Therefore, everyone should know how to recognize frostbite, what to do and what to do, you should not. It is important not to waste time and take measures to rescue the victims from cold hands and feet.
How is frostbite
Reducing heat loss - the natural reaction of the body to cold. The body tries to save the vital organs - heart and mind - and all the warm blood leads to the center of the body. At this time, the periphery of the vessels begin to narrow and spasm. Reduced blood flow in the limbs, they begin to cool. Prolonged exposure to cold combined with high humidity in the body irreversible changes occur, the cells begin to fail, to die and there is tissue necrosis. Pale skin and loss of sensation - the first signs of frostbite.
What to do if you become a victim of frost
1. Be sure to remove all wet clothing.
2. With a weak frostbite when skin was white, but there is no damage, help recovery temperature. The victim of course you need to warm up to 37 degrees. This can be done with a light massage with moist gauze.
3. In deep frostbite help warm bath for 30 - 40 minutes. It is warm! Add hot water can be gradual and in any case it is not necessary to pour the boiling water, it only adds injury. After the bath, wipe dry and relax. The first two days is recommended complete rest, and on the third day, you can begin to develop the injured limb.
What you can not do
1. Do not use the traditional methods and do not rub the frozen areas of the body of vodka. The alcohol by evaporation, on the contrary, lowers the temperature of the body and only exacerbates the tissue necrosis. Take alcohol inside is also impossible, you only lose heat.
2. Do not rub the damaged limb snow, oils and ointments.
3. Do not wear tight shoes and tight gloves - they are neither legs nor arms do not get heat. All tight clothing increases the risk of frostbite.
