What is the compression depth for adult CPR?

The recommended compression depth for adult CPR is 2 inches. This depth is important because it allows for effective chest compressions, ensuring that enough pressure is applied to circulate blood throughout the body. Compressions that are too shallow may not adequately perfuse vital organs, particularly the heart and brain, which can lead to further complications or decreased chances of survival.

The recommendation comes from guidelines established by organizations such as the American Heart Association, which emphasize that compressions should be both deep and at a rate of 100 to 120 compressions per minute. Achieving the correct depth is crucial for creating sufficient blood flow, thereby increasing the likelihood of reviving a patient in cardiac arrest. Maintaining this depth also aids in minimizing fatigue for the rescuer, allowing for more effective management of the situation until advanced medical help arrives.
