What is the recommended rate of chest compressions per minute during CPR?

The recommended rate of chest compressions per minute during CPR is 100 to 120 compressions. This rate is optimal for effectively circulating blood to vital organs during a cardiac arrest scenario. Compressions should be delivered at a depth of at least 2 inches and at a rate that allows for quality CPR, aiming for minimal interruptions.

While the option indicating 30 to 1 correctly reflects the compression-to-breath ratio used in CPR for adults when giving rescue breaths, it does not address the rate of compressions alone. The main goal during CPR is to maintain the highest possible rate of effective compressions, hence focusing on 100 to 120 compressions per minute. This range is supported by guidelines provided by organizations such as the American Heart Association, which emphasizes the importance of high-quality chest compressions in enhancing survival rates in cardiac arrest situations.
