Which symptom is associated with tension pneumothorax?

• A. Distant heart sounds
• B. Absent breath sounds
• C. Hypotension
• D. JVD

Answer: (B)

In the context of tension pneumothorax, the presence of absent breath sounds on the affected side is a key finding. Tension pneumothorax occurs when air enters the pleural space and cannot escape, leading to increased intrathoracic pressure. This pressure can compress the lung on the affected side, resulting in a reduction or absence of breath sounds during auscultation.

When the lung is compressed, and air fills the pleural space, the ventilation of that lung segment becomes limited or stops entirely, which is why breath sounds might be absent. The other signs associated with tension pneumothorax include jugular venous distension (due to increased central venous pressure), hypotension (as a result of compromised venous return to the heart), and possibly distant heart sounds, but those do not directly relate to the auscultation findings that indicate absent breath sounds in the affected lung field.

Recognizing absent breath sounds as a critical indicator can help in the timely diagnosis and management of tension pneumothorax, emphasizing the need for immediate decompression to prevent further cardiovascular compromise.
