What is the recommended compression-to-breath ratio for adult CPR?

The recommended compression-to-breath ratio for adult CPR is 30 compressions to 2 breaths. This approach is based on current guidelines that emphasize the importance of high-quality chest compressions to circulate blood effectively during cardiac arrest. The ratio focuses on maximizing the number of compressions within the critical timeframe when the heart is not pumping effectively, while providing breaths to ensure oxygenation.

This ratio is used in both the single-rescuer and two-rescuer CPR scenarios, making it a consistent and easy-to-remember guideline for first responders. The frequency allows for continuous compressions without excessive interruptions for breaths, as each compression contributes to blood flow, which is critical for maintaining organ function until professional medical help arrives.

Other ratios provided do not align with the established guidelines, which prioritize the 30:2 ratio as the standard practice in adult resuscitation efforts. Maintaining this standard ensures that responders can provide effective and efficient CPR, improving the chances of survival for the patient.
