What is the correct ratio of chest compressions to breaths in CPR for adults?

The correct ratio of chest compressions to breaths in CPR for adults is 30 compressions to 2 breaths. This guideline is established to optimize blood flow and ensure sufficient oxygenation during cardiopulmonary resuscitation.

The 30:2 ratio allows for a quick and efficient response when performing CPR, as the priority is to maintain circulation through continuous chest compressions. By performing 30 compressions first, you can help maintain blood flow to vital organs, particularly the heart and brain, before delivering breaths. This approach is crucial, especially since the compressions also create intrathoracic pressure, which aids in the movement of air into the lungs, making the subsequent rescue breaths more effective.

This method reflects the current recommendations from the American Heart Association, acknowledging that high-quality chest compressions are one of the most critical components of effective CPR.
