What is the correct compression to breath ratio for two rescuer adult CPR?

• A. 15:2
• B. 30:2
• C. 30:1
• D. 20:2

Answer: (B)

In two-rescuer adult CPR, the correct compression to breath ratio is 30:2. This means that for every 30 chest compressions performed, the rescuers should deliver 2 rescue breaths. This ratio is designed to provide a balance between maintaining circulation through effective chest compressions and ensuring adequate oxygenation through rescue breaths. The 30:2 ratio is used to maximize the chances of survival in an adult cardiac arrest situation, ensuring that the heart is receiving enough blood flow while also addressing the need for oxygenation. This approach aligns with current resuscitation guidelines that emphasize high-quality compressions at an appropriate rate and depth, paired with timely rescue breaths. The other options suggest different ratios, which are not standardized for adult CPR in the two-rescuer scenario, resulting in either insufficient or excessive rescue breaths relative to the compressions being delivered. The 30:2 ratio has been established as the most effective method in this context.
