What should be the compression depth for adult CPR?

The recommended compression depth for adult CPR is at least 2 inches. This depth is crucial as it allows for the effective compression of the chest, which is necessary to create sufficient pressure in the heart to circulate blood to vital organs during cardiac arrest. Compressions that are deep enough ensure that the heart can adequately pump blood, improving the chances of survival until advanced medical help arrives.

Maintaining a compression depth of at least 2 inches helps to ensure that the heart is sufficiently compressed, facilitating better blood flow during the critical moments of cardiac arrest. Research and guidelines from organizations such as the American Heart Association underline the importance of achieving this depth to maximize the effectiveness of CPR, thereby increasing the likelihood of a positive outcome for the patient.
