Final answer:
The severity of an external bleed can be categorized as minor, moderate, or major. Minor bleeds are small and managed by the body's natural clotting. Moderate bleeds require pressure and bandaging, while major hemorrhages are life-threatening and need immediate medical attention.
Step-by-step explanation:
Levels of Bleeding
When assessing an external bleed, it's important to determine the severity to provide the appropriate care. A minor bleed might be from a small cut or abrasion where blood loss is minimal, and the body's hemostasis mechanism can manage it through clotting and repair. A moderate bleed may involve a larger wound with more persistent blood flow that may require pressure and bandaging to control. A major hemorrhage occurs when there's significant and uncontrolled blood loss, often from a severe injury to large blood vessels, posing an immediate health threat that necessitates emergency medical intervention to restore blood volume and maintain vital functions.
