What is the appropriate position of the rescuer’s hands during chest compressions?

The appropriate position of the rescuer’s hands during chest compressions is with one hand on top of the other and the heel of the hand positioned in the center of the chest. This technique is essential for delivering effective compressions during cardiopulmonary resuscitation (CPR).

When the hands are stacked in this manner, the rescuer can apply consistent and adequate pressure to the chest, which is critical for maintaining blood circulation to vital organs, especially the heart and brain. The heel of the hand being placed in the center ensures that the compressions are delivered at the correct location, which aligns with the lower half of the breastbone (sternum). This helps to maximize the effectiveness of the compressions, enabling the heart to pump blood more efficiently during cardiac arrest situations.

The correct hand position also promotes better body mechanics for the rescuer, reducing the risk of injury and allowing for sustained compressions at a depth of about 2 inches with the right rate of 100 to 120 compressions per minute. Proper technique ensures that the compressions are both effective and sustainable over the duration of CPR until emergency medical services arrive or the individual shows signs of recovery.
