What causes atelectasis

Atelectasis occurs from a blocked airway (obstructive) or pressure from outside the lung (nonobstructive). General anesthesia is a common cause of atelectasis. It changes your regular pattern of breathing and affects the exchange of lung gases, which can cause the air sacs (alveoli) to deflate.

Atelectasis is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the outside of the lung
