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 crucial because it maximizes the effectiveness of the chest compressions, which are the most vital aspect of CPR for maintaining blood flow. The emphasis on 30 compressions followed by 2 breaths helps to ensure that the victim receives sufficient blood circulation through consistent and effective compressions before a rescue breath is provided. This method enhances the chances of survival, especially in cases of cardiac arrest where timely and quality compressions are essential. Following this specific ratio assists in maintaining a rhythm that is easier to perform and remember during a high-stress situation.
