1. Immediately cut off the power supply, or use non-conductive objects such as a dry stick, bamboo rod, or cloth to help the injured person get away from the power source as soon as possible. First responders must not come into direct contact with the person who has been electrocuted, in order to avoid getting electrocuted themselves and thus preventing the rescue efforts from progressing. 2. Once the injured person is separated from the power source, their overall condition should be checked immediately, with particular attention paid to breathing and heartbeat. If breathing and heartbeat cease, first aid measures should be taken right there on the spot. (1) Mild cases: Those who are conscious with normal breathing and heartbeat should lie flat on the spot, under close observation; they should not stand or walk for now to prevent secondary shock or heart failure. (2) In cases of respiratory arrest with a functioning heartbeat, lay the patient down flat, loosen their clothing to keep the airway unobstructed, and immediately perform mouth-to-mouth resuscitation. If possible, intubate the trachea and provide oxygen therapy through forced ventilation. Acupuncture at points such as Renzhong, Shixuan, and Yongquan can also be used, or respiratory stimulants (such as amylanthine, caffeine, and coramine) can be administered. (3) In cases of cardiac arrest with breathing present, chest compressions should be performed immediately. (4) In cases where both breathing and heartbeat have stopped, external chest compressions should be performed simultaneously with artificial respiration in order to establish breathing and circulation and restore oxygen supply to the organs throughout the body. For on-site resuscitation, it is best for two people to perform mouth-to-mouth respiration and chest compressions separately, in a 1:5 ratio – that is, 1 breath per 5 compressions. If only one person is available for first aid at the scene, perform chest compressions and artificial respiration in a 15:2 ratio; that is, give 15 chest compressions followed by 2 breaths via mouth-to-mouth resuscitation, repeating this cycle. The efforts to save the life must be continued until the end. (5) When treating electric shock injuries, attention should be paid to the presence of any other injuries. In cases such as being thrown away from the power source after an electric shock or falling from a great height, complications such as cranial trauma, hemothorax and pneumothorax, organ rupture, and fractures of the limbs and pelvis often occur. Any injuries or burns must be treated simultaneously. (6) During on-site first aid, do not move the injured person arbitrarily; if movement is necessary, the interruption in first aid should not exceed 30 seconds. When moving a wounded person or transporting them to the hospital, in addition to laying the victim flat on a stretcher with a flat, hard board under their back, first aid efforts should continue; for those whose heartbeat and breathing have stopped, artificial respiration and chest compressions must be continued, and treatment must not be halted until medical staff at the hospital take over.

Use insulating material to separate the person who has been electrocuted from the power source, or turn off the main power supply; report to the supervisor and carry out rescue efforts

1. First, turn off the power supply. 2. Remove the person who has been electrocuted. 3. Provide immediate first aid and perform artificial respiration

1. Use insulating material to separate the person who has been electrocuted from the power source, or turn off the main power supply. 2. Assess for unconsciousness: loss of consciousness; check for no pulse in the carotid arteries; observe for no movement in the chest; feel for no breathing – call for help from others and dial 120； 3. Turn the patient’s head to the side to check for any foreign objects that may be blocking the airway, including phlegm; if present, remove them using a cotton swab ； 4. Artificial respiration: Open the airway, line it with gauze, and blow in air ； (If successful, the green light on the mannequin will flash; if the airway is not properly opened, air will be blown into the stomach and the red light will flash.) 5. Chest compressions: At the midpoint between the two nipples, apply pressure using the hypothenar area of one hand, with a depth of 4–5 cm and a frequency of 100 compressions per minute, at a ratio of 2:30 to artificial respiration ； (The 2000 International Guidelines for Cardiopulmonary Resuscitation specify a ratio of 2:15, to be repeated for 4 cycles; this is the latest standard. Similarly, a green light will flash each time a compression is performed correctly.) 6. One cycle consists of 2 breaths via artificial respiration plus 30 compressions; after completing 5 such cycles, it is then determined whether the patient’s breathing has resumed ； 7. Effect evaluation (criteria for effectiveness): Ability to feel the carotid pulse, systolic blood pressure above 60 mmHg, reduction in dilated pupils, improvement in cyanosis of the lips and nail beds, and restoration of spontaneous breathing

Quickly disconnect the electrocuted person from the power source and immediately turn off the switch to cut off the electricity. If it is necessary to rescue the person by hand in the absence of the above conditions, the rescuer must stand on a dry wooden board and pull the electrocuted person’s clothes to remove them from the power source. If the general condition is good, the patient should be observed in bed for 12-24 hours. For those with stopped breathing and heartbeat, artificial respiration and chest compressions should be performed immediately; the wound from the electric shock should be bandaged up and the person taken to the hospital for further treatment

First, turn off the power; only after confirming that it is off should you attempt to rescue the person
