What is the best treatment for shock?

Find the cause. Shock is a general term that refers to a condition where the body is trying desperately to maintain stability of normal vital signs, but failing. There are several major types of shock, depending on the reason for the condition. Trauma, infection, spinal cord injury, and cardiac failure are some of the more typical reasons. The best treatment differs for each category.
Call 911. Shock of any cause is a life threatening condition requiring emergency medical attention. While the treatment depends on the cause, only emergency responders and physicians can determine the cause and treat appropriately to save someone's life.
