Partial lung collapse
Atelectasis is the collapse of part or (much less commonly) all of a lung.
See also: Pneumothorax
Atelectasis is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the outside of the lung.
It is common after surgery, or in patients who were in the hospital.
Risk factors for developing atelectasis include:
