What is the condition that can damage tissue with cold exposure?

What is the condition that can damage tissue with cold exposure?

Frostbite is damage to skin and tissue caused by exposure to freezing temperatures – typically any temperature below -0.55C (31F). Frostbite can affect any part of your body, but the extremities, such as the hands, feet, ears, nose and lips, are most likely to be affected.

What is cold injury syndrome?

Non-freezing cold injury is a clinical syndrome which occurs as a result of exposure to low temperature over a long time without freezing of tissue fluids. Prolonged pain and a sensory neuropathy may develop on re-warming.

Is a cold induced injury to the tissues?

Cold-induced tissue injuries are typically divided into 2 categories: nonfreezing cold injuries (NFCI) and frostbite. Examples of NFCIs include frostnip, chilblains/pernio, and immersion/trench foot. Of the 2 types of injury, frostbite is the more devastating and requires more aggressive treatment.

What do you call when part of the body is freezing and tissues are damaged and needs to be amputated?

Frostbite happens when part of your body freezes, damaging your skin cells and tissues. Just like ice coating your windshield, your skin becomes hard and white when frostbitten. You can get both hypothermia and frostbite at once, and both are medical emergencies.

What are the 3 categories that cold injuries can be classified into?

Cold injuries are classified into 3 categories: decreased core temperature (hypothermia), freezing injuries of the extremities, and nonfreezing injuries of the extremities. Each scenario and its characteristic condition(s) will be described.

What is a non freezing cold injury?

Nonfreezing cold injury — NFCI is a general term that includes trench foot and its nautical equivalent immersion foot. NFCI involves injury to the soft tissues, nerves, and vasculature of distal extremities from prolonged exposure to wet, cold (but nonfreezing; generally 0 to 15°C or 32 to 59°F) conditions.

Is the mildest form of a freezing cold injury?

Frostnip is the mildest form of a freezing cold injury. It occurs when ear lobes, noses, cheeks, fingers, or toes are exposed to the cold and the top layers of a skin freeze. The skin of the affected area turns paler than the area around it and it may feel pain or stinging, followed by numbness.

Which is the most severe injury in a cold environment?

The most severe cold injury is hypothermia which occurs from excessive loss of body heat and the consequent lowering of the inner core temperature (internal temperature of the body). Hypothermia can be fatal.

What happens to your body when exposed to cold temperatures?

To prevent this, make sure to dress appropriately for cold temps, especially if you have poor blood circulation. Hypothermia means that your body temp has dipped below normal. This is caused by prolonged exposure to cold temperatures. Your body loses heat faster than it can make it. Your thinking and movements slow down, too.

What kind of disease is the common cold?

The common cold, also known simply as a cold, is a viral infectious disease of the upper respiratory tract that primarily affects the nose. The throat, sinuses, and larynx may also be affected.

Which is an injury to the soft tissue?

A contusion (bruise) is an injury to the soft tissue often produced by a blunt force, such as a kick, fall, or blow. The result will be pain, swelling, and discoloration because of bleeding into the tissue.

What kind of injury is caused by cold weather?

Chilblains is a tissue injury that can be confused with frostbite, but is usually not as severe. This injury is caused by exposure to non-freezing cold weather and humidity.

What does cold exposure mean in medical terms?

Cold exposure, sometimes known as cold stress, is the collective name for several conditions that can affect the body when it is exposed to cold temperatures. You can often suffer from cold exposure even when the outside temperature itself is above freezing, especially in wet conditions.

What causes redness and itching when exposed to cold?

Chilblains. Chilblains are caused by the repeated exposure of skin to temperatures just above freezing to as high as 60 degrees F. The cold exposure causes damage to the capillary beds (groups of small blood vessels) in the skin. This damage is permanent and the redness and itching will return with additional exposure.

What happens to the body when exposed to the Cold?

Treatment may include warming methods, medications (to dilate blood vessels, relieve pain and prevent infection) and/or surgery. Frostbite causes damage to the tissue. Frostnip is a mild case of exposure of the skin to cold. The skin may appear pale or bluish-white, and may itch, ache, or feel numb.
