Introduction
If two rescuers are present:
- For children aged 8 years and older or adults, the chest compression rate is 100–120 compressions per minute, followed by 2 rescue breaths (mouth-to-mouth).
- For children under 8 years (excluding newborns), the chest compression rate remains 100–120 compressions per minute, with 15 compressions completed within 7.5–9 seconds.
If only one rescuer is present, the compression-to-ventilation ratio is consistently 30:2 for all age groups (except newborns).
During electric shock, sudden cardiac arrest is most commonly caused by ventricular fibrillation; 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 within 15–18 seconds at a rate of 100–120 compressions per minute, 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—regardless of whether the patient is an adult, a child, or an infant aged under 1 year (excluding newborns)—the compression-to-ventilation ratio is uniformly 30:2; the 30 compressions must again be delivered within 15–18 seconds at a rate of 100–120 compressions per minute.
