How deep should chest compressions be in adult CPR?

In adult CPR, chest compressions should be performed at a depth of at least 2 inches. This depth is crucial because it ensures adequate blood flow is generated during compressions, allowing for effective perfusion of vital organs, especially the heart and brain. Compressions that are too shallow may not produce sufficient blood circulation, which can significantly reduce the chances of survival for a patient in cardiac arrest. The recommended depth also helps to allow for full recoil of the chest between compressions, which is important for optimal blood return to the heart.

Guidelines from organizations such as the American Heart Association emphasize the importance of the proper depth of compressions to maximize the effectiveness of the CPR being administered. By adhering to the 2-inch depth guideline, first responders can provide the best possible care to patients in need of resuscitation.
