Many people have at least once in their life been in a state of short-term loss of consciousness. This condition is called fainting. The main reason for its onset is the rapid narrowing of the lumen in the blood vessels, which leads to impaired circulation of the brain.
Fainting, the first aid in which should be provided immediately, is a short-term condition that must be distinguished from other urgent conditions of the human body. To do this, you need to know the signs, the main of which are sharp weakness, running flies in front of the eyes, ringing in the ears, the appearance of cold sweat, nausea, shortened, shallow breathing, numbness of the arms and legs. In this case, the skin turns sharply pale, the pulse becomes weak, and therefore it is poorly palpated.
In most cases, fainting, first aid for which has its own characteristics, occurs in weakened people who in the recent past suffered an infectious or other disease. In some cases, the arisen condition can only be a symptom of a complex acute violation of the heart.
In a condition such as fainting, the necessary assistance should be provided immediately. If a person is conscious and says: “I will faint!”, You must put him down, tilting your head forward to increase the flow of blood to the brain. As a result of these actions, more oxygen will enter the brain with blood.
If the patient is unconscious, it is necessary to lay him on his back so that the legs are raised and are at a level above the head. Then weaken the belt and collar, and spray water on the face. If the room is stuffy, be sure to open the window.
In order to bring a person to consciousness and bring out of a condition such as fainting, first aid can be provided as follows. It is enough to bring a piece of cotton soaked in ammonia to the nose. In the event that after the measures taken the person did not wake up, urgently call an ambulance.
Often, fainting is the result of severe fright, excitement, pain. In some people, fear appears at the sight of blood, which leads to loss of consciousness.
From the above it follows that assisting with fainting can be carried out by anyone, even without medical education. A long lack of consciousness can lead to irreversible processes in the brain.
To prevent fainting in hot weather, the following rules must be observed:
• Wear lightweight, breathable clothing, primarily made from natural fabrics. Do not forget to wear hats while in the sun for a long time.
• Try to ventilate the room as often as possible. This event helps to reduce the concentration of carbon dioxide indoors.
Compliance with these rules will exclude the appearance of a condition such as fainting, first aid for which is described above. If it occurs with a certain frequency - this is an occasion to consult a doctor, because in this case, fainting is only a symptom of one of the complex diseases.
