[publicity and education on drowning prevention II] swimming safety points

First, swimming safety points

1. Don’t be too hungry and full when entering 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 can’t swim alone;

4. Observe the swimming environment 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 3 meters, 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, you should swim parallel to the coastline. Those who are not skilled in swimming or have insufficient physical strength should not wade into the depths. 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 when swimming?

1. Be sure to do warm-up exercises before swimming.

2. You should consider your physical condition before swimming, and don’t swim if you are too full, too hungry or too tired.

3. Dip some water in your limbs before swimming, and then jump into the water. Don’t jump into the water immediately.

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

When you have abdominal pain, you should go ashore, and it is best to drink some hot drinks or hot soup to keep your body warm.

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

How to ensure swimming safety and avoid drowning? 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 and should keep calm and actively save himself:

1. For people with hand and foot cramps, if they have finger cramps, they can make a fist with their hands, then open it forcibly and do it several times quickly 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 the thigh cramps, it can also be solved by lengthening the cramping muscles.

For drowning people, in addition to actively saving themselves, we should also actively carry out land rescue:

1. If there is mud, weeds and vomit in the mouth and nose of the drowning person, it 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 head of the drowning person with one hand, and press his mouth down with the other hand on his back to discharge the water;

3. If the drowning person is in a coma, breathing is weak or stops breathing, artificial respiration should be carried out 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 1420 times per minute, which can be slightly slower at the beginning and appropriately accelerated later.

Fourth, drowning first aid

Drowning is a common accident. After drowning, it can cause ventricular anoxia. For example, it is called "drowning" if the heartbeat stops, and it is called "near drowning" if the heartbeat does not stop. This classification is of great significance to estimate the condition and prognosis, but the treatment principles are basically the same, so it is collectively called drowning.

First aid method

1. After the injured person is carried out of the water, the water, mud and dirt in his mouth and nasal cavity should be removed immediately. Wrap his fingers with gauze (handkerchief) to pull the injured person’s tongue out of the mouth, unbutton the button and neckline to keep the respiratory tract unobstructed, and then pick up the injured person’s waist and abdomen to pour water with his back up and his head drooping. 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 16~20 times per minute) until breathing is restored.

3. People 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. Use the body weight of the first aider to exert force slowly, but not too hard, so as to prevent fracture. Press the sternum down about 4 cm, and then loosen his wrist (hands do not leave the sternum) to restore the sternum, repeatedly and rhythmically (60-80 times per minute).

Due to the tight project schedule, they finally decided to stay in Han to continue their work during the Spring Festival. Tian Songbai said: "The unit keeps people in the post, keeps people in the salary, and keeps people emotionally." Overtime wages are also high, so you can earn more money. When you are not busy with your work, you can take a break and go home to visit the elderly and children. "
On the eve of the Spring Festival, the project department prepared a gift package for the left-behind workers. The couple wrapped the gift package layer by layer and carefully handed it to the courier brother. "It’s nothing for us to eat bitterness. We have to let the two girls at home eat more delicious food." After the New Year’s Eve, the couple dialed the video with the children and saw their daughter’s clever appearance. The couple were both sad and deeply gratified.
The project department distributed the Spring Festival gift package to each left-behind person, and paid the salary and bonus in full and on time before the year.

Li Kaier is here! Finally confirmed the debut time! 46 minutes and 47 minutes! rearguard

China men’s basketball team doesn’t want people. I heard that they can’t beat the passerby?

Jeff, who has no national team task this summer, can play in CBA Summer League with Guangdong team.

On the first day of the game, he turned into a giant. He only rested for two minutes. After playing for 46 minutes, he made 15 of 28 shots, made 9 three-pointers, and scored 47 points, 9 rebounds and 1 assist.

But the team lost to Shanxi team 94-99.

Judging from the appearance time, the number of shots and the number of assists, it is enough to explain the versatility of other players in Guangdong team.

The second couplet was originally a place for practicing young people, but veterans were required to wear game to keep the last underwear, although Jeff was born after 2000.

Young players are still unable to rise, and the future of Guangdong team is really worrying.

Guangzhou team next door beat Tianjin team 93-56, and Rump, who had high hopes, finally went into battle.

But the sense of existence is not strong. After playing for 12 minutes, he made 0 of 2 shots, made 1 of 2 free throws, got 1 point, 2 rebounds, 1 assist, 1 mistake and 1 foul.

Wang Quanze, Jeff and Guo Haowen were once known as the Big Three in China.

Among them, Wang Quanze is considered to be the most promising. He has been playing in American high schools since he was 14 years old. He was ranked 45th in ESPN ESPN2018 National High School Power Forward list.

During his tenure at NCAA, Wang Quanze played for the famous University of Pennsylvania.

He became the main force of the team in his freshman season, averaging 8.5 points, 3.6 rebounds and 1 assist. Match.

Unfortunately, the knee injury in the second season required surgery and reimbursement; The junior year was refunded for the whole season due to the epidemic.

It was not until last year that he finally returned to the NCAA competition.

After graduating from college last year, he officially returned to the Guangzhou team.

He should have made his debut last season, but he underwent knee surgery again in the summer of 22, and refunded the fee in his rookie season.

It was not until the first game of Xia Lian that he started his CBA career.

Although the first game was mediocre, as long as you can play, it is worth celebrating.

Speaking of the naturalized player and active NBA striker Li Kaier, according to China Newsweek, the national team will make its debut at the International Solidarity Cup held in Shenzhen on August 20th.

At that time, the China men’s basketball team will play against the Serbian team.

Li Kaier will continue to compete with this year’s NBA playoff opponent Yue as a player other than the Timberwolves.

Although he won’t make his debut until mid-August, Li Kaier should join the China Men’s Basketball Team at the end of July and train with the team.

After all, everything takes some time to get used to, and it is impossible to put on your shirt and start working.

As the main force of the NBA team, the annual salary is about 10 million dollars, and the strength of Li Kaier is beyond doubt. Most importantly, he is a swingman at the third and fourth positions. He is tall and has long arms. He can play the power forward in China men’s basketball team and play the core role of inside and outside.

He also has good ball control ability, which can solve the shortcoming that our striker has been unable to control the ball.

At least Qiao Shuai is fond of Li Kaier. When the latter came to Shanghai for naturalization some time ago, he personally delivered the training clothes of the China men’s basketball team.

When the two sides met, they began to communicate cordially and talked about music and art, which was almost a phone call on the spot.

It is worth mentioning that Song Xiang, a well-known basketball reporter in China, reported earlier.

In order to play for the China men’s basketball team, Li Kaier even refused the invitation of the American men’s basketball dream team.

Of course, this guy can get along. Such a naturalized player with national identity looks pleasing to the eye and is quite easy to use!
