Which statement is true about the depth of compressions on an adult?

The statement regarding the depth of compressions on an adult is accurate, as adult CPR guidelines specify that compressions should be delivered at a depth of 2 inches to 2.4 inches. This depth is crucial because it allows adequate blood flow to vital organs, particularly the heart and brain, during cardiac arrest. Compressions that are too shallow may not generate sufficient pressure to maintain blood circulation, while compressions that are too deep may increase the risk of injury to the ribs or other internal structures.

Establishing this specific range ensures that responders can effectively perform CPR to maximize the chances of survival and promote recovery until advanced medical help arrives. Therefore, adhering to the guideline of 2 inches to 2.4 inches is essential for effective resuscitation efforts.
