What is the correct compression to ventilation ratio for adult CPR?

The correct compression to ventilation ratio for adult CPR is 30:2. This ratio indicates that for every 30 chest compressions, two rescue breaths should be delivered. This guideline is part of the fundamental approach to resuscitation and aims to maximize the effectiveness of both compressions and ventilations.

The reasoning behind this ratio is based on current CPR guidelines which emphasize the importance of maintaining adequate blood circulation and oxygenation during a cardiac arrest situation. Chest compressions are critical for creating blood flow to vital organs, particularly the brain and heart. The 30:2 ratio allows for a balance between the mechanical aid provided by compressions and the oxygenation offered by ventilations.

In contrast, other ratios such as 15:2 or 10:2 are not recommended for adults as they may not provide the same level of circulatory support while also ensuring that the individual receives necessary breaths within the optimal time frame. The 30:2 ratio has been established as the most effective in the context of adult CPR, contributing to improved survival rates and outcomes in cardiac arrest scenarios.
