Which condition may worsen if a tension pneumothorax is not addressed?

• A. Hypotension
• B. Pneumonia
• C. Cerebral edema
• D. Shock

Answer: (D)

A tension pneumothorax, if not addressed, can lead to a progressive decline in respiratory and cardiovascular function, ultimately resulting in shock. This occurs because the accumulation of air in the pleural space increases intrathoracic pressure, which impedes venous return to the heart. As venous return decreases, cardiac output falls, leading to reduced perfusion of vital organs and tissues. The body's compensatory mechanisms may initially maintain blood pressure, but as the tension builds and organ perfusion decreases, the situation deteriorates further, and shock can ensue. Addressing a tension pneumothorax is critical to restoring normal intrathoracic pressure, allowing for adequate respiratory function and enabling the heart to effectively pump blood, which is fundamental in preventing or reversing shock.
