Hypothermia

Hypothermia is a condition in which a person's body temperature drops below normal. Weakened heat transfer or insufficient intake is caused by an individual thermoregulatory feature of the body, in which the body, realizing the decrease in its temperature, loses the ability to adequately and quickly regulate it and does not take measures to increase it. Those. the body retains this ability as a compensatory mechanism due to its additional resources, but lowers its body temperature.

Hypothermia is different, reversible - moderate and irreversible with a risk of death. Hypothermia is also divided into the following types: - pale type (0.25-0.3); - cyanotic type (0.01-0.25); - stupor and coma, if already 3%;

The most common causes of hypothermia are loss of body heat, mechanical trauma, shock, drug use, antidepressants, severe alcohol intoxication, as well as hypothermia, chest compression, and inflammatory processes. Hypothermia occurs when a person is in water at such a temperature that the decrease in the internal temperature of his body to 35 ° C stops without exposure to external heat. The mechanism of development of the process boils down to the fact that the skin, covered with perspiration, is cooled due to evaporation from both the external and internal surfaces; the resulting water droplets reduce the flow of warm air from the alveoli to the skin. However, certain conditions are necessary for the development of the hypothermia stage. When exposed to unfavorable external factors (a wet person in a wet raincoat, swimming in cold water), a person is the first to lose control over the situation. Therefore, primary hypothermia in ordinary people necessarily develops and can only be completed when heat is supplied from the outside (warming).

There are three stages of decreased body temperature: loss of consciousness, confusion and coma. They are divided into hypoxic, obstructive and unbalanced. The outcome of hypothermic conditions directly depends on the amount of fat and the duration of the clinical stage, the presence of respiratory and cardiovascular failure. More pronounced manifestations of hypoxia are accompanied by a long clinical stage, clinical status and the presence of signs of oxygen starvation of the brain. There is also “protein” hypothermia, which occurs when the patient removes blood from the body or during a long stay in a pressure chamber, because Proteins are oxidized by oxygen much more slowly than glucose. A general hypothermic reaction, some pallor of the skin, and respiratory distress appear. It is important to remember that hypothermia poses a serious danger to human life. If you do not help him restore his body temperature in time, then death is possible.

Hypothermia is a condition in which the body's temperature drops below normal. This happens as a result of hypothermia under the influence of low ambient temperatures. The most common causes of heat loss by a person are: staying outside without clothes during the cold season; unsatisfactory technical and sanitary equipment of the tent and sleeping areas; uncomfortable or tight clothing, as well as insufficient clothing. In some cases, a decrease in body temperature can be caused by taking chemical or herbal remedies, such as alcohol, opiates, barbiturates, etc. Characteristic signs of hypothermia are drowsiness and dizziness.

The reasons for the development of hypothermia may be the following: hypothermia, limited consumption of warm food and water, improper use of cold dishes and cold equipment, improper organization of human nutrition, prolonged fasting, exhaustion, low metabolism, mental state, exposure to alcohol. To reduce the influence of these factors, you should follow the rules of personal hygiene and give your body rest. Periods
