What is the standard compression-to-breath ratio during adult CPR?

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

Answer: (B)

During adult CPR, the standard compression-to-breath ratio is 30:2. This means that for every 30 chest compressions, two rescue breaths should be given. This ratio was established to ensure that patients receive effective circulation through compressions while also providing oxygenation through breaths. The focus on compressions is crucial because they maintain blood flow to vital organs during cardiac arrest. The 30:2 ratio balances the need for continuous compressions with the importance of delivering oxygen, which is essential during resuscitation. In contrast, other ratios such as 15:2, 10:1, or 20:2 do not align with current guidelines for adult CPR, which emphasize the improvement of outcomes through the 30:2 approach, especially in untrained bystanders who may find it simpler to remember and implement this ratio.
