What is the recommended compression to ventilation ratio for adult CPR?

The recommended compression to ventilation ratio for adult CPR is 30:2, which is a best practice established by leading organizations such as the American Heart Association. This ratio signifies that for every 30 chest compressions, there should be 2 rescue breaths.

This approach is designed to optimize the efficiency of CPR by ensuring that the victim receives a high rate of chest compressions, which are vital for maintaining blood flow to the brain and organs during cardiac arrest. The focus on a higher number of chest compressions helps to support circulation while still providing necessary ventilations to deliver oxygen.

In adult CPR, the emphasis has shifted toward compressions, as they are the most critical element in increasing the chances of survival. The 30:2 ratio allows for a swift delivery of compressions while providing critical ventilations that can support oxygenation. This method has been validated through research and is a core part of current CPR training standards.
