During adult CPR, how deep should chest compressions be performed?

During adult CPR, chest compressions should be performed at a depth of at least 2 inches. This depth is crucial because effective compressions help to create sufficient pressure within the chest cavity to circulate blood and deliver oxygen to vital organs during cardiac arrest.

Compressions that are too shallow may not adequately perfuse the heart and brain, which are critical during such emergencies. Not only must the depth be sufficient, but compressions should also be delivered at a rate of 100 to 120 compressions per minute to maximize blood flow.

Additionally, the guideline of at least 2 inches strikes a balance between effectiveness and safety. Compressions deeper than this may risk injury, especially in specific populations such as the elderly or those with underlying medical conditions affecting bone structure. Therefore, adhering to the 2-inch depth standard ensures that the compressions are impactful while still being mindful of patient safety.
