A person who loses consciousness for some reason lies completely motionless, does not answer any questions, and does not understand what is happening to him. Because at this time, part of the brain "opens" for a certain period of time. However, in this case, the parts of the brain responsible for respiration, blood circulation and various reflexes can function as usual.
It is important to know that some symptoms may occur before fainting, such as dizziness, nausea, tinnitus, sudden weakness, darkening of the eyes, and cold sweats. A person who loses consciousness begins to turn pale, his pulse slows down, and his blood pressure drops. He closes his eyes, loses muscle tone, and loses his balance. At this time it is necessary to provide immediate first aid.
For example:
if you see someone fainting, help them not to hit their head as much as possible;
open room windows if the patient is inside;
Gently lay the patient on the floor so that he is not sitting.
Do not put anything under the head, but it is better to raise the legs as high as possible, which will improve blood circulation to the brain;
try to bring the patient to consciousness by lightly patting him on the face, sprinkling water, or sniffing nectar. You can also use cotton soaked in vinegar;
Check for breathing and pulse; if not breathing and not beating, give artificial respiration and massage the heart area;
"Call an ambulance.
Fainting should not be considered a normal condition. This is because an unconscious person may have irreversible brain activity. It is therefore necessary to try to bring him to consciousness as soon as possible. If the patient does not regain consciousness within 30 minutes, more serious measures are required.
Loss of consciousness usually occurs in the following cases:
when there is a lack of oxygen in the blood;
when concussion;
after severe pain or nervous tension;
extreme fatigue;
severe cooling;
depletion of oxygen in the air;
strong emotional excitement;
dehydration;
head injuries;
severe fear;
severe attacks of liver and kidney disease;
intestinal colic;
sunstroke;
regular numbness after major surgery;
sudden abnormal heart rate;
sudden deterioration of the nervous system;
prolongation of the incidence of infectious diseases;
electric shock or poisoning from something (e.g. chemicals).
