What is the recommended depth of chest compressions for adults during CPR?

The recommended depth of chest compressions for adults during CPR is at least 2 inches deep. This guideline is based on evidence showing that deeper compressions are more effective in generating blood flow and improving the chances of survival in a cardiac arrest situation. When delivering compressions, it is crucial to achieve the appropriate depth to ensure that the heart is adequately compressed, allowing for effective circulation.

The 2-inch depth helps optimize the pressure exerted on the heart while minimizing the risk of injury to the patient's thoracic structures. The recommendations are grounded in studies of CPR performance that indicate this depth is effective in both adult and adolescent patients. Adhering to this standard is vital for first responders to provide the best possible care in a life-threatening scenario.
