How deep should chest compressions be for adults?

For adult patients, chest compressions during CPR should be performed to a depth of at least 2 inches. This depth is critical for generating adequate pressure within the chest cavity to effectively circulate blood to vital organs like the brain and heart. Compressions that are too shallow may not sufficiently compress the heart, thereby reducing the effectiveness of CPR in achieving blood flow.

The recommendation of at least 2 inches is supported by guidelines from organizations such as the American Heart Association, which emphasize the importance of sufficient compression depth to ensure proper perfusion. In addition, compressing the chest to this depth allows for the optimal return of the chest wall, which is essential for effective venous return to the heart between compressions.

In summary, maintaining a compression depth of at least 2 inches is crucial to enhance the chances of survival during cardiac arrest, making this the appropriate standard for adult CPR.
