In CPR, what should be the ratio of compressions to rescue breaths?

• A. 15:1
• B. 30:2
• C. 20:2
• D. 50:2

Answer: (B)

In CPR for adults, the recommended ratio of compressions to rescue breaths is 30:2. This means that for every 30 chest compressions performed, 2 rescue breaths should be administered. This ratio is established to ensure a balance between maintaining blood circulation through chest compressions and providing oxygen to the victim's lungs via rescue breaths. The 30:2 ratio is specifically advised for adult victims who require CPR when responding in a layperson scenario. This method ensures that compressions, which are critical for circulating blood to the brain and heart, are prioritized while still delivering necessary breaths to maintain oxygen levels. This CPR ratio is designed to enhance the chances of survival during cardiac arrest and is widely taught in CPR certification courses, aligning with guidelines from organizations such as the American Heart Association.
