Shock is a life-threatening condition that occurs when the organs receive too little oxygen. It can cause organ damage and even death. People go into shock when their blood pressure becomes so low that the body’s cells do not get enough blood. Thus, they do not receive the oxygen they need. Because of this, cells in many organs, including the brain, kidneys, liver, and heart, cease to operate normally. Blood flow must be quickly restored to these cells before they become permanently impaired and die. Enough damaged or dead cells can lead to failure of the organ in which they reside.
