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

The recommended compression to breath ratio for adult CPR is 30:2. This means that for every 30 chest compressions given, 2 rescue breaths should be provided. This ratio is based on guidelines from organizations such as the American Heart Association and is designed to maximize blood flow and oxygen delivery to vital organs during cardiac arrest.

Using a 30:2 ratio allows rescuers to maintain a consistent rhythm of compressions, which is crucial for effective blood circulation. It ensures that compressions are prioritized, as they are the most critical component of CPR, assisting in maintaining blood flow to the heart and brain. The breaths are incorporated to provide oxygen; however, the emphasis on this ratio underscores the importance of chest compressions in the overall effectiveness of the resuscitation process.

Other options, like 15:2 or different ratios, do not align with current CPR guidelines for adults and may not provide the same level of efficacy in terms of maintaining circulation during an emergency situation.
