Where do you place your hand when doing chest compression?

When performing chest compressions, place the heel of one hand on the center of the person's chest, specifically on the lower half of the sternum (breastbone). Then, interlock your other hand on top of the first hand and keep your arms straight. Ensure your shoulders are directly above your hands for effective compressions. Compress the chest at a depth of about 2 inches and at a rate of 100 to 120 compressions per minute.
