What is the appropriate hand position for chest compressions in adult CPR?

The appropriate hand position for chest compressions in adult CPR is placing the heel of one hand on the lower third of the sternum. This technique is critical because compressing at the correct location allows for optimal force to be applied to the heart, thus effectively circulating blood during cardiac arrest. The positioning of the hands ensures that compressions are delivered directly to the heart, as well as allowing for proper depth and rate of compressions, which should be at least 2 inches deep and at a rate of 100-120 compressions per minute.

Additionally, the placement of both hands on the lower third of the sternum helps to stabilize the compressions, maximizing the efficiency of each thrust. This technique minimizes the risk of injury to the ribcage and improves the likelihood of successful resuscitation by enhancing blood flow to vital organs. Understanding this hand positioning is crucial for effective CPR and significantly impacts patient outcomes.
