Understanding Frostbite

Understanding Frostbite Often a false threat in the open because it has a tendency to run over us, Frostbite is defined as the current freezing of human tissues. It's usually a combination of low temperatures (below freezing temperatures must), wind and humidity. It occurs most commonly in the feet, or more precisely their toes because of cold, wet feet in boots narrow (for example, poor circulation). Some of the other common sites are exposed ends of the ears, nose and forehead. It may happen in the hands and fingers, but not as often thought, because of our ability, our hands just in a more environmentally friendly. Even if your fingers are like the tip with a limited edition and mass, the hands are vulnerable to contact and flash, as the prolonged frost exposure.There are 3 main causes of frostbite1. Prolonged exposure (the most common cause): This is what is traditionally thought and it was prolonged exposure to low temperatures, hence the name. In general, wind and water are also factors equation.2. Direct contact: This is when the skin cold, the metal contacts and a contact is blocked. The film was' fun with this, for example, if a person decides to some of their language on a pole and sticks.3. Flash Frostbite (the nastiest up): This occurs when you spill fuel on the skin to cold temperatures below zero. We have developed chemical fuels do not freeze, so that we can work with them to temperatures below zero. The only drawback is that, if paid on the skin, which is literally eating through the skin.There are 3 types of frostbite1. Surface: Known as frostnip, is when the first layer of skin is blocked and it is very similar to that of a superficial bus and scalding. The skin becomes red and may peel.2. Thickness as a TRUE partial freezing when the skin is often white, waxy and moldy, it is the first of two layers of skin. If you press on the skin and can dent Dent will linger. When heated again this type of frostbite often Blebs, a fluid-filled bladder, which the authorities, such as the fight against dehydration. Note: If the blebs are clearly damage is minimal, if it is dark serious tissue damage and the loss is very likely.3. Full Force: This form of freezing is when all three layers of skin and muscles and bones. Often characterized by a wood or waste esteem and colorless, in the form of severe frostbite amputation is very likely.So how we treat frostbite? Since frostbite is the actual freezing of tissues, what happens is crystals forming in the fluid between cells, which are the cells from the liquid and then dries them. As part of the body re-heated the crystals then evaporate to vasoconstriction and further dehydration. There are crystals, we do not want to rub frozen parts of the body, not to cut and dice or damage inteally.For frostnip one of the best ways to re-heat the skin to skin contact. This could be your hands over your ears, your fingers in your armpits or feet on someone abdomen (not the proposal to make it easier). For partial thickness flux freezing is the best method is to water from frozen in 100 to 105 degrees until the water is complete thawing. Soaking helps to minimize the damage caused by dehydration. Thawing is complete when the color and feeling. The skin usually look red and often form blebs. Note: keep the temperature constant is important, difficult, but with a body frozen in water, so that your best.For full thickness freeze thawing can be done in the same way that partial thickness. This is a very painful process, and we must be careful not to allow the person thawed body part, a doctor has checked out. E 'again a bad job, they completely destroy the tissue and ensures amputation. The idea of the medical community to isolate and keep frozen until you can properly deal with the possibility of refreezing.So How can we prevent freezing? As the saying goes, prevention is the best medicine, so that here? Saturday good list to remember: 1 Use the buddy system. Do you have a friend is an eye for any signs of frostbite.2. Wear appropriate clothing cold, rain and wind, including equipment, footwear and boots.3. Avoid tight fitting clothes that constrict the flow of blood, especially boots.4. Monitor feet for moisture.5. Stay hydrated and calories to maintain order and proper metabolic function circulation.6. Decline of tobacco, increases the possibility of frostbite.7. Avoid contact with combustible metals or cold by wearing gloves or gloves when it comes to these items.8. Condition your hands and feet in the cold with a moisturizer. Fold dry skin resists freezing skin.About on the author: Greg Rouse has been teaching wildeess sports and emergency management in university and college level for more than a decade.
