After identifying JVD in trauma, which sign helps differentiate pericardial tamponade from a tension pneumothorax?

• A. Breath sounds clear bilaterally in tamponade
• B. Absent breath sounds on the affected side in tamponade
• C. Tracheal deviation toward the affected side in tamponade
• D. Hyper-resonance on the affected side in tamponade

Answer: (A)

In trauma assessment, telltale lung findings help separate tamponade from a tension pneumothorax. Pericardial tamponade impedes heart filling but doesn’t usually disturb the lungs, so breath sounds remain clear on both sides. Tension pneumothorax, however, causes air buildup in the pleural space on the affected side, leading to diminished or absent breath sounds, often with hyper-resonance and potential tracheal shift away from the side of injury. So, hearing clear breath sounds bilaterally points toward tamponade rather than tension pneumothorax.
