What is the recommended compression-to-breath ratio for adult CPR?

The recommended compression-to-breath ratio for adult CPR is 30 compressions to 2 breaths. This ratio is established to optimize the chances of survival during cardiac arrest by ensuring that sufficient blood circulation is maintained through chest compressions while also providing necessary oxygenation with rescue breaths.

In adult CPR situations, high-quality chest compressions are the priority, so the 30:2 ratio allows for a larger number of compressions to be delivered quickly, effectively maintaining circulation. This balance between compressions and breaths aims to support vital organ function while minimizing interruptions, thus enhancing the overall effectiveness of the resuscitation effort. This guideline is widely accepted and promoted by organizations such as the American Heart Association, reinforcing its importance in effective CPR practices.
