Which type of bleeding is indicated by bruising and contusions?

Bruising and contusions are indicative of internal bleeding because they occur when blood vessels are damaged or ruptured beneath the skin, allowing blood to leak into the surrounding tissue. This process does not involve an open wound, which distinguishes it from external bleeding, where blood flows out of the body through a visible cut or injury. Internal bleeding can happen due to various causes, including trauma, falls, or other injuries, and is often characterized by symptoms such as swelling, pain, and changes in skin color. Recognizing bruising as a sign of potential internal injury is crucial for assessing a person's condition and determining the appropriate response for medical care. Understanding this distinction helps lifeguards and responders make informed decisions when providing assistance to individuals who may be experiencing more serious underlying injuries.
