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

The appropriate compression to ventilation ratio for adult CPR is 30:2. This means that for every 30 chest compressions administered, 2 rescue breaths should be given. This ratio is designed to maximize the effectiveness of CPR by ensuring that adequate blood circulation is maintained through chest compressions while also providing sufficient oxygenation through ventilations.

In adults, high-quality chest compressions are a critical component of resuscitation efforts, and the 30:2 ratio is established based on research and guidelines that optimize survival rates in cardiac arrest situations. The focus on providing compressions at the rate of 100 to 120 per minute, followed by two rescue breaths, helps to balance the need for circulation and oxygenation.

This approach is different from the ratios used in pediatric patients or during two-rescuer scenarios, which may call for different compression to ventilation ratios, but for adult CPR, the 30:2 ratio has been found to be the most effective in real-world applications and aligns with current CPR guidelines.
