What are the precautions for diving? 1. Corneal injury
Diving will have a great impact on people's eyes. Divers don't wear goggles because they are professionally trained. And inexperienced people, some are out of imitation, some are worried that goggles will fall off, and the result of diving without goggles is corneal damage and astigmatism.
2. Spleen rupture
Divers often pose incorrectly, and their stomachs are prone to water first, which may hurt internal organs and even lead to fatal consequences such as spleen rupture.
3. Cervical spine injury
Most cervical injuries in diving are caused by improper diving. For example, when jumping from the starting platform, the platform is weak, or the entry point is too close, or the hip joint is not straight when stepping on the platform, or the entry angle is too large, or it is hit by a swimmer when entering the water. In addition, the swimming pool water is too shallow (less than 2 meters) is also one of the reasons.
If diving in rivers and lakes, obstacles such as wooden stakes and stones in shallow river bottom or water are the main causes of cervical spine injury. Every summer, when the diving head hits the river bottom or obstacles, it will cause head and neck distortion, leading to cervical fracture and dislocation accidents from time to time.
4, concussion
If the diver's head falls into the pool first, it will cause a serious concussion, and even meet skull fracture's bad luck, which may lead to his death on the spot.
5, cramp cramp
When divers touch the water, due to the great influence of gravity on their bodies, they often encounter spasms and spasms, and a large amount of adrenaline will flow into blood vessels.
6. Casualties
Especially remind swimmers that it is more dangerous for people who swim wild in natural waters to dive. This is because the underwater conditions of rivers, lakes and reservoirs are complicated, and there are many weeds and stones, so diving rashly is easy to cause casualties.
The danger of high-altitude diving is a very thrilling diving sport. Athletes take off from a very high cliff or a specially-made ultra-high platform, complete aerial movements and then enter the water. In the air? Flying? Yes The time is only a few seconds, during which a series of waist twisting and turning movements will be carried out. When it reaches the surface, the speed will be at least 60 miles per hour. When you fall into the pool, you must make sure that your feet come first? Landing? The body must remain absolutely tense and straight. The huge impact force is almost similar to falling on the concrete floor. If you are not careful, the diver may break his skull and die on the spot.
How to prevent diving injuries? 1. For beginners, first of all, we should strengthen safety education, emphasize the technical essentials of diving and entering the water, and don't dive in shallow swimming pools or rivers and lakes with unclear background. Before practicing diving, you must be fully prepared and fully move your limbs, back, head and neck and joints. In addition, when you go into the water to save people or are eager to salvage drowning items, you should take the posture of stepping on the water with your feet, and don't take the diving posture with your head down and your feet high.
2, in the rescue of patients, ambulance personnel should be calm, try to hold the patient's head during the rescue process, don't let it swing, don't let the head and neck bend or stretch, and don't massage at will to prevent nerve damage.
3. Lay the patient flat on the ground. If it is difficult to breathe, the oral contents must be removed immediately to keep the respiratory tract unobstructed, and emergency treatment such as artificial respiration should be given. When transporting patients with cervical spine injury, wooden stretchers should be selected, and the patients should be slowly rolled onto the board by rolling method, and someone should hold the patient's mandible and neck with both hands to keep the cervical spine from being stretched and flexed.
