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 likely won't cause signs or symptoms if it only affects a small area of lung. If atelectasis affects a large area of lung, especially if it occurs suddenly, it may cause a low level of oxygen in your blood. As a result, you may feel short of breath. Your heart rate and breathing rate may increase, and your skin and lips may turn blue.
