"First aid for bleeding" - Sample: Internal bleeding. There are three types of bleeding: capillary, venous and arterial. Arterial bleeding and first aid. First aid for bleeding. The limb must be elevated. Ways to stop bleeding. Signs of internal bleeding: - paleness, weakness, dizziness, cold sweat.
"Wounds and bleeding" - With bullet wounds, the inlet is smaller than the outlet. Bullet wounds predominate among gunshot wounds; splinters are less often noted. The outpouring of blood from a blood vessel is called bleeding. Facial injuries. Classification of bleeding. Soft tissue injuries to the scalp are always dangerous.
"First aid for injuries" - Trauma of the pelvic region. If the victim is not breathing, start resuscitation. If you are forced to transport the victim yourself, call several helpers. It is UNACCEPTABLE to put splints on the legs if the victim is lying in the "frog" position. Injury of the spine, back. First aid for injuries of the pelvic region, spine, back.

Fundamentals of medical knowledge and first aid rules.
Subject: First aid for wounds.
Injury (from the Greek trauma - wound) is damage to the tissues of the human body with a violation of their integrity and functions, caused by external (mainly mechanical, thermal) influence. Wound (open damage) is a violation of the integrity of the skin, mucous membranes with damage to various tissues and organs, caused by mechanical action.
Shallow wounds with damage to only the superficial layers of the skin or mucous membrane, caused by a flat object over a large area, are called abrasions , and superficial damage caused by a sharp object in the form of a thin line - scratches .
According to the mechanism of wounding, the nature of the injuring object and the volume of tissue destruction, there are:
cut
chopped
bitten
firearms
At venous bleeding, dark blood flows out slowly, evenly, in an indirect stream.
At capillary bleeding, blood oozes drops from the entire wound surface.
Capillary and venous bleeding is stopped by applying a pressure sterile bandage. In case of venous bleeding, the damaged surface should be raised.
When providing first aid at the site of injury, it is necessary to stop the bleeding. When treating wounds, care must be taken asepsis And antiseptics .
Asepsis - This is a method that ensures the prevention of microbes entering the wound during its treatment. When treating wounds, the basic law of asepsis must be observed: everything that comes into contact with the wound must be sterile.
Antiseptics implies a set of measures aimed at the destruction of microbes on the skin, in a wound or in the body (as a whole).
When providing first aid for injuries and wounds, taking into account their severity and characteristics, a certain sequence of first aid measures can be distinguished:
For all types of injuries, it is necessary to quickly and carefully deliver the victim to the nearest medical institution, and if possible, quickly call a doctor or an ambulance.

Description of the slide:
First aid is the most urgent measures taken by others or by the victim himself to save a person's life and alleviate his suffering until qualified (medical) medical care is provided.
3 slide
Description of the slide:
There are some general rules help you need to learn (memorize): Find out what happened. The type of first aid and the nature of the message to call the doctor depend on this. Protect the victim from further danger or at least reduce it. For example, move to a safe place; in case of a road accident - to fence off the scene, to take the victims out of the burning cabin. At the same time, it is always necessary to think about your own safety: if you don’t save yourself, you won’t help others.
4 slide
Description of the slide:
Immediately start taking first aid measures. For example, applying a pressure bandage to a heavily bleeding wound, gastric lavage. Call as soon as possible ambulance". If you are alone with the victim, try to attract attention with screams, gestures, ask someone to call for help. Stay with the victim until the doctor arrives, try to calm him down, instill a sense of security and faith in a successful cure. Talk to the victim, hold his hands, stroke his head. These simple tricks can prevent the development of life-threatening shock.

Description of the slide:
First aid kit For first aid, you must have an individual first aid kit with you. Going on a hike, on a long trip, picking mushrooms, hunting, cycling, you definitely need to take it with you. The first aid kit should contain a minimum of funds to provide first aid or self-help if necessary. In case of injuries and cuts, you must have: a rubber tourniquet to stop bleeding, sterile bandages and wipes, a bactericidal plaster, a sticky plaster, tincture of iodine, potassium permanganate.
6 slide
Description of the slide:
In case of burns and frostbite, you will need a synthomycin emulsion. The first aid kit should include the simplest medical instruments: scissors and a scalpel. In addition, you need to know some medicinal plants, their healing properties and methods of application. The first aid kit must also contain special preparations. In addition to the medicines that have already been mentioned, the first-aid kit should contain validol (it is placed under the tongue for pain in the heart), analgin, amidopyrine, ammonia, boric acid, petroleum jelly. Universal first aid kits, which are sold in pharmacies, contain special rules for the use of drugs. Be sure to read the rules before using any medicine.

