WebCollapsed Lung (Pneumothorax) A collapsed lung occurs when air gets inside the chest cavity (outside the lung) and creates pressure against the lung. Also known as pneumothorax, collapsed lung is a rare condition that may cause chest pain and make it hard to breathe. A collapsed lung requires immediate medical care. 216.444.6503. WebHMD occurs when there is not enough of a substance in the lungs called surfactant. Surfactant is made by the cells in the airways and consists of phospholipids and protein. It begins to be produced in the fetus at about 24 to 28 weeks of pregnancy, and is found in amniotic fluid between 28 and 32 weeks.

WebThe most common cause is called respiratory distress syndrome (RDS). In RDS, the infant’s immature or stressed lungs do not produce enough of an important substance called surfactant. Surfactant enables the lungs to expand more easily. Without surfactant, the air sacs in the lungs, also called alveoli, collapse very easily.
