Alternative Names
Partial lung collapse
Causes, incidence, and risk factors
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:
- Anesthesia
- Foreign object in the airway (most common in children)
Lung diseases - Mucus that plugs the airway
- Pressure on the lung caused by a buildup of fluid between the ribs and the lungs (called a
pleural effusion ) - Prolonged bed rest with few changes in position
- Shallow breathing (may be caused by painful breathing)
-
