The basic operation steps of cardiopulmonary resuscitation (CPR) after electrocution include recognizing cardiac arrest, calling the emergency center, and performing basic CPR. 1. Identify cardiac arrest: Ensure the safety of the emergency scene, immediately cut off the main power supply or use insulating materials to separate the patient from the power supply, and then implement treatment. Cardiac arrest after electrocution is characterized by the patient’s loss of consciousness and the disappearance of aortic pulsation. Need to tap the patient’s shoulders, call, and then touch the carotid artery whether there is a pulse, when confirming the electrocution of cardiac arrest should be carried out urgently after CPR. 2. Call the emergency center: when you find the electrocuted person’s cardiac arrest, call the people around you to help you call 120 emergency without delaying CPR. This is because CPR alone will not save the electrocution victim’s life, and he or she will need to be transported to a hospital in order to achieve a better outcome. 3. Basic cardiopulmonary resuscitation (CPR): Place the patient on a hard surface or bed, perform chest compressions 30 times and artificial respiration 2 times alternately to perform CPR, and the chest compressions should reach more than 100 times per minute. The amplitude of each compression should be no less than 5 centimeters for adults and no less than one-third of the chest thickness for children. It should be maintained until the emergency vehicle arrives. It should be noted that CPR is best performed by professionals or trained personnel.
