During CPR, what is the position of the rescuer’s hands when delivering chest compressions?

The correct positioning of the rescuer’s hands during chest compressions is on the lower half of the breastbone, also known as the sternum. This location is crucial for delivering effective compressions, which are essential for maintaining blood flow during cardiac arrest.

When compressions are applied to the lower half of the breastbone, it allows for the heart to be compressed adequately, facilitating the return of blood to the vital organs. Proper hand placement ensures that the compressions can generate enough pressure to maintain circulation. Additionally, this position minimizes the risk of injury to the ribs and helps achieve the recommended depth and rate of compressions, which are vital for successful resuscitation efforts in adult patients.

The other options either position the hands too high, as in near the collarbone, or too low, below the xiphoid process or near the diaphragm, which can lead to ineffective compressions and increase the likelihood of causing injury to internal organs. Proper technique is critical in CPR to maximize the chances of survival and recovery.
