What is the appropriate compression to ventilation ratio for adult CPR performed by a single rescuer?

The correct compression to ventilation ratio for adult CPR performed by a single rescuer is 30:2. This means that for every 30 chest compressions given, 2 rescue breaths should be administered. This ratio is recommended to ensure that enough blood is circulated throughout the body while also providing oxygenation through ventilations.

The reasoning behind this specific ratio is based on research and guidelines established by organizations such as the American Heart Association, which aim to optimize the chances of survival and recovery for cardiac arrest victims. By focusing on high-quality compressions that maintain blood flow to vital organs, while also delivering rescue breaths at an effective rate, the single rescuer can provide the best possible support during a critical emergency situation.

The other ratios offered are less effective for adult situations and have been revised in contemporary guidelines. The focus on the 30:2 approach highlights the importance of maintaining a balance between compression for circulation and breaths for oxygenation, particularly in a scenario where the rescuer is alone and must manage both aspects efficiently.
