Application

1. GENERAL PROVISIONS

1.1. First aid is the simplest measures necessary to preserve the health and save the life of a person who has suffered a sudden illness or injury.

The rescue of the victim in most cases depends on how quickly and correctly the first aid will be provided.

1.2. The essence of first aid is to stop the impact of traumatic factors, to carry out the simplest medical measures and to ensure the speedy transportation of the victim to a medical institution.

1.3. For correct setting First aid work must comply with the following conditions:

(01) in each work shift special persons responsible for the condition and systematic replenishment of first aid supplies and devices stored in first aid kits should be allocated;

(02) in each work shift, people capable of providing first aid should be identified and trained;

(03) care provided by a non-specialist should only be care provided before a doctor, and not instead of a doctor, and should include the following: temporary control of bleeding, dressing of a wound (burn), immobilization (immovable fixation) for severe injuries, resuscitation measures ( artificial respiration, closed heart massage), the issuance of painkillers and other drugs for well-known diseases, the transfer and transportation of victims;

(04) the first aid kit must contain all the necessary medical equipment (according to the packaging manual) for first aid.

1.4. Signs of life and death of a person.

1.4.1. Signs of life:

(01) heartbeat; the assisting person determines with his hand or by putting his ear (by ear) below the left nipple of the victim's chest;

(02) the pulse is determined on the inside of the forearm, on the neck;

(03) the presence of breathing is established by the movements of the chest, by moistening the mirror attached to the nose of the victim, or by the movement of cotton brought to the nasal openings;

(04) pupil reaction to light. When a beam of light is directed, a sharp narrowing of the pupil occurs.

Signs of life are unmistakable proof that immediate assistance can still save a person.

1.4.2. Signs of death:

(01) human death consists of two phases: clinical and biological.

Clinical death lasts 5 - 7 minutes. A person does not breathe, there is no heartbeat, but there are still no irreversible changes in the tissues of the body. During this period, the body can still be revived.

After 8 - 10 minutes, biological death occurs. In this phase, it is no longer possible to save the victim's life (due to irreversible changes in vital organs: the brain, heart, lungs);

(02) distinguish between doubtful signs of death and obvious cadaveric signs.

Doubtful signs of death: the victim is not breathing; heartbeat is not determined; there is no reaction to a needle prick of a skin area; the reaction of the pupils to strong light is negative (the pupil does not narrow).

Explicit cadaveric signs: clouding of the cornea and its drying; when squeezing the eye from the sides with fingers, the pupil narrows and resembles a cat's eye; rigor mortis (starts from the head 1 to 4 hours after death); body cooling; cadaveric spots (resulting from the flow of blood into the lower parts of the body).

2. METHODS OF REANIMATION (RESTORATION) OF VICTIMS IN CLINICAL DEATH

2.1. Carrying out artificial respiration by the mouth-to-mouth or mouth-to-nose method.

2.1.1. Artificial respiration should be performed if the victim does not breathe or breathes with difficulty (rarely, convulsively) or if breathing gradually worsens, regardless of the causes (electric shock, poisoning, drowning, etc.).

2.1.2. You should not continue to do artificial respiration after the appearance of independent.

2.1.3. When starting artificial respiration, the assisting person must:

(01) if possible, lay the casualty on their back;

(02) release the victim from clothing restricting breathing (remove the scarf, unbutton the collar, trouser belt, etc.);

(03) free the victim's mouth from foreign objects;

(04) with the mouth tightly clenched, open it, push the lower jaw forward, doing this so that the lower teeth are in front of the upper ones (as shown in the figure - here and further figures are not shown). If it is not possible to open the mouth in this way, then carefully insert a board, a metal plate or a spoon handle, etc. between the back molars (at the corner of the mouth). and unclench your teeth;

(05) stand on the side of the victim's head, slip one hand under the neck, and with the palm of the other hand press on the forehead, tilting the head back as much as possible;

(06) lean towards the victim's face, take a deep breath with an open mouth, completely tightly cover the victim's open mouth with his lips and exhale vigorously (at the same time covering the victim's nose with his cheek or fingers). Air can be blown through gauze, a scarf, a special device "air duct", etc.

With tightly clenched jaws of the victim, it is necessary to take measures according to paragraph , subparagraph (04), because. artificial respiration by the mouth-to-nose method is carried out with the victim's mouth open;

(07) in the absence of spontaneous breathing and the presence of a pulse, artificial respiration can be performed in the "sitting" or "vertical" position (on a support, on a mast, etc.);

(08) observe the second interval between artificial breaths (the time of each breath of air is 1.5 - 2 s);

(09) after restoration of spontaneous breathing in the victim (visually determined by the expansion of the chest), stop artificial respiration and put the victim in a stable lateral position (turning the head, torso and shoulders is carried out simultaneously).

2.2. External cardiac massage.

2.2.1. External cardiac massage is performed during cardiac arrest, characterized by:

(01) pallor or cyanosis of the skin;

(02) absence of a pulse in the carotid arteries;

(03) loss of consciousness;

(04) cessation or disturbance of breathing (convulsive breaths).

2.2.2. Conductive external heart massage is required to:

(01) lay the victim on a flat, hard base (floor, bench, etc.);

(02) position yourself at the side of the victim and (if one person is assisting) make two quick, vigorous blows in the mouth-to-mouth or mouth-to-nose manner;

(03) put the palm of one hand (usually the left) on the lower half of the sternum (stepping back 3 transverse fingers above its lower edge). Put the palm of the second hand on top of the first. The fingers do not touch the surface of the body of the victim;

(04) press with quick jerks (arms are straightened at the elbow joints) on the sternum, shifting it strictly vertically down by 4-5 cm, with a pressure duration of no more than 0.5 seconds. and with an interval of pressing no more than 0.5 s;

(05) for every 2 deep breaths, perform 15 chest compressions (with one person assisting);

(06) with the participation of two people in resuscitation, carry out the "breathing-massage" ratio as 1:5 (ie, after deep inhalation, carry out five pressures on the chest);

(07) when performing resuscitation by one person every 2 minutes, interrupt the heart massage for 2 - 3 seconds and check the pulse on the victim's carotid artery;

(08) when a pulse appears, stop external cardiac massage and continue artificial respiration until spontaneous breathing appears.

3. FIRST AID FOR WOUNDS

3.1. A wound is a damage to the integrity of the skin, mucous membrane or organ.

3.2. The first aid provider must remember that:

(01) help should be provided with cleanly washed hands with soap or, if this cannot be done, lubricate the fingers with iodine tincture. Touching the wound itself, even with washed hands, is prohibited;

(02) Do not wash the wound with water or medicines, fill it with iodine or alcohol, cover with powder, cover with ointments, put cotton wool directly on the wound. All of the above can interfere with wound healing, bringing dirt from the surface of the skin, thereby causing its subsequent suppuration;

(03) do not remove blood clots, foreign bodies from the wound (because this can cause bleeding);

(04) in no case should any tissues or organs protruding outwards be pressed into the inside of the wound - they must be covered from above with clean gauze;
