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, rescuers should deliver 2 rescue breaths. This ratio is based on guidelines that emphasize high-quality chest compressions as the most critical component in maintaining blood flow to vital organs and increasing the chances of survival in a cardiac arrest situation.

The rationale for this specific ratio is that it allows for a high number of compressions to be delivered, which ensures adequate circulation while still providing the necessary ventilations to support oxygenation. Delivering compressions at this ratio helps maintain an effective CPR rhythm and maximizes the benefits of both compressions and breaths. This approach helps prevent interruptions in chest compressions, which can significantly reduce the effectiveness of CPR.

Adhering to the 30:2 ratio has been shown to improve outcomes in cardiac arrest scenarios, making it a fundamental protocol for healthcare providers and rescuers alike.
