Which landmark is used to locate proper hand position during cardiopulmonary resuscitation (CPR)?

The correct answer focuses on the xiphoid process, which serves as a critical anatomical landmark when determining where to position the hands for effective chest compressions during cardiopulmonary resuscitation (CPR). The xiphoid process is the small, cartilaginous extension of the sternum located at the base of the breastbone. Proper hand placement is crucial for achieving the correct compression depth and minimizing the risk of injury to the internal organs.

During CPR, rescuers place the heel of one hand on the lower half of the sternum, avoiding the area where the xiphoid process is located and providing compressions just above this landmark. This ensures that compressions are directed into the chest cavity where they can effectively circulate blood to vital organs.

Understanding the significance of landmarks like the xiphoid process in CPR is essential for anyone trained in emergency response. It emphasizes the importance of anatomical knowledge in performing life-saving techniques safely and effectively.
