There are 4 primary mechanisms that can cause atelectasis. These include: Obstruction - Blockage of an airway, either from inside (for example, by a foreign body that is aspirated, or a mucous plug), or the outside (for example, by a lung cancer pressing on the airway), can result in collapse of a portion of the lung.
Atelectasis can also be caused by trauma to the lungs, a buildup of mucus, or an obstruction such as a foreign object or tumor. In congenital atelectasis, an infant is born without the ability to inflate one or both lungs.
