This document discusses the importance and benefits of debriefing after cardiac arrest events. It notes that debriefing improves CPR performance and results in higher rates of return of spontaneous circulation. Debriefing allows rescuers to reflect on their performance, identify areas for improvement, and learn from real-life events. When used as part of an organized resuscitation response system or as part of advanced life support courses, debriefing has been shown to improve adherence to guidelines and result in better performance during subsequent simulated scenarios. The document advocates for incorporating structured and supported debriefing into the resuscitation process to help clinicians evaluate what happened, how they responded, and how they can enhance outcomes going forward.
