The document discusses the ATLS (Advanced Trauma Life Support) concept for managing trauma. It describes ATLS as an internationally recognized system that teaches a methodical approach to rapidly assess and treat life-threatening injuries in trauma patients. The steps include: (1) conducting a primary survey to evaluate the patient's airway, breathing, circulation, disability and exposure; (2) performing a secondary survey involving a full physical exam and history; and (3) re-evaluating the patient to ensure all injuries are identified and managed. The goal of ATLS and trauma management overall is to prevent death by treating life-threatening conditions as the top priority, especially within the "Golden Hour" period after injury.
