For a single responder, what is the compression to ventilation ratio for both adults and children?

In the context of basic life support (BLS) for adults and children, the recommended compression to ventilation ratio for a single rescuer is 30 compressions followed by 2 breaths. This ratio is designed to maximize the efficiency of chest compressions while ensuring that the victim receives adequate ventilation.

The primary goal during a cardiac arrest is to maintain circulation to vital organs; thus, high-quality compressions are prioritized. After 30 compressions, delivering 2 ventilations helps to ensure that oxygen is getting into the lungs, which is crucial for survival. This ratio allows for a quick return to chest compressions, which is vital in maintaining blood circulation and promoting successful resuscitation outcomes.

Understanding this ratio is fundamental for anyone performing CPR, as it directly impacts the effectiveness of the intervention and the potential for positive outcomes in emergency situations.
