Скачать или смотреть 4d: Frostbite (2025)

This lesson covers Frostbite. The conditions necessary to cause frostbite are explained. The severity and damage caused by frostbite vary, and how to identify the severity of the damage is detailed. Providing care is discussed, and examples of when it is appropriate to rewarm a frozen extremity are given.

Frostbite a result of exposure to cold and are most common in ears, nose, fingers, and toes. Wind chill increases the risk of frostbite. In severe cases, ice crystals form in the tissues and destroy cells causing permanent damage. In case of frostbite, the skin appears waxy and white and yellow-gray. The frostbite area is cold and numb and may feel like a block of wood. The frostbite tissue is firm and does not move or compress easily when squeezed. However, do not try to rub, squeeze, or slap the affected extremity as this may increase tissue damage.

To care for frostbite, first, get the individual to a warm place, and then call 911/EMS.

Remove any constricting clothing and all jewelry from the affected body part. Remove all wet clothing as well. Redress them in dry, warm clothing and cover them with a heavy blanket.

Put the areas affected by frostbite in warm—not hot—water (the temperature should
be comfortable to the touch for unaffected parts of the body).

Do not rub, squeeze, or slap the affected extremity as this may increase tissue damage. Do not
rewarm a frozen extremity if there is a risk of refreezing.

Seek further care from a health care professional.
