What can happen if tension pneumothorax is not treated promptly?

• A. It may resolve on its own
• B. It may lead to respiratory distress and shock
• C. It can improve with time
• D. It reduces blood flow to the brain

Answer: (B)

When tension pneumothorax is not treated promptly, it can result in serious complications such as respiratory distress and shock. This condition occurs when air becomes trapped in the pleural space and increases intrathoracic pressure, which can collapse the affected lung and push the mediastinum (the central compartment of the thoracic cavity) toward the opposite side. As a result, the heart and great vessels can be compromised, leading to decreased blood return to the heart and reduced cardiac output. This cascade of events triggers respiratory distress due to inadequate ventilation and ultimately shock due to insufficient blood flow to vital organs. Therefore, immediate intervention is critical to relieve the pressure and restore normal respiratory and cardiovascular function.
