Which CPR ratio applies to infant and child CPR?

• A. 30 to 2
• B. 15 to 1
• C. 20 to 2
• D. 10 to 1

Answer: (B)

In CPR, the ratio shows how many chest compressions you give before delivering breaths, and it changes for infants and children based on how many rescuers are present. When you’re doing CPR alone on an infant or child, you typically perform 30 compressions and then give 2 breaths, cycling back to compressions after the breaths. If a second rescuer is present, the cycle shifts to 15 compressions followed by 2 breaths, with rescuers swapping roles to keep the rate up and reduce pauses.

So, for two rescuers on a child or infant, the standard rhythm is 15 compressions to 2 breaths. The other numbers listed don’t match the established pediatric CPR cycles: 30:2 is the single-rescuer rhythm used across ages, while the 15:1 option would imply 15 compressions for 1 breath, which isn’t a standard cycle in pediatric CPR.