Description of the slide:
FIRST AID FOR CUTS, ARASSES AND BRUSHES Cuts, abrasions and bruises are the most common types of injuries. It is difficult to imagine a person who has never cut himself or seen a bruise on his body. A cut is a violation of the integrity of the skin, which occurs from sharp, cutting objects: a razor, a knife, a piece of ice or glass, a tightly stretched thread, and even a sheet of paper.
8 slide
Description of the slide:
With a deep cut, large vessels and tendons can be damaged. Bleeding from shallow cuts can be profuse, but it is usually not difficult to stop. Press the wound with your finger (through a sterile napkin) for a few minutes, then treat the edges of the wound with a solution of iodine or hydrogen peroxide and apply a bandage.
9 slide
Description of the slide:
The bandage should be tight enough, but not disturbing blood circulation. If the bandage is wet with blood, then do not remove the bandage, but bandage a new one over it. A shallow cut can be sealed with a bactericidal adhesive plaster, which is best removed at night, since a wound free from a bandage heals faster.
10 slide
Description of the slide:
An abrasion occurs from contact of the skin with an uneven, hard surface. Abrasions are usually contaminated, they often contain foreign particles. Therefore, they must be washed with plenty of soap and water, treated with iodine solution, hydrogen peroxide or other disinfecting liquid. If the abrasion is extensive and bleeding, it must be covered with a bandage.
11 slide
Description of the slide:
Remember: help should be provided with clean hands! Wash your hands with soap, treat them with alcohol. Be careful not to let the victim's blood get on your cuts and scrapes. This is necessary for your own safety, since there are diseases that are transmitted through the blood (human immunodeficiency virus - HIV infection). Wash your hands again with soap and water after helping. Bruises are another common type of injury. They occur when dropped or hit with a blunt object. Usually the skin is not damaged. A bruise is manifested by a bruise or hemorrhage. Blood from ruptured small vessels impregnates the underlying tissues, and a blue-purple spot appears on the skin. Over time, this spot becomes a greenish-yellow color, after a few days it disappears completely. The bruise usually does not require treatment, it is enough to apply ice (through a tissue) or a cold compress for 15 minutes. This will reduce swelling and spread of the bruise.
12 slide
Description of the slide:
A rupture of a larger vessel leads to the formation of a hematoma - this is an outpouring and accumulation of blood under the skin and in the muscles. There is noticeable swelling, bruising, pain. First aid consists of applying a bandage and applying a cold compress or ice. The bandage will tighten the damaged vessels and reduce the outpouring of blood. special attention deserve a head injury. They are very dangerous and can have dire consequences. A person with a head injury should move less for a while and be monitored. The same applies to someone who has received a strong blow to the stomach or chest. In these cases, damage may internal organs.
13 slide
Description of the slide:
Remember: a deep wound, a dislocation, a large hematoma, loss of consciousness or drowsiness, a headache, a clear liquid from the ear or nose, an unreasonable bruise on the body almost always require qualified medical assistance. Therefore, it is necessary to take all possible measures to deliver the victim to the doctor.
14 slide
Description of the slide:
If you hurt a friend! Any damage to the skin is considered a wound. It is difficult to imagine a person who has never cut himself or seen a bruise on his body. Rubbish, you say. Judging in this way, you will be greatly mistaken ... Any, even a minor injury, always carries two big dangers: 1. Due to a violation of the integrity of the skin, there is a danger of the introduction and reproduction of pathogenic microbes in the wound, that is, the danger of infection (infection) - preventing infection of the wound. 2. Bleeding begins. It can be so strong that there is a danger to life due to a large loss of blood - an early stop of bleeding
15 slide
Description of the slide:
On injuring objects (be it a knife, glass, razor, stone) and the surface of the skin there are always millions of different microorganisms. At the moment of injury, along with the injuring object, pyogenic bacteria most often enter the wound, which cause a purulent inflammatory process, which significantly slows down the healing of the wound. When treating wounds with dirty hands or when using contaminated non-sterile dressing material (bandage), if the bandage is applied incorrectly, secondary, additional infection of the wound may occur.
16 slide
Description of the slide:
In addition to pyogenic bacteria, more dangerous microbes can also enter the wound, which cause such formidable diseases as tetanus and gas gangrene. Sometimes a few hours are enough for the development of these diseases (with extensive wounds, exhaustion, cooling of the victim), which means that in such situations it should be taken to a medical facility as soon as possible to provide medical care and administer tetanus and anti-gangrenous sera.
17 slide
Description of the slide:
It's a shame that the cause of misfortune can be not the wound itself, even a severe one, but the frivolous attitude of the victim and the people around him to medical recommendations and cleanliness. Everyone should know for sure: any, even the smallest wound, scratch cannot be left unattended. “Perhaps, I suppose, if you are wounded, drop it!” Sometimes, with wounds, a purulent inflammatory process develops into a general blood poisoning. Such a complication can result in the death of the patient, despite the most intensive treatment.
18 slide
Description of the slide:
Initial treatment of the wound Small wounds, abrasions, scratches, cuts should be lubricated with any available antiseptic (killing germs) agent: solutions of iodine or brilliant green (brilliant green), hydrogen peroxide, which will protect the wound from infection. A shallow cut can be sealed with a bactericidal plaster. Small foreign bodies that have penetrated the skin (splinters, thorns, glass and metal fragments) are removed with tweezers, a needle, then lubricating the wound with an antiseptic.
19 slide
Description of the slide:
Deep or large wounds in the absence of antiseptic agents can be protected by simply applying a sterile dressing (bandage from an individual dressing bag). In this case, you can not touch those layers of the bandage that will be in direct contact with the wound. For dressing, it is best to use an individual dressing bag. It consists of sterile materials: a bat (10 centimeters wide and 7 meters long) and two cotton-gauze pads. For small wounds, the pads are placed one on top of the other; if the wound is large, the pads are placed next to each other. Then tightly bandage the injured area to stop the bleeding, but not too tight - this can interfere with blood circulation.
20 slide
Description of the slide:
In the presence of antiseptics, it is necessary to wipe the skin around the wound 2-3 times with a piece of cotton wool or a bandage moistened with hydrogen peroxide, iodine, you can use gasoline, vodka, trying to remove dirt, earth, and pieces of clothing from the skin surface. This will prevent infection of the wound from the surrounding skin after applying the dressing.
21 slide
Description of the slide:
Remember! When treating wounds, it is impossible to: wash them with water; allow cauterizing antiseptic substances (alcohol, iodine, gasoline) to enter the wound; remove stuck foreign bodies and dirt from deep wounds (this can only be done by a doctor); fill the wound with powders, apply ointment on it, apply cotton wool on its surface; remove sticky, blood-soaked bandages. Just put a new, sterile one on top of it.
22 slide
Description of the slide:
When even a small wound appears, there will definitely be blood. Don't be afraid of it. Blood carries dirt out of the wound that could get there. If the blood oozes weakly, for example, with an abrasion on the knee, then only the capillaries, the smallest blood vessels, are damaged. Such bleeding will soon stop on its own, and a fresh blood crust will form on the surface of the wound. In case of capillary bleeding, having treated the wound with iodine, apply a light bandage of several turns of a bandage, a handkerchief. To reduce bleeding, it is enough to raise the injured limb above the level of the body.
23 slide
Description of the slide:
It also happens that blood of a dark cherry color flows out slowly, evenly and continuously. In this case, the vein was damaged, which is more serious, especially the injury to the veins of the neck and chest. In case of venous bleeding, a tight (pressure) bandage is necessarily applied: several layers of gauze, bandage, a dense ball of cotton wool are applied over the wound and tightly bandaged. After a while, the bleeding should stop. Without delay, the victim must be shown to the doctor.
24 slide
Description of the slide:
It is especially important to stop arterial bleeding when the blood is bright red in color and beats with a strong pulsating stream. This color of the blood and the pulsation of the jet are signs of damage to the artery - the blood vessel in which blood pressure is highest. Because arterial bleeding is usually very intense. Within just a few minutes, blood loss that is incompatible with life can occur. Therefore, with arterial bleeding, you should not waste time determining the type of bleeding and releasing the wound from clothing, but you should, without fear of blood, immediately press the artery with your finger or fist above the wound for a period of time while you yourself or someone around you prepares everything you need for a more reliable way to stop bleeding: pressure bandage, twist, tourniquet.
25 slide

