The Duty to Respond (DTR) course is a trauma management program developed by ITLS (International Trauma Life Support) for first responders who are trained to provide immediate, life-saving care in emergencies. This course focuses on the initial trauma assessment and management techniques required in the critical moments before advanced medical help arrives.

DTR is ideal for first responders, volunteer rescuers, and public safety personnel who may be the first on the scene in trauma situations.
