For child CPR with two rescuers, what ratio should be used?

• A. 15:2
• B. 30:2
• C. 20:2
• D. 10:2

Answer: (A)

The main idea is that when two rescuers are present for pediatric CPR, the emphasis includes more ventilation relative to chest compressions, so the recommended rhythm is 15 compressions followed by 2 breaths. Two rescuers can coordinate to deliver 15 rapid chest compressions with minimal interruption, then pause briefly to give 2 breaths, and resume. This helps maintain oxygenation in children, who are more likely to experience respiratory arrest as the cause of cardiac arrest.

Why this fits best: children benefit from more frequent breaths to support gas exchange while still keeping a steady pace of chest compressions. With one rescuer, the balance shifts toward fewer breaths per cycle to reduce interruptions, hence a 30:2 ratio. The other options don’t align with pediatric guidance and would either under-ventilate or disrupt the flow of compressions.

In practice, one rescuer handles compressions and the other provides breaths, then they switch as needed to prevent fatigue and keep the cycle smooth, aiming for a rate of about 100–120 compressions per minute with brief, purposeful breaths.
