Introduction
During electric shock, cardiac arrest is most commonly caused by ventricular fibrillation. When performing cardiopulmonary resuscitation (CPR), if two rescuers are present, the compression-to-ventilation ratio for children aged 8 years and older and adults is 30:2—i.e., 30 chest compressions delivered at a rate of 100–120 compressions per minute, followed by 2 rescue breaths, all completed within 15–18 seconds.
During electric shock, sudden cardiac arrest is most commonly caused by ventricular fibrillation (VF); in some cases, respiratory arrest occurs first, followed secondarily by cardiac arrest.
When performing cardiopulmonary resuscitation (CPR), if two rescuers are present, the compression-to-ventilation ratio for children aged 8 years and older and adults is 30:2—i.e., 30 chest compressions delivered at a rate of 100–120 per minute within 15–18 seconds, followed by 2 rescue breaths administered mouth-to-mouth.
For children under 8 years old (excluding newborns), the compression-to-ventilation ratio is 15:2. The compression rate remains 100–120 per minute, with 15 compressions completed within 7.5–9 seconds.
If only one rescuer is available, the compression-to-ventilation ratio is 30:2 for all patients—including adults, children, and infants aged under 1 year (excluding newborns). The 30 compressions must again be delivered within 15–18 seconds at a rate of 100–120 per minute.
