When should rescuers begin medical evaluation and treatment for victims during an extrication?

Rescuers should begin medical evaluation and treatment for victims immediately upon access because this approach maximizes the chances of survival and minimizes the potential for further harm. Conducting a medical assessment as soon as rescuers can safely access the victims allows for the identification of life-threatening conditions and the administration of critical care without unnecessary delays.

Beginning the medical evaluation promptly also helps in establishing priorities for treatment, especially in scenarios where multiple victims may be present. While rescuers must ensure their own safety and the safety of the scene, once access is achieved, providing initial care is crucial. Waiting for extrication to be completed or for all victims to be identified could result in critical delays for those who may need immediate medical attention, such as those experiencing severe bleeding, respiratory distress, or other emergent conditions. This proactive approach is essential for effective emergency response during vehicle rescues.
