What is shock?

Shock is a life-threatening condition in which the circulation fails to deliver enough oxygen-rich blood to the body's tissues. When blood flow and oxygen delivery are inadequate, cells and organs can start to fail, making rapid treatment essential. This description directly captures the core problem: insufficient circulation leading to insufficient oxygen for the body's needs. The other statements describe conditions that aren’t shock—mild allergic reactions, fever, or a normal fitness response to exercise—so they don’t reflect the dangerous failure of circulation and oxygen delivery that defines shock. If someone shows signs like pale, cold skin, rapid pulse, or confusion, urgent medical help is needed.
