What is the correct hand placement when performing chest compressions on an adult?

When performing chest compressions on an adult, the correct hand placement is as follows:

1. Locate the Sternum: Find the center of the person's chest. This is typically at the lower half of the sternum, which is the flat bone in the middle of the chest.

2. Hand Position: Place the heel of one hand on the center of the chest, on the lower half of the sternum.

3. Interlock Fingers: Place the heel of your other hand on top of the first hand. Interlock your fingers to ensure stability.

4. Keep Fingers Off the Chest: Make sure your fingers are lifted and not resting on the chest to avoid applying pressure to the ribs.

5. Body Position: Position your shoulders directly over your hands and keep your arms straight to use your body weight for effective compressions.

This hand placement ensures effective chest compressions, which are crucial for maintaining blood circulation during CPR.
