During CPR, what is the ratio of compressions to rescue breaths for adults?

The appropriate ratio of compressions to rescue breaths during CPR for adults is 30:2. This means that for every 30 chest compressions delivered, two rescue breaths should be given. This ratio is significant because it emphasizes the importance of maintaining a high frequency of compressions, which helps to circulate blood to vital organs during a cardiac arrest.

The 30:2 ratio also reflects the recommended practice for both untrained bystanders performing Hands-Only CPR and trained responders, ensuring consistency in CPR efforts. High-quality chest compressions are crucial for improving the chances of survival, as they help maintain blood flow to the heart and brain.

While other ratios may be applicable in different scenarios or for different age groups, such as for pediatric patients, the 30:2 ratio is the standard for adult victims and most closely aligns with current guidelines in providing effective CPR.
