Javier is performing CPR on his friend. What is the MOST appropriate hand positioning for Javier to use?

For adult CPR chest compressions, Javier should place the heel of one hand in the center of the chest on the lower half of the sternum, then place his other hand on top. This provides firm, controlled compressions. The forehead-and-chin position is used to open the airway, not to position the hands for chest compressions.
