A collapsed lung
(pneumothorax) is a buildup of air in the space between the lung and the chest
wall (pleural space). As the amount of air in this space increases, the
pressure against the lung causes the lung to collapse. This prevents your lung
from expanding properly when you try to breathe in, causing shortness of breath
and chest pain.
A pneumothorax may become life-threatening if
the pressure in your chest prevents the lungs from getting enough oxygen into

Doctors may classify lung conditions as obstructive lung disease or restrictive lung disease. Obstructive lung diseases include conditions that make it hard to exhale all the air in the lungs. People with restrictive lung disease have difficulty fully expanding their lungs with air.
Obstructive and restrictive lung disease share the same main symptom: shortness of breath with exertion.
