Sihai network: earthquakes occur frequently in recent years, and their contingency and uncertainty pose a huge threat to the safety of human life and property. On January 12, 2010, a magnitude 7.0 earthquake occurred in Haiti, resulting in as many as 270000 deaths, which is also the biggest threat to human beings in the past decade.
But when the earthquake happens, we learn some necessary survival and first aid knowledge, which can avoid casualties to the maximum extent! Although the disaster caused by the earthquake is irreversible, if each of us can learn more about survival and first aid knowledge, we can seize every minute and second with God through manpower to save people and danger!
When a big earthquake suddenly arrives, if the magnitude is not high at the beginning, people should leave the building complex quickly and disperse to the open field. Those who do not have time to leave the building are often buried or injured by collapsed houses.
According to the data of the Tangshan earthquake in China, some people survived in the buried debris because:
1. No fatal visceral injury;
2. Try to find the way out, find the vent, then find the exit, and quickly get out of the house ruins of nephew's collapse;
3. Do not shout or tumble unnecessarily when you don't hear the excavation sound and voice searching. Panic and shouting will accelerate metabolism, increase oxygen consumption, and inhale a large amount of smoke and dust to cause suffocation.
It can be seen that although the earthquake can not be completely avoided and controlled by human beings at present, as long as we can master the skills of self rescue and mutual rescue, we can minimize the disaster. The summary is as follows:
1. Keep calm in the earthquake. It has been observed that many innocent people are not injured or crushed to death due to the collapse of houses, but are killed in extreme fear due to mental breakdown and loss of hope for survival. This is because shouting at random will speed up metabolism, increase oxygen consumption, reduce physical strength and tolerance; at the same time, shouting will certainly inhale a lot of smoke and dust, which is easy to cause suffocation and increase unnecessary casualties. The correct attitude is to keep calm in any bad environment, analyze the environment, find a way out and wait for rescue.
2. Hemostasis, fixed crush injury and crush injury are common injuries in earthquake. For open wound, bleeding should be stopped first and the affected limb should be raised, and call for help at the same time. Open fracture should not be reduced on site to prevent the tissue from being injured again. Generally, clean gauze is used to cover the wound and simple fixation is performed before operation. Different parts of the fracture were fixed according to different requirements. According to different injuries, the patients were classified and graded and sent to the hospital for further treatment.
3. When dealing with the wound crush injury properly, try to relieve the heavy pressure as soon as possible. In case of a large area of wound, keep the wound clean, bandage the wound with clean gauze, and contact the hospital immediately for diagnosis and treatment in case of suspected tetanus and aerobacterium infection. For large area and severe trauma, oral administration of sugar and salt water can prevent shock.
4. To prevent many disasters caused by fire and earthquake, fire is a common one. In case of fire, you should leave the scene of fire as soon as possible, take off the burning clothes, or cover your body with wet clothes, or roll on the ground, or directly pour water to extinguish the fire. Do not use your hands to put out the fire, or you will burn your hands. Disinfect gauze or clean cloth and send to hospital for further treatment.
5. At the same time, we should prevent tetanus and gas gangrene, bury the body as early as possible, pay attention to the hygiene of food and water, and prevent the great epidemic after the disaster.
