What to Do? and also What not to Do!

Any victim traction from cold water need to be treated for hypothermia - this is the very dangerous and also important phase of survival which is a result of cold water immersion. In ~ this point, you have to seek trained clinical treatment immediately. Symptom of hypothermia may include intense shivering, loss of coordination, mental confusion, cold and also blue (cyanotic) skin, weak pulse, untreated breathing, rarely often rare heartbeat, and also enlarged pupils. As soon as shivering stops, core body temperature starts to fall critically. Try to protect against body cooling and get the victim to a clinical facility immediately.

Gently relocate the victim to a warmth shelter. Inspect for breathing and also a heartbeat. Start CPR if necessary. If you have dry clothes or a blanket, eliminate the victim"s wet clothes. Usage a minimum of body movement, because rough handling can reason cardiac arrest. Cut the apparel off, if necessary.

NEVER provide a hypothermic person alcohol. Alcohol dilates (opens) your veins, which will certainly make the body shed heat much more rapidly. Also, execute not give food or drink to unconscious victims. Carry out NOT apply heat come the arms and legs. This forces cold blood indigenous the arms and also legs earlier toward the heart, lungs and also brain, lowering core body temperature and causing "after drop" which have the right to be fatal. Do NOT massage the victim or offer the victim a hot bath. Cardiac arrest is a frequent result of hypothermia, and also moving the victim around can it is in a catalyst for this condition.
