Anti-drowning slogan?

the weather is getting hotter now. Swimming safety has gradually become a hot topic in school safety education.

Rivers, ponds and swimming pools not only bring people joy and enjoyment, but also potential safety crisis. More preparation and sobriety before swimming can bring us laughter and avoid possible regrets.

In the spirit of "people-oriented", in order to ensure the safety of teachers and students and prevent the occurrence of safety accidents caused by swimming, it is forbidden for any students to play and swim in rivers, ponds, swimming pools and other places with water resources without permission, and it is forbidden for students to play and swim in rivers, ponds, swimming pools and other places with water resources at noon and after school. Unless accompanied by parents and other guardians!

so what should we pay attention to when swimming? We collected relevant knowledge. Please listen patiently and you will get something.

1. swimming safety points

1. don't be too hungry or full when you go into the water. You can't go into the water for an hour after meals to avoid cramps;

2. Try the water temperature before entering the water. If the water is too cold, don't enter the water.

3. If you swim in rivers, lakes and seas, you must have a companion, and you cannot swim alone;

4. Observe the environment at the swimming place before launching. If there is a danger warning, you can't swim here.

5. Don't swim in the canyon with unclear geographical environment. The water in these places is different in depth and cold, and there may be obstacles in the water that hurt people, which is very unsafe;

6. Before diving, make sure that the water depth here is at least 3m, and there are no weeds, rocks or other obstacles underwater. It is safer to enter the water with your feet first;

7. When swimming in the sea, swim parallel to the coastline. Those who are not skilled in swimming or have insufficient physical strength should not wade deep. Make a mark on the coast, pay attention to whether you are washed too far, and adjust your direction in time to ensure safety.

Second, how to prevent lower limb cramps during swimming

Warm-up exercises must be done before swimming.

You should consider your physical condition before swimming. If you are too full, too hungry or too tired, don't swim.

Before swimming, you should splash some water on your limbs, and then jump into the water. Don't jump into the water at once.

If you have chest pain during swimming, you can press your chest hard and wait until it is better before going ashore.

If you have abdominal pain, you should go ashore, and you'd better drink some hot drinks or soup to keep your body warm.

Third, the self-rescue strategy of swimming drowning in summer

How to ensure the health and safety of swimming and avoid drowning events? Being unfamiliar with the water situation and rushing into the water can easily lead to life-threatening. In case of an unfortunate drowning incident, experts said that the drowning person should not panic, but should keep calm and actively help himself:

(1) For those with cramps in hands and feet, if they have finger cramps, they can make a fist with their hands, then open them forcibly and do it several times quickly and repeatedly until the cramps are eliminated;

(2) If the calf or toe cramps, first take a breath and float on the water, hold the toe of the cramped limb with the hand on the opposite side of the cramped limb, and pull it hard toward the body, and at the same time press the palm of the same side on the knee of the cramped limb to help the cramped leg straighten;

(3) If you have thigh cramps, you can also solve them by lengthening the cramping muscles.

For drowning people, besides actively saving themselves, we should also actively rescue them on land:

(1) If there are silt, weeds and vomit in the mouth and nose of drowning people, they should be removed first to keep the upper respiratory tract unobstructed;

(2) If the drowning person has drunk a lot of water, the rescuer can kneel on one leg and bend his knees on the other, put the abdomen of the drowning person on the knees, hold the drowning person's head with one hand, press his mouth down with the other hand on his back to discharge the water;

(3) If the drowning person is unconscious, breathing is weak or stops breathing, artificial respiration should be performed after the above treatment. The drowning person can lie on his back, and the rescuer can hold the nose of the drowning person with one hand, hold his chin with the other hand, take a breath, and then blow the air into the mouth of the drowning person with his mouth. After blowing one breath, leave the mouth of the drowning person, release the hand holding the nose at the same time, and press the chest of the drowning person with your hand to help him exhale. This is repeated regularly, about 14-2 times per minute, which can be slightly slower at the beginning and appropriately accelerated later.

