Application (required). Rules for the provision of first aid to victims

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 the correct setting of first aid work, the following conditions must be met:

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

(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 resuscitation (revival) of victims of 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 caregiver must:

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

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

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

(04) with the mouth tightly closed, 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 - 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 to the side of the victim's head, put 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 in accordance with paragraph 2.1.3, 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 of 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 of the hands 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 injury

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;

(05) do not wrap the wound with insulating tape;

(06) with extensive wounds of the limbs, they must be immobilized (fixed motionless).

3.3. To provide first aid for injuries, you must:

(01) open the individual package in the first aid kit (bag) (according to the instruction printed on its wrapper);

(02) apply a sterile dressing to the wound (without touching the part of the dressing that is applied directly to the wound) and secure it with a bandage;

(03) in the absence of an individual dressing bag, use a clean handkerchief, a clean cloth, etc.;

(04) in the presence of disinfectants (iodine tincture, alcohol, hydrogen peroxide, gasoline), it is necessary to treat the edges of the wound with them;

(05) give the victim painkillers.

3.4. If the wound is contaminated with earth, it is necessary to urgently consult a doctor (for the introduction of tetanus toxoid).

3.5. In case of moderate and severe injuries, it is necessary to deliver the victim to a first-aid post or medical institution.

3.6. In case of penetrating wounds of the chest cavity, it is necessary to transport the victims on a stretcher in the "lying" position with the head part raised or in the "semi-sitting" position.

3.7. With penetrating wounds of the abdomen, it is necessary to transport the victim on a stretcher in the "lying" position.

4. First aid for bleeding

4.1. Bleeding is the outflow of blood from a vessel as a result of an injury or complication of certain diseases.

4.2. There are the following types of bleeding:

(01) capillary - occurs with superficial wounds, blood oozes in tiny droplets. To stop bleeding, it is enough to press a gauze swab to the wounded area or apply a slightly pressure sterile bandage;

(02) venous - blood is dark red, flows out in an even stream;

(03) arterial - blood of a scarlet color, is thrown upwards by a pulsating jet (fountain);

(04) mixed - occurs when both veins and arteries bleed in the wound. This is observed with deep wounds.

4.3. When a vein is injured on a limb, the latter must be lifted up and then a pressure sterile bandage applied.

If it is impossible to stop the bleeding with the above method, you should squeeze the blood vessels below the wound site with your finger, apply a tourniquet, bend the limb in the joint or use a twist.

4.4. Arterial bleeding can be stopped, just like venous bleeding. In case of bleeding from a large artery (with insufficient application of a pressure bandage), it is necessary to apply a tourniquet above the site of bleeding.

4.5. After applying a tourniquet or twist, you must write a note indicating the time of their application and put it in a bandage (under a bandage or tourniquet).

4.6. Keep the applied tourniquet for more than 1,5 - 2,0 hours. is not allowed, because this can lead to necrosis of the bloodless limb.

4.7. If pain occurs from the imposition of a tourniquet, it is necessary for 10-15 minutes. take off. To do this, before removing the tourniquet, they press the artery through which blood flows to the wound with a finger; dissolve the tourniquet should be slow; after 10 - 15 minutes, the tourniquet is applied again.

4.8. After 1 hour, even if the victim can endure the pain from the tourniquet, it should still be removed for 10-15 minutes.

4.9. In case of moderate and severe venous and arterial bleeding, the victims must be taken to a first-aid post or any medical institution.

4.10. In case of nosebleeds, the victim should be seated, put a cold lotion on the bridge of the nose, squeeze the nostrils with your fingers for 4-5 minutes.

If the bleeding does not stop, it is necessary to carefully insert a dense gauze or cotton swab moistened with a 3% hydrogen peroxide solution into the bleeding nostril, leaving the end of the gauze strip (cotton) outside, for which after 2,0 - 2,5 hours you can remove the swab.

If it is impossible to stop the bleeding of the victim, it is necessary to deliver to the first-aid post (in the "sitting" position) or call the medical staff to him.

4.11. First aid for mixed bleeding includes all of the above activities: rest, cold, pressure bandage (tourniquet).

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
