What is the correct hand position for delivering chest compressions on an adult?

The correct hand position for delivering chest compressions on an adult is centered on the lower half of the breastbone, specifically in the middle of the chest. This position is crucial because it allows for effective compressions aimed at pumping blood to vital organs during a cardiac emergency. Placing the hands in the right location ensures that compressions leverage the strength of the chest wall while minimizing the risk of causing injury to the ribs or internal organs.

Compressing the chest at this location also aligns with guidelines that recommend a compression depth of at least two inches in adults, allowing for adequate cardiovascular support. Proper technique, including the positioning of the hands, is essential for maximizing the effectiveness of CPR and increasing the chances of survival for individuals experiencing cardiac arrest.