26 slide
Description of the slide:
An adult human body contains an average of 5 liters of blood. The loss of at least 1 liter can lead to a life-threatening state of shock, the loss of 2-2.5 liters is fatal to humans.
27 slide
Description of the slide:
Remember the sequence of actions when stopping severe bleeding of a limb from an artery with a tourniquet: First, press the artery with your finger and give the injured arm or leg an elevated position. A tourniquet - an elastic rubber tube or strip - put on a flat lining (a piece of fabric without folds) to less injure the skin. Apply the tourniquet above the wound and as close as possible to it. In this case, the tourniquet is stretched and encircled 2-3 times with the injured arm or leg. The first turn should be the tightest. The free ends of the tourniquet are tied (fixed with hooks). The correct application of the tourniquet is evidenced by the immediate cessation of bleeding, blanching of the limb. If it is cold outside, the arm (leg) should be wrapped up to prevent frostbite.
28 slide
Description of the slide:
The tourniquet can be applied for no more than 1.5-2 hours. During this time, it is necessary to deliver the victim to a medical facility. If it is not possible to do this within 2 hours, then, having pressed the artery with a finger, the tourniquet must be removed for 10-15 minutes, and then applied again, but slightly lower or higher. Sometimes it is necessary to do this several times (in the summer every hour, in the winter every half hour). It is necessary to attach a note to the tourniquet indicating the exact time of its application. The victim with a tourniquet applied must be in a supine position. If the tourniquet is tightened too tightly or left for a long time, tissue necrosis may begin. The first sign of this is the blueness of the part of the body on which the tourniquet is applied. After stopping the bleeding, it is necessary to treat the surface of the skin adjacent to the wound with iodine and apply a sterile bandage to the wound.

