Where should you place your hands for compressions during CPR?

The correct placement for hands during CPR compressions is at the center of the chest. Specifically, compressions should be performed on the lower half of the sternum, which is located in the middle of the chest between the nipples. This position allows for effective compressions to circulate blood to vital organs, particularly the brain and heart.

Placing hands just above the point where the rib cage joins is incorrect because this location does not provide adequate pressure on the heart to achieve sufficient blood flow. It's crucial to aim for the sternum as it facilitates a deeper compression with minimal risk of injury to the ribs. Additionally, the lower abdomen is not only far from the heart, but compressions in this area would not contribute to the chest's upward motion necessary for effective blood circulation. Placing hands near the shoulder would similarly not engage the heart effectively, leading to ineffective CPR.

In summary, the correct hand placement is vital for delivering the necessary compressions that can save a life, which reinforces why the center of the chest is the proper location during CPR.
