Where should the hands be positioned for effective chest compressions during CPR?

For effective chest compressions during CPR, the hands should be positioned in the center of the patient's chest on the lower half of the sternum. This specific location allows for the most effective compression of the heart, which is located directly behind the sternum. By placing the hands here, the compressions can create the necessary pressure to help circulate blood, thereby delivering oxygen to vital organs until normal heart function can be restored or advanced medical help arrives.

Proper hand placement is crucial because it maximizes the effectiveness of each compression. If the hands are positioned too high or too low, it may not adequately compress the heart, which can lead to ineffective attempts at resuscitation. Additionally, compressing over the abdomen or collarbone can lead to injury or ineffective compressions, while positioning hands on the shoulders does nothing to aid circulation. Therefore, knowing and executing the correct hand placement during CPR is vital for any health care provider.