Fourth, first aid for drowning

Drowning is a common accident. After drowning, it can cause asphyxia and hypoxia. If the heart stops, it is called "drowning". If the heart does not stop, it is called "near drowning". This classification is of great significance to estimate the condition and prognosis, but the principles of treatment are basically the same, so it is collectively called drowning.

First-aid methods

1. After the injured person is lifted out of the water, the water, mud and dirt in his mouth and nasal cavity should be immediately removed, and the tongue of the injured person should be pulled out of the mouth with a gauze (handkerchief) wrapped around his fingers, and the button and neckline should be unbuttoned to keep the respiratory tract unobstructed. Then, the injured person's waist and abdomen should be picked up to pour water with his back up and his head hanging down. Or pick up the injured person's legs, put his abdomen on the shoulders of the first aider, and run quickly to pour out the accumulated water. Or the first-aid person takes a semi-kneeling position, puts the abdomen of the injured person on the leg of the first-aid person, makes his head droop, and presses his back with his hand to pour water.

2. People who stop breathing should be given artificial respiration immediately, and mouth-to-mouth blowing is generally the best. The first aider is located on the side of the injured person, holding the injured person's jaw, holding the injured person's nostrils, taking a deep breath, slowly blowing into the injured person's mouth, relaxing his nostrils when his chest is slightly raised, and pressing his chest with one hand to help him exhale. Repeatedly and rhythmically (blowing 16 ~ 2 times per minute) until breathing is restored.

3. Patients with cardiac arrest should have chest massage first. Let the casualty lie on his back, with a hard board on his back, his head lowered and his back tilted later. The first aider is located on the side of the casualty. Facing the casualty, his right palm is placed flat on the lower part of his sternum, and his left hand is placed on the back of his right hand. With the help of the body weight of the first aider, he should exert force slowly, but not too hard, so as to prevent fracture. Then he should press down the sternum for about 4 cm, and then loosen his wrist (hands do not leave the sternum) to restore the sternum, and repeat it regularly (6-8

5. What should I do if my ears get water while swimming?

Because water has a certain tension, it forms a barrier after entering the narrow external auditory canal, which divides the external auditory canal into two sections, and because of the gravity of water, there is a secondary pressure between the water barrier and the eardrum, which maintains the balance of pressure on both sides of the water barrier, making it difficult for water to flow out automatically. Sometimes there is a large cerumen obstruction in the external auditory canal, so the water is more likely to be wrapped around the cerumen after entering the ear canal and is not easy to flow out. After water enters the ear, there will be deafness, dizziness and discomfort, so people often want to drain the water very urgently. Some people even use unclean clips, match sticks, small keys, etc., which can break the water barrier and make water flow out, but it is also easy to damage the external auditory canal and even the eardrum, resulting in ear diseases.

The water should be discharged in time after the water enters the ear. The most common methods are:

1. One-legged jumping method: the affected ear is downward, and the gravity of water is used to make the water flow downward from the external auditory canal.

2. Moving external auditory canal method: you can continuously press the tragus with your palm or pull the auricle with your fingers; Or repeatedly opening the mouth and moving the temporomandibular joint can make the skin of the external auditory canal move up and down, left and right, or change the stability of the water barrier and the stability of the pressure, so that water can flow out of the external auditory canal.

3. external auditory canal cleaning method: gently probe into the external auditory canal with a clean cotton swab, and suck out the water once it touches the water barrier.

Because the swimming pool or river water is unclean, the skin and tympanic membrane of the external auditory canal are infected after sewage enters the ear, or the following ear diseases can often be caused by improper treatment after water enters the ear, such as unclean ear digging, etc.: otitis externa, swelling of the external auditory canal, swelling, tympanitis and suppurative otitis media.

If the above symptoms appear after water enters the ear, you should stop swimming temporarily and go to the hospital for examination and symptomatic treatment.
