What is the correct hand placement for adult chest compressions?

The correct hand placement for adult chest compressions is on the lower half of the sternum. This positioning is essential for effective compressions, as it allows for optimal depth and force that can help circulate blood to vital organs during cardiac arrest. When the hands are placed too high on the sternum, it may limit the compressions' effectiveness by not allowing sufficient compression depth needed to adequately pump blood.

In cardiopulmonary resuscitation (CPR), the primary goal is to provide effective chest compressions that mimic the heart's pumping action. Placing the hands on the lower half of the sternum ensures that the compressions are delivered to the heart's area, helping to circulate blood properly. It is also important to keep the elbows straight and use your body weight to deliver the compressions, further enhancing their effectiveness.

Using incorrect placements, such as on the abdomen or collarbone, does not support the necessary mechanics of compressions and can lead to ineffective CPR that fails to deliver proper blood flow to the brain and other organs, which is critical during a cardiac emergency.
