Where should your bottom hand be placed on a person's chest during compressions?

The correct placement of the bottom hand on a person's chest during chest compressions is indeed on the lower half of the sternum. This positioning is essential for effective compressions during cardiopulmonary resuscitation (CPR). The heart is located directly behind the sternum, and compressing in the lower half helps to create sufficient pressure on the heart to circulate blood to vital organs.

Placing the hand in this position allows for optimal force application and minimizes the risk of causing harm to the ribs or other structures during compressions. It also helps to ensure that the compressions are performed at the correct depth, contributing to increased chances of resuscitation success. Proper hand positioning is a fundamental technique that enhances the efficacy of CPR, and effective compressions are critical in providing artificial circulation until advanced medical services can take over.
