During two-rescuer infant CPR, what ratio should be used when the second rescuer returns?

• A. 30:2
• B. 20:2
• C. 15:2
• D. 5:2

Answer: (C)

In two-rescuer infant CPR, the pattern used is 15 compressions followed by 2 rescue breaths. Having a second rescuer present lets you split tasks: one person keeps the chest compressions steady while the other provides breaths, so you can deliver effective ventilation without pausing compressions too long. This 15:2 cycle helps maintain blood flow while improving oxygen delivery, and rescuers typically switch roles every 2 minutes or after completing the cycle to prevent fatigue from reducing quality. The other ratios aren’t used in this two-rescuer infant scenario—30:2 is for a single rescuer, and the 20:2 or 5:2 patterns aren’t standard.
