First Aid for Shock First aid for shock after an injury includes measures to arrest bleeding, maintaining an open airway, keeping the victim flat, reducing heat loss with blankets, and reassurance. You may use a hot-water bottle to warm the victim. Lay the victim down and raise the legs about 12 inches so that blood flows from the legs to the upper body. Loosen tight clothing and wrap the victim in a coat or blanket to prevent heat loss. Emergency treatment in the hospital involves an infusion of fluid or a blood transfusion, oxygen therapy, and, if necessary, morphine or similar powerful painkillers.
Further treatment depends on the underlying cause.
