If manual blowing is necessary to establish artificial respiration after an electrocution, the patient’s breathing is usually very weak or has stopped. The general frequency of blowing in this case is about 12-16 times per minute, every 4-5 seconds. If breathing and heartbeat stop at the same time, in the absence of a well established artificial airway, the general number of chest compressions and artificial respiration is 30:2, perform 30 chest compressions and perform two artificial respirations, two artificial respirations should be completed within 10 seconds, usually once every 4-5 seconds. If the artificial airway is established, commonly tracheal intubation, can be sustained chest compressions while being able to continuous artificial respiration, the frequency of artificial blowing is about 12-16 times per minute.
