What is the ideal ratio of chest compressions to rescue breaths in CPR?

The ideal ratio of chest compressions to rescue breaths in CPR is 30 to 2. This means that for every 30 chest compressions given, you should provide 2 rescue breaths. This ratio is based on the understanding that high-quality chest compressions are critical for maintaining circulation during an emergency. The emphasis on compressions is essential because they help to keep blood flow to vital organs, especially the heart and brain, during cardiac arrest.

The 30:2 ratio also allows for a balance between compressions and breaths, ensuring that the victim receives adequate oxygenation without diminishing the effectiveness of the compressions. By following this guideline, you maximize the chances of restoring a heartbeat and improving the chances of survival for the victim until professional medical help arrives.
