Hypothermia (hypothermia) - a condition that occurs whenthe fall of the body temperature below the normal value (36,6ºS).This body gives more heat than it can generate.
General hypothermia caused by exposure to cold and is characterized by general and local reactions of the organism.
hypothermia When the body can not function properly, it is a violation of all metabolic processes.
most common cause of subcooling is human presence at a low temperature for a long time, especially if this increased air humidity.It promotes the development of hypothermia person a fixed position on the cold ground or metal surfaces.Very quickly, hypothermia occurs when a person is immersed in ice water.
considerably more heat gives the naked human skin, particularly the scalp.This occurs due to evaporation of sweat.
General hypothermia are more prone to small children, the elderly, physically exhausted, forced immobiliz
Depending on the severity of the damage, there are three degrees of the total exposure.
Mild.There comes a fall in total body temperature to 32-34ºS.The victim pale skin covers the body, there is a fever, bluish color of the lips and nasolabial triangle.Due to the jitter of the lips and lower jaw man is hard to say.In some cases slightly increased blood pressure.The victim is able to move independently.With this degree of hypothermia are often frostbite I and II degree of individual body parts.
average degree of hypothermia.It comes with a further decrease in the body temperature to 29-32ºS.Heart rate at the victim falls to 50 beats per minute.However, his skin is cold to the touch, it takes on a bluish tinge.In humans, decreased blood pressure, slowing breathing, somnolence, apathy, indifference to what is happening.It does not respond to external stimuli, speech addressed to him.In this condition a person may appear frostbite even the most severe.It is very important when moderate hypothermia to avoid sleep.During sleep, is produced by a small amount of energy, which may contribute to the lethal outcome of the victim.
Severe general hypothermia.Occurs when the total reduction in body temperature below 31ºS.Thus heart rate drops to 36 beats per minute.The skin and mucous membranes of the victim becoming pronounced bluish hue, face, lips, hands and feet become swollen.In humans, breathing becomes rare, sharply reduced blood pressure.The victim loses consciousness, he often appear cramps.In many cases, a person falls into a coma.In severe hypothermia may be quite serious frostbite.If the victim is not urgent assistance, possibly death.
First aid for supercooling begins with the termination of the impact of cold on the body of the victim.If possible, a person are entered into a warm room.If this is not possible, the victim is placed in a sheltered from the rain and wind place.
Please remove the wet clothing, and wrap him in a dry blanket.Then, the victim, who is in the mind, it is necessary to drink hot tea, milk, water, juice.
In the case of general hypothermia is recommended to take a warm bath.The water temperature in the bath must be constantly rising, but not above 40 ° C.Then the person should be put in a warm bed, and to impose a warm heating pad.When providing first aid in supercooling necessary to note the presence of frostbitten body parts.On such sites impose a sterile, or at least a clean bandage.
If the victim is unconscious, it is important to constantly monitor his breathing and pulse.If not breathing, you must immediately begin artificial respiration in the absence of pulse - to chest compressions.
very important in the provision of first aid in supercooling not make some mistakes, which can lead to negative consequences.Doctors do not recommend giving the victim a coffee or alcoholic beverages.In addition, you can not put it in a hot bath without prior warming.In no case can not rub the skin vigorously with snow, alcohol-containing liquids, oils, to use an open flame to heat.All of these activities contribute to a sharp drop in body temperature.As a result, small capillaries are damaged, there are internal bleeding and other serious complications.
After first aid the victim of hypothermia need to be taken to hospital.Even if his condition is normal, there may be some complications that can diagnose a doctor.
human legs the first to suffer from hypothermia.This is due to the fact that this part of the body have subcutaneous fat that is able to warm up at low temperatures.Furthermore, there is a large area of skin, which gives up its heat to the environment.
supercooled legs contribute to many reasons.One of them may be incorrectly matched shoes - too narrow, very high heels or just uncomfortable while walking.
Another cause of hypothermia of the lower extremities is increased sweating.It promotes moisture feet, and, as a consequence, they are often hypothermia.
Some people hypothermia feet may be due to violation of capillary circulation.Such disturbances may be caused by certain diseases, low blood pressure, constant stress or unbalanced emotional state.
Even mild hypothermia feet can contribute to the development of many diseases - cystitis, bronchitis, sore throat, and many others.Women may be exacerbated many chronic diseases of the reproductive system.
To prevent hypothermia feet need to abandon synthetic socks and tights in favor of products made of cotton and wool.Winter shoes should be 1-2 sizes larger demi-season.In this case, moreover, that it will not close in such footwear remain air layer between foot and shoe.That she keeps warm.
If the legs freeze and begin to lose sensitivity, an urgent need to go to a warm place.Then you need to make vigorous strides 40-50 feet to enhance the blood circulation in them.
Further warming of the feet on the steps similar to the above first aid measures.
