What is the appropriate compression depth for adult CPR?

The appropriate compression depth for adult CPR is at least 2 inches (5 cm). This depth ensures that effective compressions are delivered to promote adequate blood flow to the brain and vital organs during cardiac arrest. Compressions that are too shallow may not generate sufficient pressure to circulate blood effectively, reducing the chances of meaningful outcomes for the patient.

Current guidelines emphasize the importance of pushing hard and fast, aiming for a depth that allows for full chest recoil to enhance blood return to the heart. The threshold of 2 inches strikes a balance between maximizing blood flow and minimizing the risk of injury to the patient, as compressions that are too deep could potentially cause thoracic injuries. Therefore, maintaining this compression depth is crucial for successful resuscitation efforts.
