From 25 to 35% of people live at least once in a faint, with the most prone to swallowing of adolescents and the elderly. What are the causes of fainting.

Fainting, or syncope, is a sudden short-term (up to 4-5 minutes) loss of consciousness, the cause of which is the lack of blood flow to the brain. In other words, fainting is a mild form of acute vascular cerebral insufficiency. This is due to a drop in vascular tone in diseases of the cardiovascular system and blood loss. Various external influences such as pain, fear, anxiety, rapid transition from horizontal to vertical, and breath indoors can also cause short-term anemia of the brain and cause fainter.

Lipotymia: Causes of Fainting

This most mild degree of fecundity - a kind of forward consciousness - occurs in humans, for example, in the delivery of blood or in the case of prolonged stay in a stuffy room. First, there is a state of mild blurred consciousness, dizziness, ringing in the ears, yawning. In addition, lipotamy accompanied by blanche of the skin, hands and feet become cold, serving drops of sweat on the face. These symptoms are precursors of fainter and give you the opportunity to prepare and avoid injuries in the sudden fall.

What to do with lipotyemia

Put the patient on the back (in light cases, you can just plant with support on the back), with the head should be on the same level with the case. If everything happens indoors, then open the window, unfasten the patient's collar, thus ensuring good access to oxygen (most often it leads to a cessation of fainting). If the patient is in consciousness, calm him: fear and a panic sensation can provoke spasm of the cerebral arteries, which will only aggravate cerebral ischemia and reduce its blood supply.

Simple Fuzziness: Causes

Normal fatigue lasts no more than 4-5 minutes, after which a quick and complete recovery of consciousness occurs. Like lipoemia, simple fainting begins with mild blurredness, then there comes a complete loss of consciousness with a muted muscle tone: the patient slowly precipitates (unconscious). In this state, it is difficult for a patient to differentiate the pulse due to low blood pressure and loss of vascular tone. Breathing is superficial, the observer may seem that a person suddenly died.

What to do with simple fainting

A unconscious person does not need to jerk, try to raise or bring to mind. As soon as normal blood supply to the brain is restored, consciousness will return.

As the tone of the vessels is sharply reduced, the elevated head or body will not allow enough blood to enter the brain, which is why the person who has fallen into faeces needs a horizontal position of the body.

The patient can smell a cotton swab soaked with ammonia. The ammonia solution does not restore the cerebral circulation, but it stimulates the respiratory center through nerve endings in the nasopharynx: a person makes a reflex deep breath, and a large portion of oxygen enters the body.

Risk and safety

The possibility of repetition of fainting and associated with the fall of injuries - a security issue that worries any "unconscious" patient. Obviously, only the establishment of a cause can prevent the development of nearsightedness and injuries.

The issue of preventing further fuzziness becomes even more serious when it comes to a person who according to his profession is responsible for the life of other people, such as a driver, pilot or dispatcher. This is why it is extremely necessary to be examined in connection with fainting - it is necessary both to establish their cause and prevention, and to save lives.

The consciousness of consciousness should be the most serious, as some of them may be caused by heart disease.
