Frostbite will occur almost instantaneously, especially when the skin is moist. Additionally, a blood clot may form along with an accumulation of body fluids, which decreases the local circulation of blood. If the consequent deficiency of blood supply to the affected cells is extreme, tissue decay may result. Also, cooling of the internal organs of the body can disturb normal functioning, producing a dangerous condition known as hypothermia. It is very dangerous to cool the brain or heart to any great extent.
C alm the victim and avoid aggravating the injury.
Do not walk on frostbitten feet. Do not rub or massage the affected parts of the body, or apply medications. Remove victim from the hazard area to prevent further exposure. Remove wet clothing. Cover affected body part with clean dry dressing.
