What best describes tension pneumothorax?

• A. It is life threatening
• B. It is not life threatening
• C. It is a mild condition
• D. It is rare

Answer: (A)

Tension pneumothorax is a life-threatening emergency caused by air that accumulates under pressure in the pleural space. That trapped air pushes the lung to collapse and shifts the mediastinal structures toward the opposite side. The pressure compresses the great vessels, dramatically reducing venous return to the heart, which rapidly drops cardiac output and can lead to shock and Peru’s oxygenation failure. Because the condition can deteriorate within minutes, it demands immediate intervention rather than waiting for imaging or radiographic confirmation. Clinically, you’d expect sudden, severe shortness of breath, rapid pulse, and low blood pressure, often with distended neck veins and possibly tracheal deviation away from the affected side. Breath sounds on the affected side may be reduced or absent, and the chest may be hyperresonant to percussion. If treated promptly with emergency needle decompression followed by chest tube placement, the patient’s condition can stabilize quickly; delays can be fatal. This description distinguishes tension pneumothorax from less severe pneumothorax forms, which do not produce the same rapid cardiopulmonary compromise.
