Lung Collapse (Atelectasis)
Atelectasis means part of the lung is not expanding fully, which can happen after surgery, blockage, shallow breathing, or other chest problems.
When to get help quickly: Prompt review is important if breathlessness is worsening, oxygen level is low, fever develops, or the collapse may be due to a blocked airway.
Common symptoms
Some people have no symptoms, but others may have shortness of breath, chest discomfort, cough, or low oxygen levels, especially if a larger part of the lung is affected.
When imaging helps
Imaging helps show which part of the lung is not opening properly and whether the cause may be mucus, infection, shallow breathing, or a blockage in the airway.
What radiology does
Chest X-ray and CT can help show which part of the lung is affected and whether there is an underlying cause such as mucus plugging or a mass.
What usually happens next
Treatment depends on the cause and may involve breathing exercises, physiotherapy, suctioning, or further evaluation of a blockage.
