Which of the following is NOT included in the 'deadly dozen' list of traumatic injuries?

The 'deadly dozen' refers to a specific list of critical traumatic injuries that are often associated with high mortality rates when not promptly recognized and treated. These injuries are significant due to their potential to lead to rapid deterioration of the patient's condition.

Cardiac arrest, while a life-threatening condition, typically occurs as a consequence of other underlying injuries or medical issues rather than being classified as a direct traumatic injury itself. The other options—Aortic Rupture, Massive Hemothorax, and Flail Chest—are all serious traumatic injuries that can directly arise from blunt or penetrating trauma and are known to contribute significantly to early mortality if not addressed immediately.

Understanding these distinctions helps paramedics prioritize their assessments and interventions during trauma care. Identifying and managing the 'deadly dozen' focuses on rapid stabilization of major life-threatening injuries, while cardiac arrest requires specific resuscitation efforts related to its cardiac origin.
