In pediatric CPR, what is the correct single-rescuer compression-to-breath ratio?

• A. 15:2
• B. 20:2
• C. 30:2
• D. 25:2

Answer: (C)

In a single rescuer pediatric CPR scenario, the recommended rhythm is 30 compressions followed by 2 breaths. This balance ensures the heart and brain receive adequate perfusion while still providing essential ventilation, and it fits with the guideline of delivering chest compressions at about 100–120 per minute with breaths each about 1 second long to achieve visible chest rise. If a second rescuer is present, the routine changes to 15 compressions followed by 2 breaths, which allows more frequent ventilation between sets. If an advanced airway is already in place, compressions are continuous and breaths are given every 6 seconds (about 10 breaths per minute) rather than using a fixed 30:2 pattern. The other ratios don’t align with the single-rescuer pediatric CPR standard.
