In prehospital care, which finding indicates a tension pneumothorax?

• A. Severe unilateral chest pain and dyspnea with absent/decreased breath sounds on the affected side.
• B. Chest pain on both sides with clear breath sounds.
• C. Severe unilateral chest pain and dyspnea, absent/decreased breath sounds on affected side, tracheal deviation (late), distended neck veins.
• D. Stable vitals with no chest findings.

Answer: (C)

Tension pneumothorax occurs when air trapped in the chest under pressure pushes the lung apart and shifts the mediastinum, which severely compromises breathing and the return of blood to the heart. The key clue is a combination of signs that show both lung collapse on one side and pressure effects inside the chest. Severe unilateral chest pain and dyspnea with absent or decreased breath sounds on the affected side indicate a major lung problem on that side, but the real red flags for tension are the later signs of mediastinal shift, such as tracheal deviation, and distended neck veins from impaired venous return. When you see both absent/decreased breath sounds on one side along with tracheal deviation and neck vein distention, it points to a tension pneumothorax rather than a simple pneumothorax or other chest issue. The other patterns—bilateral chest pain with clear breath sounds or stable vitals with no chest findings—do not reflect the pressure buildup and mediastinal shift that define tension pneumothorax.
