What is the recommended compression depth for adult CPR?

The recommended compression depth for adult CPR is 2 inches. This depth is essential because it effectively allows for adequate blood flow to the heart and brain during resuscitation efforts. Compressions that are too shallow may fail to generate the necessary blood pressure needed to maintain circulation during cardiac arrest.

Research and guidelines from organizations such as the American Heart Association emphasize the importance of this 2-inch depth to ensure that compressions can reach the heart adequately, allowing for better chances of restoring a functional rhythm and improving survival rates. By ensuring the depth is maintained, rescuers can maximize the effectiveness of CPR, which is critical during emergencies.

It's important to also be aware that overly deep compressions, while not advisable, can cause injury to the chest or organs, reinforcing the significance of adhering to the recommended depth.
