What to Do? and also What not to Do!

Any victim pulled from cold water have to be treated because that hypothermia - this is the really dangerous and important stage of survival which is a an outcome of cold water immersion.

Execute NOT use heat come the arms and legs. 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.
