What is the correct algorithm for chest compressions to rescue breaths during basic life support?

The correct algorithm for chest compressions to rescue breaths during basic life support is a 30:2 ratio. This means that for every 30 chest compressions delivered, 2 rescue breaths should be administered. This ratio is widely accepted in guidelines for adult CPR because it balances the need for maintaining blood circulation through compressions while also providing oxygen to the lungs through rescue breaths. The focus on delivering a sufficient number of compressions ensures that the heart has adequate output to support vital organs, while the breaths help to sustain oxygenation, which is critical for survival until professional help arrives.

Other ratios, such as 30:15, 5:1, and 15:1, are not recommended for adult CPR, as they can compromise the effectiveness of the compressions. It is crucial to maintain the 30:2 ratio for optimal performance in a resuscitation scenario.
