Shock may occur when blood pressure is low. Reduced blood pressure results in less blood and oxygen moving throughout the body. Without oxygen, cells, and eventually the shock victim, will die.
Low amounts of blood may result from severe bleeding (after an accident or internal bleeding caused by a ruptured blood vessel or ulcer), loss of body fluids or poor fluid intake. Inadequate heart pumping may also lead to shock.
Symptoms of shock include, but may not be limited to, fatigue, confusion, cold and sweaty skin, weak and rapid pulse and extremely low blood pressure.
