What is the recommended compression depth for adult CPR?

The recommended compression depth for adult CPR is at least 5 cm (2 inches). This depth is crucial for effectively compressing the chest during cardiopulmonary resuscitation. A depth of 5 cm ensures that enough pressure is applied to the heart, which can help generate adequate blood flow to the vital organs, particularly the brain and heart itself, during the critical moments of cardiac arrest.

Compressing to this depth also aligns with guidelines established by major resuscitation organizations, which emphasize the importance of achieving a balance between adequate depth and rate of compressions to maximize the chances of survival. Compressing too shallowly may not create sufficient blood flow, whereas compressing deeper than recommended can increase the risk of injury to the patient's chest and organs. Adhering to the 5 cm depth allows for the most effective and safe delivery of CPR.
