Concepts about ailment

What is dangerous heat stroke? Symptoms and treatment of the disease are associated with excessive overheating, when the air temperature is too high, and the human body is not able to provide normal heat control. Heat stroke come in two forms:

Heat stroke symptoms and treatment

  1. Overheating of the body occurs when active physical loads are placed on it.The disease is observed more often in people whose daily life is associated with sports, when regularly and for a long time you have to perform exhausting monotonous exercises. This form of the disease is also observed in people whose professional activity is associated with heavy physical labor in a room where it is always hot and stuffy, and there is no ventilation.
  2. Another form is classic. It is due to the fact that the temperature during thermal shock in the room or on the street is very high. Most often, this form of the disease affects children or the elderly.

If the victim does not receive first aid, it can really threaten his health. The fact is that a person adapts to any conditions of his environment. When the air temperature rises, the body more actively releases heat. The process of thermoregulation is associated with sweat glands and skin. If their condition is good, perspiration is effective and the body does not overheat. For information: per hour can stand out a liter of sweat.

Heat stroke temperature

A classic heat stroke in an adult or a child occurs when his body is not able to adapt to high temperature mobile.Many persistent diseases of the skin and cardiovascular system prevent normal perspiration. Also, this form of the disease is observed in infants, preschool children and the elderly.

Degree of heat stroke

In order, if necessary, not to wonder what to do with a heatstroke, you need to know his degree for first aid to the victim. The first degree of the disease is observed when there is a forty-degree heat in the street.But man has a stable adaptability to thermoregulation. Its heat transfer is commensurate with the heat load on the body. Heat is removed from the body through the respiratory tract and skin. Human well-being is satisfactory, although there may be complaints of drowsiness, lethargy, unwillingness to make any movements.

Signs of heat stroke

When the air temperature is fifty degrees above zero, a person may well get a heat stroke. Symptoms and treatment of the disease are associated with heat load, as a result of which heat accumulates in the body and the evaporation of moisture is not compensated. The person who received it, there is a partial adaptation to thermoregulation. Body temperature rises to thirty-eight degrees. Pulmonary ventilation is enhanced, the pulse increases. This is the second degree of the disease.

The third degree of heat stroke can be obtained at an ambient temperature of sixty degrees or more, if a person's fitness for thermoregulation is compromised. In this case, the body temperature rises to forty degrees, the pulse increases sharply (up to 160 beats per minute), the skin becomes red and is covered with drops of sweat.The victim has a headache, crushes his temples, his heartbeat quickens, he is tormented by thirst. It may be difficult to move.

Effects of heat stroke

At the last degree, the fourth, a person completely lacks the body's adaptability to thermoregulation. The patient's condition is characterized by a sharp disruption of the cardiovascular, nervous and other systems. The disease may be accompanied by acidosis and renal failure. There is a high probability of pulmonary edema and cerebral hemorrhage in a person who has received a heat stroke.

Symptoms and treatment

  • A person experiences a feeling of stuffiness and weakness.

Not necessarily all signs of heat stroke are observed in one person. After all, their appearance depends on many factors: age, general health, the presence of chronic diseases, temperature and humidity of the environment, the degree of ventilation of the room. But the presence of two or more symptoms of this disease should be alarming. It is better to seek medical help.

With a strong arousal, Dimedrol or Aminazin is administered to the victim, and Sibazon, Seduxen, Phenobarbital, with convulsion. When cardiac activity decreases - Cordiamin, Caffeine, Strofantin. Oxygen, which breathes the patient, it is recommended to mix with carbon dioxide.
