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

The adult compression-to-ventilation ratio for CPR is indeed 30:2. This ratio means that for every 30 chest compressions administered, there should be 2 breaths given. This guideline is established to ensure that the victim receives adequate blood flow and oxygenation during cardiac arrest situations.

The reason this specific ratio is important is that it balances the need for effective circulation of blood through chest compressions with the critical need for oxygen delivery to the lungs. Providing compressions at the correct rates helps maintain perfusion to vital organs, while the ventilations allow for the exchange of oxygen and carbon dioxide.

The chosen ratio of 30 to 2 is supported by guidelines from major health organizations and is designed to maximize the efficacy of CPR in adults. This clear structure helps rescuers remember how to perform CPR effectively in emergencies.
