During CPR, how many chest compressions should be performed before giving rescue breaths?

The recommended practice for adult CPR focuses on a rhythm of 30 chest compressions followed by 2 rescue breaths. This sequence is established to maintain effective blood circulation while providing artificial ventilation. The 30 compressions help to establish adequate blood flow to vital organs, while the subsequent rescue breaths ensure that oxygen is delivered to the lungs.

By adhering to this compression-to-breath ratio, you maximize the chances of restoring a normal heart rhythm and maintaining oxygenation of the brain and other vital organs. This protocol has been reinforced through guidelines set forth by organizations such as the American Heart Association, ensuring that responders provide efficient and effective CPR in emergency situations.
