Two rescuers in children or infants should use which compression-to-breath ratio during CPR?

• A. Three rescuers should alternate compressions every two minutes.
• B. Two rescuers in children/infants should use a 15:2 compression-to-breath ratio.
• C. One rescuer should perform continuous compressions with no breaths.
• D. Always perform compression-only CPR.

Answer: (B)

In pediatric CPR with two rescuers, the balance between chest compressions and rescue breaths is chosen to address the fact that many pediatric arrests are driven by hypoxia. By using a cycle that includes a substantial number of compressions followed by a small number of breaths, you maintain circulation while re-oxygenating the blood. With two rescuers, one can keep chest compressions going while the other delivers breaths, then switch roles after the cycle so perfusion isn’t interrupted for long. This approach optimizes both oxygen delivery and blood flow, which is especially important in children and infants. The other options don’t fit because they either describe a setup not standard for two rescuers, remove breaths altogether, or rely on compression-only CPR, which is not the preferred method for pediatric victims.
