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.
Hypoventilation is the most common cause of atelectasis, especially after chest surgery. Airway obstruction may be caused when something blocks a passage either inside the lung (like mucus or a foreign object) or outside of the lungs (like a tumor which press on the airway and cause obstruction).
