This pressures cold blood from the arms and also legs ago toward the heart, lungs and brain, lowering main point body temperature and causing "after drop" which deserve to be fatal. Carry out NOT massage the victim or provide the victim a warm bath. Cardiac arrest is a frequent result of hypothermia, and also moving the victim around can it is in a catalyst for this condition.
