During a CPR response, what is the compression-to-breath ratio for adults?

The compression-to-breath ratio for adults during a CPR response is set at 30:2. This means that for every 30 chest compressions performed, the rescuer should deliver 2 rescue breaths. This ratio is designed to maximize blood flow to vital organs while providing adequate breaths to maintain oxygenation. The emphasis on a higher number of compressions compared to breaths reflects the importance of maintaining circulation during cardiac arrest, as compressions are critical for keeping blood flowing to the brain and heart.

This guideline stems from studies indicating that a higher frequency of compressions improves survival rates and outcomes for individuals experiencing cardiac arrest. Maintaining a consistent and effective ratio not only supports the physiological needs of the patient but also provides a standardized approach that can be utilized effectively in emergency situations.
