How many rescue breaths should be given after every 30 compressions?

The correct answer is that you should give 2 rescue breaths after every set of 30 compressions. This guideline is based on CPR protocols established for adult victims and ensures that sufficient air is provided to the lungs, facilitating gas exchange and improving the chances of resuscitation.

In a typical adult CPR scenario, the compression-to-breath ratio of 30:2 is recommended by organizations such as the American Heart Association. This means that after delivering 30 chest compressions to maintain blood flow, rescuers pause briefly to give 2 rescue breaths. The breaths should be delivered slowly and properly to ensure that the chest rises, indicating effective ventilation.

This ratio is crucial because it balances the need for continuous blood circulation through chest compressions with the need to restore oxygen levels through rescue breaths. Giving only 1 or more than 2 breaths could disrupt the rhythm and efficiency of CPR, making this two-breath guideline effective and widely adopted in training programs.
