Multiple Choice

Delayed death due to trauma is usually a result of:**

The main idea is that a patient’s survival after the initial trauma can be followed by deterioration caused by not getting enough oxygen. When ventilation or oxygen delivery falters—due to airway compromise, chest injuries, or evolving respiratory failure—the body’s tissues, especially the brain, begin to suffer from hypoxia. This lack of oxygen drives progressive cellular injury and organ failure, which often manifests as delayed death hours after the injury, even if the initial injuries were survived. While circulatory collapse or brain injury can be fatal, the pattern most associated with late deterioration in trauma is ongoing hypoxia from inadequate oxygenation.
