First aid for loss of consciousness
The most common causes of loss of consciousness – fainting and traumatic brain injury.
FROZEN – a sudden short-term loss of consciousness caused by insufficient supply of blood to the brain. Om can occur even in physically strong and balanced people weakened by intoxication, malnutrition, lack of sleep, overwork. Sometimes the cause of fainting can be prolonged stationary standing or abrupt transition to a vertical position after staying in bed for several days. In some cases, loss of consciousness is caused by a lack of oxygen in the inhaled air (for example, in high altitude conditions). Fainting can cause severe pain, emotional stress (conflict, the type of blood), the use of vasodilator drugs.
Unconscious state is usually preceded by a sharp deterioration of health: weakness increases, nausea, dizziness, noise or ringing in the ears appear. Then the person turns pale, begins to yawn, becomes covered with cold sweat and suddenly loses consciousness. The pupils are dilated, their reaction to light is slowed down, the pulse is weak, breathing is increased, the muscles are relaxed. Consciousness usually recovers quickly.
First aid should be aimed at improving the blood supply to the brain and ensuring free breathing. Unbutton the collar of the victim, free your chest and stomach from their clothes. If the victim is in a stuffy, poorly ventilated room, open a window, turn on the fan, or carry the unconscious into the air. Lay the person so that the legs are raised.
