Shock is a condition of severe depression of the vital functions. It is associated with changes in the circulatory system, varying from temporary weakness to complete failure. Its severity varies with the nature and extent of the injury and it is a common cause of death following severe injuries.
Shock may develop at once or its onset may be delayed. Loss of whole blood or plasma from the circulation is the most important cause of shock. The severity of shock depends on the amount and rapidity of bleeding. A badly shocked victim will look pale, bluish, cold and sweaty and will also be mentally slow.
