Pneumothorax I lung physiology I pulmonary medicine part 1

“Pneumothorax” is the medical term for a collapsed lung. Pneumothorax occurs when air enters the space around your lungs (the pleural space). Air can find its way into the pleural space when there’s an open injury in your chest wall or a tear or rupture in your lung tissue, disrupting the pressure that keeps your lungs inflated. Causes of ruptured or injured chest or lung walls can include lung disease, injury from a sport or accident, assisted breathing with a ventilator, or even changes in air pressure that you experience when scuba diving or mountain climbing. Sometimes the cause of a pneumothorax is unknown. The change in pressure caused by an opening in your chest or lung wall can cause the lung to collapse and put pressure on the heart. The condition ranges in severity. If there’s only a small amount of air trapped in the pleural space, as can be the case in a spontaneous pneumothorax, it can often heal on its own if there have been no further complications. More serious cases that involve larger volumes of air can become fatal if left untreated.
