What is the CPR compression-to-breath ratio for adults?

The correct compression-to-breath ratio for adult CPR is 30 compressions to 2 rescue breaths. This approach is recommended by the American Heart Association and is based on extensive research to optimize survival rates following cardiac arrest. The 30:2 ratio provides an effective balance between ensuring adequate blood circulation through compressions and offering sufficient ventilation through rescue breaths.

In adult CPR, the focus during the initial response is on high-quality chest compressions, which are critical for maintaining blood flow to the vital organs. Following every 30 compressions, the two rescue breaths are administered quickly to ensure the patient receives the necessary oxygen. This method maximizes the chances of maintaining both circulation and oxygenation until advanced medical help arrives.

Therefore, understanding the significance of this ratio helps individuals perform CPR more effectively and save lives in emergency situations.
