What are the key points of first aid for electric shock? Questions on safe use of electricity

The key points of first aid for electric shock are actually two points. The first is to remove the electric shock victim from the power source to prevent the rescuer from being electrocuted (methods include cutting off the power supply and using insulators or wooden sticks to separate the wires, etc.); The second step is to check the vital signs of the person who was electrocuted and provide rescue according to the situation (including judgment of conscious breathing, calling for help, cardiopulmonary resuscitation when breathing unconsciously, etc.).

Electrician questions, simple answers. Key points of first aid methods for electric shock

1. Cut off the power supply immediately, or use non-conductive objects such as dry wooden sticks, bamboo sticks or dry cloth to remove the injured person from the power supply as soon as possible. First aiders must not directly contact the injured person due to electric shock to prevent themselves from being electrocuted and affecting the rescue work.

2. When the wounded person is disconnected from the power source, the general condition of the wounded person should be checked immediately, especially the breathing and heartbeat. If breathing and heartbeat are found to have stopped, rescue should be carried out immediately.

(1) Mild illness: that is, those who are conscious and can breathe and heartbeat independently. The injured person should lie down on the ground and be observed closely. Do not stand or move for the time being to prevent secondary shock or heart failure.

(2) For those who have stopped breathing and have a heartbeat, lie down on the spot, unbutton their clothes, unblock the airway, and perform mouth-to-mouth artificial respiration immediately. If possible, tracheal intubation and pressurized oxygen artificial respiration can be performed. You can also acupuncture points such as Renzhong, Shixuan, and Yongquan, or give respiratory stimulants (such as lobeline, caffeine, and colamin).

(3) If the heart has stopped and breathing is present, external chest cardiac compressions should be performed immediately.

(4) For those who have stopped breathing and heartbeat, external chest compressions should be performed while artificial respiration is performed to establish breathing and circulation and restore the oxygen supply to the organs throughout the body. For on-site rescue, it is best for two people to perform mouth-to-mouth artificial respiration and external chest heart compression respectively, in a ratio of 1:5, that is, one artificial respiration and five heart compressions. If there is only one person to be rescued at the scene, use a ratio of 15:2 for chest cardiac compressions and artificial respiration, that is, perform 15 external chest cardiac compressions first, and then perform 2 mouth-to-mouth artificial respirations. This is done alternately. The rescue must be carried out to the end. .

(5) When dealing with electric shock injuries, attention should be paid to whether there are other injuries. If the person is ejected from the power supply after being electrocuted or falls from a high altitude, it is often complicated by craniocerebral trauma, hemopneumothorax, visceral rupture, limb and pelvic fractures, etc. Any injuries or burns must be treated at the same time.

(6) During on-site rescue, do not move the injured casually. If movement is really necessary, the interruption time of rescue should not exceed 30 seconds. When moving the injured person or sending him to the hospital, in addition to making the injured person lie flat on a stretcher and padding his back with a flat hard board, resuscitation should be continued. For those who have stopped breathing, artificial respiration and chest compressions should be continued. Medical staff in the hospital should Treatment cannot be suspended before taking over.

What are the key points of first aid for electric shock?

If someone gets an electric shock, the power supply should be cut off immediately before rescuing. If the power supply cannot be found, use an insulating glue stick or wooden stick first. Remove electrical wires and other live objects that are in contact with the person receiving an electric shock to prevent electric shock during the rescue process. Immediately check the vital signs of the electrocuted person. If he is unconscious and breathing, you need to start cardiopulmonary resuscitation and call an ambulance. In short, for electric shock first aid, the most important thing is to handle the on-site environment safely, otherwise it will easily lead to further personal injury.

Steps of first aid for electric shock

1 In first aid for electric shock, the first step is to quickly remove the victim from the power source. The sooner, the better. Because the longer the current acts, the more serious the damage will be. 2 To disconnect from the power supply means to disconnect the switch, knife switch or other circuit-breaking device of the part of the live equipment that the person who got the electric shock came into contact with; or to try to separate the person who got the electric shock from the live equipment. When disconnecting from the power supply, rescuers must not only save people, but also protect themselves. 3. Before the electric shock victim is disconnected from the power source, rescuers are not allowed to touch the injured person directly with their hands because there is a risk of electric shock. 4. If the person who gets an electric shock is at a high place, he or she will fall from the high place after being disconnected from the power source. Therefore, precautions must be taken.

