Why is it important to have the correct hand placement during CPR?

Having the correct hand placement during CPR is crucial because it directly affects the effectiveness of chest compressions, which are essential for maintaining blood circulation during a cardiac arrest. Proper hand positioning ensures that compressions are delivered at the correct location on the chest, typically on the lower half of the sternum, which maximizes the force applied to the heart. This facilitates the most efficient blood flow to vital organs, particularly the brain and heart, during the crucial moments when the heart is not beating effectively.

Additionally, correct hand placement ensures that the compressions are delivered at the necessary depth and rate, which guidelines recommend to be at least 2 inches deep and at a rate of 100 to 120 compressions per minute. When compressions are performed correctly, it increases the chances of survival and recovery for the victim, significantly improving the outcomes in life-threatening situations.
