Question: 1 / 400

During ACLS, what is the recommended depth for adult chest compressions?

At least 1 inch

At least 2 inches

The recommended depth for adult chest compressions during ACLS is at least 2 inches. This depth is critical for generating adequate pressure to create enough blood flow to vital organs during a cardiac arrest situation. The emphasis on at least 2 inches ensures that compressions are effective in facilitating circulation, which is pivotal for the survival of the patient.

Compressing to this depth helps optimize the intrathoracic pressure and improves coronary perfusion pressure during compressions. It aligns with the guidelines set by organizations such as the American Heart Association, which have reviewed evidence demonstrating that 2 inches is sufficient for achieving the goal of effective compressions while minimizing the risk of injury.

Understanding this guideline is essential, as chest compressions that are too shallow may not provide sufficient blood flow to the heart and brain, significantly reducing the chances of a successful resuscitation.