5. If an electric shock victim comes into contact with low-voltage live equipment, rescuers should try to quickly cut off the power supply, such as opening the power switch or knife switch, unplugging the power plug, etc.; or use insulated tools, dry wooden sticks, wooden boards, ropes, etc., or non-conductive objects to free themselves. If you get an electric shock, you can also grab the dry but not close-fitting clothes of the person who gets an electric shock and drag them away. Remember to avoid touching metal objects and the body of the person who gets an electric shock. You can also wear insulating gloves or dry your hands. Wrap insulated clothing and other materials to remove the person who received an electric shock; rescuers can also stand on an insulating mat or a dry wooden board to insulate themselves for rescue. To detach the person who gets electrocuted from the conductor, it is best to use one hand. If the electric current flows to the ground through the person who is electrocuted, and the person who is electrocuted is holding the wire tightly, you can try to stuff a dry wooden board under the body to isolate it from the ground. You can also use a dry wooden ax or pliers with insulated handles to cut the wire. Cut wires in phases, one by one, and stand on an insulating object or dry board if possible. 6. If an electric shock victim comes into contact with high-voltage live equipment, rescuers should quickly cut off the power supply or use insulating tools suitable for the voltage level (wear insulating gloves, insulating boots and use insulating rods) to extricate the electric shock victim. During the rescue process, rescuers should pay attention to maintaining a necessary safe distance between themselves and surrounding live parts. 7. If an electric shock occurs on an overhead pole, such as a low-voltage live line, if it is possible to cut off the power supply of the line immediately, the power supply should be cut off quickly, or the rescue personnel should quickly climb the pole, fasten their own safety belts, and use an insulating rubber handle to Wire cutters, dry non-conductive objects or insulating objects can be used to pull the person who gets an electric shock away from the power supply; if it is a high-voltage live line and it is impossible to quickly cut off the power switch, a method of hanging a metal short-circuit of appropriate length with sufficient cross-section can be used. The power switch has tripped. Before throwing, fix one end of the short-circuit line on the tower or grounding down conductor, and tie the other end to a heavy object. However, when throwing the short-circuit line, care should be taken to prevent arc injury or disconnection endangering personal safety. Regardless of the voltage level of the electric shock, rescuers should pay attention to preventing the possibility of falling from a height and the possibility of touching other live lines again when removing the electric shock victim from the power supply. 8. If the person who gets an electric shock touches a live high-voltage wire that is broken on the ground, and it has not been confirmed that the line is de-energized, the rescuers must not approach the person who gets the electric shock without taking safety measures (such as wearing insulating boots or temporarily jumping close to the person with both feet together). The disconnection point should be within the range of 8 to 10m to prevent the step voltage from hurting people. After the person who gets an electric shock breaks away from the live conductor, he should be quickly taken 8 to 10 meters away and then start first aid for electric shock immediately. Only after it is confirmed that the line is dead, first aid can be provided immediately after the person who has been electrocuted leaves the electric shock conductor. 9 When rescuing the injured from electric shock and cutting off the power supply, sometimes the lighting will lose power at the same time. Therefore, temporary lighting such as accident lighting and emergency lights should be considered. New lighting must meet the fire and explosion-proof requirements of the place of use. However, this should not delay the removal of the power supply and first aid. 1. If the injured person who is electrocuted is conscious, he should lie down on the spot, observe closely, and do not stand or move for the time being. 2 If the injured person who is electrocuted is unconscious, he should lie on his back on the spot and ensure that the airway is unobstructed. Call the injured person or tap his shoulder gently for 5 seconds to determine whether the injured person has lost consciousness. It is forbidden to shake the head of the injured person to call for the injured person. 3. The injured who need to be rescued should immediately carry out correct rescue on the spot and try to contact the medical department to take over the treatment. 4. Determination of breathing and heartbeat conditions: 4.1 If the injured person due to electric shock loses consciousness, the injured person’s breathing and heartbeat condition should be determined within 10 seconds by looking, listening, and testing. 4.1.1 Look - see if the chest and abdomen of the casualty rise and fall; 4.1.2 Listen - put your ear close to the mouth and nose of the casualty and listen for the sound of exhalation; 4.1.3 Test - test whether there is exhalation from the mouth and nose airflow. Then use two fingers to gently test whether the carotid artery in the depression next to the Adam's apple on one side (left or right) is pulsating. 4.2 If there is neither breathing nor carotid pulse according to the results of looking, listening and testing, it can be judged that the breathing and heartbeat have stopped. 1. When the electrocuted victim’s breathing and heartbeat stop, he should immediately follow the three basic measures of cardiopulmonary resuscitation to support life and conduct on-site rescue correctly.

a. Unobstructed airway; b. Mouth-to-mouth (nose) artificial...

~~What are the first aid measures if you are electrocuted?