Description of the slide:
A tourniquet from auxiliary means is called a twist. You can use a waist belt, a scarf, a piece of cloth, a shirt sleeve, a bandage. The object used for twisting is freely tied to the right place. Between the fabric (belt) and the limb, they pass an unbreakable stick, a plank and twist it until blood stops flowing from the wound. Then the stick is bandaged to the tourniquet, and the wound is bandaged. It is possible to achieve compression of the artery of the limb by its maximum bending. To do this, under the place of the fold, you need to put a roller of gauze, bandage or cotton wool, then bend the limb with an effort and fix it (you can use a belt) in this position.
31 slide
Description of the slide:
Internal bleeding can be determined by appearance person: he turns pale, covered with sticky cold sweat, the pulse becomes frequent and weak, the stomach is hard. It is urgent to call an ambulance or take the victim to the hospital. The victim should be laid down or given a semi-sitting position. Apply a plastic bag with ice or snow to the intended area of bleeding (stomach, chest, head), wrapping it with a towel, a bottle of cold water. A few words should be said about especially dangerous internal bleeding, when, as a result of an ulcer, a strong blow or a fall from a height, blood enters some cavity (abdominal, chest, skull).
32 slide
Description of the slide:
Nosebleeds The nasal mucosa is very rich in blood vessels, so even with a slight blow or scratch, nosebleeds occur. Outwardly, it looks impressive and much scarier than it really is. So don't be afraid, it's normal. It is useful to know the main causes of nosebleeds: slight bruising of the nose or a blow to the nose; minor damage to its mucous membrane (scratches, abrasions), for example, from picking with a finger;
33 slide
Description of the slide:
fluctuations in atmospheric pressure, air humidity, stuffiness: physical overstrain; binge eating; prolonged exposure to the sun; some diseases.
34 slide
Description of the slide:
The most important thing in any bleeding is to remain calm. Fuss will only increase the bleeding. It is recommended to sit down with your head slightly tilted forward, and let the blood drain - this is not for long. You don't have to tilt your head. It may seem to you that the bleeding has stopped, but by changing the position of the head, you will be convinced of your mistake, but time will be lost. In some people, blood entering the stomach can cause vomiting. With nosebleeds, a cold compress applied to the bridge of the nose helps a lot. For this purpose, a wet handkerchief, and snow from the balcony, and a piece of ice from the refrigerator, wrapped in a clean cloth, are suitable. To stop bleeding, you can also squeeze your nose just above the nostrils under the cartilage for 5-10 minutes.
35 slide
Description of the slide:
With a sufficiently strong nosebleed, use 3% hydrogen peroxide. Insert a cotton or gauze swab moistened with this solution into the nose. After the bleeding stops, remove the swab, but very carefully. Then lie down a bit. During the day after the bleeding, avoid sudden movements, do not sneeze heavily, do not blow your nose, do not lift heavy things, and do not take a hot bath.
36 slide
Description of the slide:
However, there are situations that require increased attention, remember them: if after 15-20 minutes the bleeding does not stop, immediately consult a doctor; if it was caused by a fall or a severe bruise to the head, consult a doctor immediately; if the leaking blood is mixed with a clear liquid, consult a doctor immediately!

