Where should hands be located for CPR on an adult?

The correct placement of hands for performing CPR on an adult is on the lower half of the breastbone, also known as the sternum. This location is critical because it allows for effective compression of the heart. When hands are positioned here, the rescuers can apply adequate force directly onto the heart, which is located behind the sternum and acts as a pump to circulate blood throughout the body.

Compressing lower on the breastbone helps ensure that the compressions are delivered at the correct depth and with the proper alignment to maximize blood flow to vital organs, especially the brain and heart. This placement also minimizes the risk of injury to other structures, as positioning the hands incorrectly can lead to ineffective compressions or potential harm.

The focus on the lower half of the breastbone emphasizes a proper technique that is vital for successful resuscitation efforts. However, other locations, such as the upper chest area or the abdomen, are not ideal for effective CPR, as they do not provide the direct access necessary to compress the heart effectively.
