When a certain current or electric energy (static electricity) passes through the human body, it will cause injury, dysfunction and even death. This situation is called electric injury, commonly known as electric shock. Lightning strike is also a kind of electric injury. A mild electric shock may cause temporary pallor, slow movement and loss of response to the surrounding environment. Consciously nervous, weak limbs, general weakness. Most people who faint are because of extreme panic. In severe cases, coma, ventricular fibrillation, dilated pupils, respiratory and heartbeat stop and death may occur.
Usually, most of the electric shocks people encounter are 220 volts of civil electricity or 380 volts of industrial electricity, not high-voltage electricity. If you get an electric shock yourself, there is no one nearby to rescue you, so you need to calm down and save yourself. Because in the first few seconds after electric shock, people are in a state of mild electric shock, and people's consciousness has not been lost. Reasonable and orderly judgment and disposal is the key to successful liberation. Electric shock is not as attractive as you usually think. It's just that alternating current will cause muscles to contract constantly, so the phenomenon of grabbing power more and more tightly will appear after electric shock. At this point, the person who gets an electric shock can quickly grasp the insulation layer of the wire with the other hand and pull the wire out of his hand to get rid of the electric shock. If the electric appliance is fixed on the wall when getting an electric shock, you can push the wall with your feet and lean back at the same time to get rid of the power supply with the help of your body's weight and external force. An electric shock victim who can easily extricate himself will generally not have sequelae such as deafness, visual impairment, menstrual disorder and mild personality change.
If someone is found to be electrocuted, as a rescuer, we must race against time and make full use of the existing local conditions at that time to make the electrocuted person quickly leave the power supply. Never pull the electrocuted person directly by hand, which will not only make the electrocuted person act as a conductor again, increase the damage of current, but also threaten the life safety of the rescuer.
The correct rescue method is: first, disconnect the electric shock from the power supply.
1. Turn off the power supply: If you get an electric shock at home, you can quickly cut off the current by unplugging the power socket, turning off the power switch, and pulling the main power switch.
2. Cut off the circuit: If you get an electric shock due to touching the wire scraped from the ground during an outing or construction, you can cut off the wire with a big knife, axe and shovel with a dry wooden handle to interrupt the current.
3. Wire connection: If a person's body is knocked down due to contact with drooping wires, and the wires are closely connected with the body, and the power switch can't be found nearby, the ambulance personnel can stand on a dry wooden board or plastic and connect the wires touching the person's body with dry insulation such as wooden sticks, poles, bamboo poles and walking sticks.
4. Pull away the electrocuted person: If the electrocuted person's hand is closely connected with the wire and cannot be pulled away, a large dry wooden stick can be used to pull the electrocuted person away from the electrocuted place.
People who get an electric shock are often delirious after leaving the power supply, and the rescuer should immediately carry out the next rescue. Loosen the collar and flat belt of the coat that affects breathing, make it lie on your back, tilt your head back, remove foreign bodies from your mouth, take off your dentures, and keep the respiratory tract unobstructed. If it is found that breathing stops and the carotid artery cannot feel the pulse, mouth-to-mouth artificial respiration and chest external heart massage should be carried out immediately, and they should be carried out persistently until the injured person wakes up or has rigor mortis, until the injured person wakes up or has rigor mortis and lividity. In the process of cardiopulmonary resuscitation, we should try our best to get in touch with nearby hospitals in order to strive for better rescue conditions for the wounded. The same first aid measures should be taken for the wounded injured by lightning.
