During a fall, chest impact may cause traumatic asphyxia. Which finding supports this suspicion?

• A. Seizures
• B. Shortness of breath
• C. Coughing up blood
• D. Nausea

Answer: (C)

Traumatic asphyxia occurs when a strong chest impact abruptly raises intrathoracic pressure, causing tiny blood vessels in the lungs and airways to rupture. That vascular disruption can lead to bleeding into the airways, so coughing up blood (hemoptysis) is a direct sign of pulmonary injury from chest trauma and supports the suspicion of traumatic asphyxia. The other options are less specific to chest compression injuries: seizures relate to brain issues, shortness of breath can occur for many reasons, and nausea isn’t a distinct feature of this mechanism.
