What ratio of compressions to breaths is recommended during adult CPR?

The recommended ratio of compressions to breaths during adult CPR is 30:2. This guideline indicates that for every 30 chest compressions administered, rescuers should provide 2 rescue breaths. This ratio is crucial for effective CPR, as it maintains a higher rate of blood circulation through compressions while ensuring that the victim receives adequate oxygenation through the rescue breaths.

The 30:2 ratio enhances the chances of survival in an adult who has gone into cardiac arrest by providing a systematic approach that allows for continuous blood flow and oxygen delivery to vital organs, particularly the heart and brain. It's also easier to perform and remember during stressful situations, which is vital in an emergency.

Rescuers should ensure that compressions are done at a adequate depth and rate—aiming for a rate of about 100 to 120 compressions per minute—while minimizing interruptions in compressions to maximize blood flow. The consistency and rhythm of this ratio are what make it effective compared to other options that vary significantly in their approach to managing rescue breaths and compressions.