Precautions for electric shock first aid and traditional first aid methods: 1 Precautions during on-site rescue 1.1 Re-judgment during the rescue process (1) When performing cardiopulmonary resuscitation to rescue an electric shock victim, pay attention to changes at any time. After pressing and blowing for 1 minute (equivalent to four 15:2 pressure and blowing cycles during a single-person rescue), use the method of watching, listening, and testing to complete a re-judgment within 5 to 7 seconds to determine whether the electrocuted person's breathing and heartbeat have recovered. (2) If it is determined that the carotid artery is pulsating but there is no breathing, pause the chest compressions and continue to blow air 4 times (1 to 1.5 seconds each time), and then blow every 4 to 5 seconds (that is, about 12 to 1.5 seconds). 16 times/min). If the pulse and breathing have not recovered, cardiopulmonary resuscitation should continue. (3) During the entire rescue process, re-judgment should be made every few minutes, and the determination time should not exceed 5 to 7 seconds. On-site rescue must not be abandoned before medical personnel take over the rescue. 1.2 Movement and transfer (1) Cardiopulmonary resuscitation should be carried out at the scene. Do not move the electrocuted person at will just for temporary convenience. If it is really necessary to move or send the patient to the hospital, the rescue interruption time should not exceed 30 seconds. The person who was electrocuted should be asked to lie flat on a stretcher with a flat hard board on his back. Do not stop until medical personnel take over the treatment. (2) If possible, use a plastic bag filled with crushed ice chips to make a hat-like wrap around the head of the person who was electrocuted, exposing the eyes, so as to lower the temperature of the brain and strive for early recovery of the heart, lungs and brain. 1.3 Treatment of the injured person after the electric shock improves (1) There may be another early arrest after the heartbeat and breathing recover, so the person must be closely monitored and ready to rescue again at any time. (2) After the initial recovery, the person who was electrocuted may become confused, trance-like, or emotionally agitated, and efforts should be made to keep him calm. 2 Other precautions for emergency rescue (1) During the first aid process, if it is found that the skin of the person who was electrocuted changes from purple to red, and the pupils change from large to small, it means that the effect has been seen; when the person who was electrocuted has slight opening and closing of his lips, movable eyelids, or there is something in his throat If you do this, you should observe whether breathing and heartbeat recover. Rescue can only be terminated unless the victim's breathing and heartbeat have returned to normal, or if there are obvious symptoms of death (pupil dilation without light response, red corpse spots on the back and limbs, gray skin and cold body) and the doctor diagnoses him as dead. . (2) For local trauma caused by electric injuries and falls, appropriate treatment should be carried out during on-site rescue to prevent bacterial infection and puncture of surrounding tissues due to falls and fractures, so as to reduce the pain of the electrocuted person and facilitate transfer to the hospital. 3. Other scientific methods for rescuing victims of electric shock. When rescuing victims of electric shock on site, if possible, the following scientific methods can be used to achieve the best possible results in the first aid work. (1) New acupuncture therapy: Motherland’s medicine is a great treasure house, especially acupuncture therapy is also very effective in first aid for electric shock. During the on-site rescue process, medical staff can cooperate with the use of new acupuncture therapy of traditional Chinese medicine. The acupuncture points used are: Renzhong, Baihui, Fengfu, Fengchi, Qiemen, Neiguan, Shenmen, Zhongchong, Shaoshang, Shixuan, Yongquan, etc. Specifically, appropriate acupuncture points can be selected according to the different conditions of the person receiving electric shock; a slightly thicker needle can also be used to perform acupuncture and bloodletting at Renzhong, Shixuan and other acupoints. (2) Forced oxygen delivery: While performing artificial respiration, an oxygen mask or oxygen bag can be used and a certain pressure is applied to force the person who receives an electric shock to inhale a mixture of oxygen and 7% carbon dioxide. This is very helpful in restoring the normal breathing and heartbeat functions of the person who receives an electric shock. benefit. (3) Injection of stimulants: According to the specific symptoms and development of the electrocuted person, doctors can inject an appropriate amount of respiratory center stimulants at the appropriate time in a hospital with adequate medical conditions to help the electrocuted person return to normal. 4. Can a person who gets an electric shock be given a cardiac shot? "Heart-stimulating shot" is a common name, and it is also called a "life-saving shot". There are many kinds of cardiac injection drugs, such as epinephrine hydrochloride, norepinephrine, isoproterenol, etc. According to modern medical literature and relevant experimental verification, the past view that injecting epinephrine and other drugs during emergency treatment will worsen ventricular fibrillation is not entirely correct.

On the contrary, depending on the specific situation of the person who received an electric shock, if the ventricular fibrillation is "fine fibrillation" rather than "coarse fibrillation" (the electrocardiogram waveform is a sawtooth wave), an appropriate amount of such drugs should be injected or accompanied by a "defibrillator" for electric defibrillation. It can reduce the frequency of heart fibrillation and increase the amplitude of contraction and contraction, thereby promoting the heart to return to normal beating. But...
