What is the recommended compression to ventilation ratio for adults during CPR?

The recommended compression to ventilation ratio for adults during CPR is 30:2. This ratio is designed to ensure that a sufficient number of compressions—30 in this case—are delivered to maintain blood flow to vital organs, while still providing two rescue breaths to achieve adequate oxygenation.

This approach reflects the need for a high-quality chest compressions during cardiopulmonary resuscitation (CPR), as continuous compressions help to mechanically circulate blood, thereby increasing the chances of survival in cardiac arrest scenarios. The two rescue breaths following the compressions help restore oxygen levels in the person's bloodstream, which is vital since the heart is not effectively pumping blood that carries oxygen to tissues.

This specific ratio has been established based on research and guidelines that balance the importance of compressions and ventilations to optimize outcomes for victims of cardiac arrest. Following these guidelines can significantly improve the efficacy of the resuscitation efforts.
