What is the correct hand position for chest compressions on an adult?

The correct hand position for chest compressions on an adult is two hands interlocked on the center of the chest. This method ensures that the rescuer can apply sufficient force for effective compressions, which are critical in maintaining blood circulation during a cardiac arrest situation. Placing both hands provides a stronger and more stable surface for compressing the sternum, allowing for the necessary depth and rhythm of compressions, which should ideally be at least 2 inches deep at a rate of 100 to 120 compressions per minute.

This technique maximizes the efficiency of each compression, helping to generate adequate internal pressure to maintain blood flow to vital organs. Ensuring the hands are positioned correctly also helps reduce the risk of injury to the rescuer and improves the chances of a successful resuscitation. Other positions, such as using only one hand or placing hands inappropriately, do not deliver the required force and could compromise the effectiveness of the CPR being administered.
