Information on prevention of drowning
During the summer vacation, many students like to travel together, especially because of the hot weather, everyone is willing to play and swim by the water, and often at this time, it is easy to have dangerous situations. In order to prevent drowning accidents, I have compiled the safety education materials for preventing drowning as follows:
Drowned
1, cause of death by drowning
It is mainly due to the inhalation of a large amount of water in the trachea that hinders breathing, or because of the strong spasm of the larynx and the closure of the respiratory tract.
2. Symptoms
The drowning person's face is bruised, his eyes are bloodshot, and his mouth, nostrils and trachea are full of blood bubbles. Cold limbs, weak pulse, even convulsions or respiratory heartbeat stop.
3. Self-help and mutual aid
When drowning happens, if you are unfamiliar with the water, you can take the method of self-help: in addition to calling for help, take a supine position and tilt your head back so that your nose can breathe out of the water. Shallow exhalation and deep inhalation. Because when inhaling deeply, the body specific gravity drops to 0.967, which is slightly lighter than water, and can surface (when exhaling, the body specific gravity is 1.057, which is slightly heavier than water), so don't panic at this time, and don't raise your arm and flap it left and right to make your body sink faster.
Swimmers, if they have cramps in their calves, should keep calm, take a backstroke posture, bend the toes of the cramped legs backwards with their hands to release the cramps, and then slowly swim to the shore.
To rescue the drowning man, swim to the vicinity of the drowning man quickly, observe the position clearly and rescue him from the rear. Or throw boards, lifebuoys, long poles, etc. So that the drowning person can climb ashore.
After the water rescue:
First clean up the silt and sputum in the mouth and nose of the drowning person, take off the false teeth, and then control the water. The rescuer bends his knees on one leg and puts the drowning person on his thigh, so that the water in the drowning person can be discharged from the trachea and mouth by body position. In some rural areas, the drowning person will lie on the back of the cow, with his head and feet suspended, driving the cow to walk, thus controlling water and playing the role of artificial respiration. If the drowning person's breathing and heartbeat have stopped, give mouth-to-mouth artificial respiration immediately and massage the chest at the same time.
How to prevent drowning
Swimming is one of teenagers' favorite sports. However, if you are not prepared, lack safety awareness, panic when you encounter an accident, and you can't save yourself calmly, it is easy to cause drowning casualties. In order to ensure the safety of swimming and prevent drowning accidents, the following must be done:
1, don't go swimming alone, let alone in places where you don't know the bottom and water conditions, or dangerous places where drowning casualties are likely to occur. Choosing a good swimming place requires a clear understanding of the environment of the place, such as whether the reservoir and bathing place are sanitary, whether the water surface is flat, whether there are reefs, undercurrents, weeds and the depth of water.
You must be organized and swim under the guidance of a teacher or someone familiar with water. Take care of each other. If a collective organization goes swimming, it is necessary to count the number of people before and after launching and designate lifeguards for safety protection.
Pay attention to your health. People who are prone to cramps in limbs should not take part in swimming or swim in deep water. Get ready before you go into the water and exercise first. If the water temperature is too low, wash your body with shallow water first, and then go swimming after getting used to the water temperature. Students with dentures should take them off to prevent them from falling into the esophagus or trachea when choking.
4. Be self-aware of your own water quality, don't be brave after entering the water, don't dive and snorkel rashly, and don't fight with each other to avoid drowning. Don't swim in rapids and whirlpools, let alone drink and swim.
5. If you suddenly feel unwell during swimming, such as dizziness, nausea, palpitation, shortness of breath and so on. , should immediately go ashore to rest or call for help.
6, in swimming, if the calf or leg cramps, don't panic, you can kick or jump hard, or massage hard, strain the cramp, and call for help to your partner.
7. When a drowning accident occurs in swimming, the first aid on the spot is urgent, and cardiopulmonary resuscitation is the most important. After the drowning person is rescued ashore, the vomit, sediment and other impurities in the oral cavity and nasopharyngeal cavity should be removed immediately to keep breathing smooth; The tongue should be pulled out to avoid backward turning and blocking the respiratory tract; Raise the belly of the drowning person, make his chest and head droop, or hold his legs, put his belly on the rescuer's shoulder, and do the action of walking or jumping to "pour water". Restoring the drowning person's breathing is the key to the success of first aid. Artificial respiration should be carried out immediately, and mouth-to-mouth or mouth-to-mouth artificial respiration can be used. At the same time of first aid, you should be sent to the hospital for treatment quickly.
How did you save yourself from drowning?
During the summer vacation, many students like to travel together, especially because of the hot weather, everyone is willing to play and swim by the water, and often at this time, it is easy to have dangerous situations. Over the years, students' drowning incidents have occurred from time to time, some of which are caused by students not mastering scientific rescue skills when helping each other. In fact, in our daily life, drowning accidents happen from time to time. What should we do if we meet a drowning person?
When someone falls into the water, rescuers should not rush to save people, because it will be very dangerous if they are caught by the drowning person. Entanglement with the drowning person in the water will not only consume a lot of physical strength of the rescuer, but sometimes even lead to exhaustion of physical strength of the rescuer and eventually death. If the situation is very urgent at that time, and the rescuer has certain rescue skills, then the rescuer should take off his clothes and shoes as soon as possible before entering the water, and try to avoid being caught by the drowning person when approaching.