Description of the slide:
FIRST AID FOR INJURIES AND FRACTURES OF BONES Nature has taken care of the strength and reliability of our musculoskeletal system. However, this strength also has a limit. When playing sports, hitting, falling, and just a sharp, awkward movement, you can inflict injuries of varying severity on yourself - from sprains to bone fractures.
38 slide
Description of the slide:
There are over 200 bones and over 630 muscles in the adult human body. Together with muscles (skeletal muscles), ligaments, joints, bones make up the musculoskeletal system. Its main tasks are to ensure the movement and maintenance of our body in any position (support function), as well as the protection of internal organs. Bones and ligaments have a large margin of safety. For example, some tendons are able to withstand a load of 270-500 kg. But with a sharp (excessive) movement in the joints, sprain or rupture of the ligaments can occur. This injury can also be combined with a sprain (partial tear) or complete tear of the muscle. In this case, severe pain appears, swelling and bruising form at the site of the injury. Performing the usual movements due to damage to the joint is impossible.
39 slide
Description of the slide:
What should be done if the ligaments are torn or sprained? Give rest to the joint. Apply a tight bandage with a regular or elastic bandage. Apply a cold compress or ice for 20 minutes. Remember: Do not apply ice directly to the skin. An injured arm or leg must be elevated to reduce blood flow to it. Sometimes the restoration of the functions of the damaged ligament is slower than the healing of simple fractures. Moreover, repeated injuries of a once damaged joint are possible.
40 slide
Description of the slide:
Dislocations. With strong flexion in the joint, muscle contraction, impact, fall, the ends of the bones that form the joint can be displaced. If the articular surfaces of the bones completely lose contact with each other and the head of the dislocated bone leaves the joint cavity through a torn capsule, then such a dislocation is called complete. If the bones are partially in contact, then this is an incomplete dislocation. With a dislocation, the victim experiences severe pain. An arm or leg is in an unusual position. Movement in this case is impossible or severely limited.
41 slide
Description of the slide:
The treatment of dislocations consists in repositioning, in which the normal ratios of the bones in the joint are restored. Remember: you can not set the dislocations yourself! When rendering first aid, it is necessary to ensure the immobility of the injured limb.
42 slide
Description of the slide:
To do this, the hand is fixed (tied to the body with a scarf, bandage). A leg with a dislocation in the hip joint is bandaged to a healthy leg. Its immobility can be ensured by tying a stick, ski, umbrella or any other improvised means to it. The position of the dislocated limb should be comfortable, not painful. When dislocating the knee joint, do not try to forcefully bend or straighten the leg. Put your knee in the most comfortable position and fix this position by placing a pillow, clothes under the knee.
43 slide
Description of the slide:
Fractures. A fracture is a complete or partial violation of the integrity of the bone, arising from the impact on the bone of an object. Fractures are complete, when the fragments of the bone are completely separated from each other, and incomplete, in which the integrity of only part of the diameter of the bone is broken. These are cracks and fractures of the bone. Fractures also happen with displacement of fragments and without displacement. Sharp bone fragments can injure the skin. Such fractures are called open. If the skin is intact, the fracture is called a closed fracture. Debris can pinch muscles, nerves, blood vessels, which can lead to paralysis, circulatory disorders and prevent the fusion of debris.

Description of the slide:
With a fracture, a person experiences severe pain - constantly or during movements. With complete fractures, the limb is shortened and twisted in an unusual place, and when the fracture site is felt, a crunch of a broken bone is heard. In the first days of the fracture, there may be an increased body temperature (sometimes up to 38 degrees). It is very important to provide first aid in a timely and competent manner. It is necessary to ensure complete immobility of the fracture site (immobilization) in order to ensure the rest of the damaged part, to relieve unnecessary pain.

Description of the slide:
For temporary immobilization, tires are used: standard or improvised, that is, made from any durable material suitable for this purpose - boards, sticks, rods, cardboard, skis, an umbrella. After applying a splint or providing other first aid, the victim with an injury should be taken to a medical facility as soon as possible. Illiterate actions or untimely assistance can lead to serious complications and even death.

Facial injuries
Any injury to the face is always extremely life-threatening. First, they are usually accompanied by significant bleeding. Second, they can cause brain damage. It is also possible to develop a wound infection (first of all, there is a great danger of developing tetanus or rabies - when a wound is bitten by a sick animal), damage to the nerves and ducts of the glands (salivary, lacrimal). In the end, wounding the face entails the formation of rough, disfiguring scars.

Bleeding
The human body tolerates the loss of only 500 ml of blood without any special consequences. The flow of 1000 ml of blood is already becoming dangerous, and the loss of more than 1000 ml of blood threatens human life. If more than 2000 ml of blood is lost, it is possible to save the life of a bled man only if the blood loss is immediately and quickly replenished. Bleeding from a large arterial vessel can lead to death in just a few minutes. Therefore, any bleeding should be stopped as soon as possible and reliably.
