First aid measures for electric shock and lightning strike

When lightning strikes, people are easily struck by lightning under trees or buildings. Lightning strikes and electric shocks can be immediately fatal, and minor injuries. An AC voltage exceeding 65 volts will harm the human body, and the high-voltage wire will fall on the ground, and it will cause electric shock within 10 meters of the surrounding area. The voltage of lightning can reach 100 million volts, hitting the human body, can make people immediately carbonized black.

First aid for those who get an electric shock should be contested every second. The patients who suffer from respiratory and cardiac arrest are very critically ill. At this time, they should be rescued and contacted urgently, and the patient should be sent to the nearest hospital for further treatment. Rescue work cannot be interrupted on the way to the patient.

1. Turn off the power switch, cut off the power, and rescue. When the power cannot be turned off, you can use wooden sticks, bamboo poles, etc. to lift the wires away from the body of the electric shock. If you can't pick up the wires or other electric appliances that cause electric shock, use a dry rope to cover the electric shock person and drag them away from the current. Rescuers should wear rubber gloves and rubber sneakers. Never pull the electric shock with your hand, and you cannot forget your own safety because you are saving people.

2. If the injured person is conscious and his breathing and heartbeat are autonomous, the injured person should be allowed to lie on the spot and observe closely. Do not stand or walk temporarily to prevent secondary shock or heart failure.

3. Call the ambulance immediately when the injured lose consciousness, and try to wake up the injured

4. If you find that your heartbeat breathing has stopped, you should immediately take resuscitation measures such as mouth-to-mouth artificial respiration and chest heart massage (except for a few who have been confirmed to be electrocuted). The general rescue time should not be less than 60-90 minutes. Until the person who got an electric shock resumed breathing, heartbeat, or was diagnosed with no hope of survival. On-site rescue can allow two persons to perform mouth-to-mouth artificial respiration and chest compressions, respectively, at a ratio of 1:5, that is, 1 artificial respiration and 5 cardiac compressions. If only one person was rescued at the scene, the chest compressions and artificial respiration were performed at a ratio of 15:2. That is, the chest compressions were performed 15 times first, and then the mouth-to-mouth artificial respiration was repeated twice. .

note:

1. When handling electric shock injuries, attention should be paid to other injuries. Such as bounce off the power source after an electric shock or fall from high altitude, often complicated with craniocerebral trauma, blood pneumothorax, visceral rupture, limb and pelvic fractures.

2. During the on-site rescue, do not move the casualty at will. If you do need to move, the rescue interruption time should not exceed 30 seconds. Move the injured person or take him to the hospital. Except that the injured person should lie flat on a stretcher with a flat hard plank on the back. Rescue should be continued. Those who have stopped breathing should continue artificial respiration and chest compressions. The treatment cannot be suspended without succession.

3. Do not apply ointment or unclean dressing to wounds or wounds with electric burn, but use clean dressing to wrap or send to hospital for doctor treatment.

4. When you encounter lightning and thunder, you should quickly evade the nearest building. When there is nowhere to hide in the wild, take off metal objects such as watches and glasses, find a low-lying place and lie down, and do not hide under a big tree. Do not stand on high walls, under trees, near electric poles or near antennas.
