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

The compression-to-breath ratio for adult CPR is 30:2, which means that for every 30 chest compressions delivered, 2 rescue breaths should be given. This ratio is recommended in the 2020 Guidelines for CPR and Emergency Cardiovascular Care by the American Heart Association.

This approach prioritizes high-quality chest compressions, which are essential for maintaining blood circulation and ensuring that oxygenated blood reaches vital organs during cardiac arrest. The emphasis on higher compression counts in relation to breaths also aligns with the findings that demonstrate improved outcomes when compressions are adequately frequent and forceful, thereby creating effective circulation.

Utilizing the 30:2 ratio during adult CPR helps responders maintain a rhythm and manage both airway and circulatory needs to maximize the chances of survival until emergency services arrive. Understanding this ratio is critical for effective CPR practice and contributes to the overall effectiveness of the resuscitation efforts.
