In two-rescuer CPR, what is the compressions-to-breaths ratio?

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

Answer: (B)

In two-rescuer CPR, the rhythm is organized so that one rescuer maintains chest compressions while the other provides breaths, creating a cycle of 15 compressions followed by 2 breaths. After delivering the breaths, compressions resume immediately and the cycle continues. This setup minimizes interruptions to circulation while ensuring a quick, effective ventilation, which is why the 15:2 ratio is used when two rescuers are present. If only one rescuer is available, the ratio changes to 30:2 to balance the need for ventilation with the greater burden of performing both tasks alone.
