During CPR, how should the technician position their hands for effective compressions?

The correct positioning of the hands during CPR is essential for delivering effective chest compressions, which are crucial for maintaining blood circulation in a person experiencing cardiac arrest. Placing the interlocked hands on the lower half of the sternum allows the individual delivering compressions to apply the necessary force efficiently and in the correct location.

Positioning the hands in this manner ensures that compressions are directed to the center of the chest, where they can effectively compress the heart between the sternum and the spine. This maximizes blood flow to vital organs and increases the chances of successful resuscitation. The hands should be positioned at least two inches deep for adults to achieve adequate circulation.

In contrast, placing a hand on the patient’s forehead does not contribute to compressions and might even create a barrier to effective chest compression. Hands on the abdomen would not target the heart and instead distract from the compressions needed to restore circulation. Having one hand under the back could hinder effective compressions by reducing the ability to compress the heart fully. Therefore, using interlocked hands on the lower half of the sternum is the most effective technique for performing CPR.
