What is the standard chest compression to ventilation ratio for adult single-rescuer CPR?

Explanation:
During adult single-rescuer CPR, you deliver 30 chest compressions followed by 2 rescue breaths in a cycle. This 30:2 pattern is chosen to maximize blood flow to the heart and brain while providing enough oxygen via breaths, with minimal interruptions to chest compressions. Keep the compressions at about 100–120 per minute and about 2 inches (5 cm) deep. The other ratios fit different scenarios—35:2? No; 15:2 is typically for two rescuers or pediatric cases, whereas options like 5:1 or 100:1 aren’t standard CPR patterns.
