What is the recommended ratio of breaths to compressions during CPR?

The recommended ratio of breaths to compressions during CPR is 30:2, which means that for every 30 chest compressions given, 2 rescue breaths should follow. This ratio is designed to provide optimal blood flow and oxygenation to the patient during cardiac arrest.

The 30:2 ratio is particularly important for adult victims, as it ensures sufficient compressions to maintain circulation while also delivering oxygen to the lungs. Compressions help to pump blood to vital organs, while breaths are crucial for providing oxygen to the bloodstream. The emphasis on maintaining a high number of compressions within a short timeframe is based on research indicating that continuous and effective chest compressions significantly improve survival rates.

In contrast, other options suggest ratios that do not align with current guidelines, which are focused on maximizing the effectiveness of CPR efforts. Night and day distinctions exist between these ratios, as they can lead to either a lack of adequate blood flow or suboptimal delivery of oxygen if used incorrectly. Thus, adhering to the 30:2 ratio is essential for ensuring the best chance of survival for someone experiencing cardiac arrest.
