matters needing attention

Frostbite may be accompanied by hypothermia, and the latter should be treated first. Simple frostbite can be treated according to the following methods. The body temperature can be used to warm, but for the frostbite of more than three degrees, the warming time should not be long. Generally, warm water of 30-40 degrees is used to soak the affected area or warm towel is used to compress the affected area. The water temperature should not be high, and the affected area should not be warmed by fire. If the injured area is heated too fast, it will cause severe pain. When the affected area recovers blood color and consciousness, stop recovery, apply frostbite ointment on the injured area, and then wrap the affected area with gauze or soft clothes. Pay special attention not to rub or rub the affected area, and do not pick out blisters. Many people think that wiping the affected area with snow can quickly raise the temperature. In fact, this is a wrong way. The frostbitten part should not be exposed to the cold after treatment. We should pay attention to keeping warm, not to walk with thawed feet.
