can affect tendons, muscles, ligaments, nerves, blood vessels, or bone.
Blast Wound

A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. Blast injuries range from internal organ injuries, including lung and traumatic brain injury (TBI), to extremity injuries, burns, hearing, and vision injuries.
Arterial / Venous Bleeding

Arterial bleeding comes out in spurts, venous bleeding flows steadily, and capillary bleeding trickles from the body.
Arterial bleeding is the most severe and urgent type of bleeding. It can result from a penetrating injury, blunt trauma, or damage to organs or blood vessels.
Because the blood comes from the arteries, it is distinctive from the other types of bleeding. For example, the blood is bright red due to it containing oxygen. It also comes out in spurts and pulses, which correlate to the beats of the heart. This type of bleeding can be hard to control because the pressure from the beating heart means that it will not clot or stop as easily.
Venous bleeding is less severe than arterial bleeding, but it can still be life threatening. For this reason, it requires immediate medical attention.
As the blood is coming from a vein, it is dark red. This is because it does not contain as much oxygen. Also, because veins are not under direct pressure, the blood flows steadily but comes out less forcefully than it does with arterial bleeding.
Open fracture, combined with life-threathening bleeding

An open fracture is an injury where the fractured bone and/or fracture hematoma are exposed to the external environment via a traumatic violation of the soft tissue and skin. The skin wound may lie at a site distant to the fracture and not directly over it. Therefore, any fracture that has a concomitant wound should be considered open until proven otherwise.
