How should you position your hands when delivering chest compressions?

When delivering chest compressions, the proper technique involves placing the heel of one hand on the center of the chest, specifically on the lower half of the breastbone (sternum), with the other hand resting on top of the first hand. This positioning ensures that you can generate enough force to effectively compress the heart between the sternum and the spine, helping to circulate blood during cardiopulmonary resuscitation (CPR).

Utilizing this technique allows for the desired depth and rate of compressions, which is crucial in maximizing blood flow to vital organs, especially the brain and heart, during a cardiac emergency. The alignment of the hands promotes stability and efficiency in delivering compressions, reducing the risk of injury to both the rescuer and the victim and making it easier to maintain the required rhythm—in general, at least 100 to 120 compressions per minute.
