What is the recommended adult compression to ventilation ratio in CPR?

The recommended adult compression to ventilation ratio in CPR is 30 compressions to 2 breaths. This ratio is established by organizations like the American Heart Association and reflects updated guidelines aimed at maximizing the effectiveness of cardiopulmonary resuscitation during cardiac arrest.

This ratio is specifically designed for adult victims when a trained rescuer is delivering breaths alongside chest compressions. The emphasis on providing 30 compressions followed by 2 breaths ensures that the heart receives a sufficient number of compressions to maintain blood circulation before oxygen is delivered through rescue breaths.

Moreover, the higher frequency of compressions helps to generate a better blood flow to vital organs, especially the heart and brain, during the critical first minutes after a person has collapsed. Using this ratio allows rescuers to provide high-quality CPR that adheres to best practices for patient outcomes.

In contrast, the other options do not align with current guidelines and could impair the effectiveness of the lifesaving efforts. Choices that suggest ratios like 15 to 2 or 10 to 2 compressions result in fewer compressions over the same time period, which can be less effective in maintaining circulation. Similarly, the ratio of 20 to 1 does not provide enough compressions to ensure adequate blood flow. Following
