ABC of Safety in the Biological Sciences
Shock is the loss of effective circulating blood volume accompanying severe injury or sudden illness.123 The immediate signs are pallor, sweating and a slow pulse rate which becomes rapid and feeble and is accompanied with shallow respiration.
Lay the victim down, lower the head and raise the feet slightly. Prevent heat loss by covering with a light blanket but do not apply heat. Do not give anything to drink unless the victim is fully conscious. If the victim is unconscious place in a coma position ensuring a clear airway. Stay with the victim until a complete recovery has been effected or trained staff arrive. Check airway breathing and pulse rate regularly. If the shock is a result of severe injury which may require surgery, do no allow the victim to eat or drink anything.
