Is atelectasis a medical diagnosis?
A doctor’s examination and plain chest X-ray may be all that is needed to diagnose atelectasis. However, other tests may be done to confirm the diagnosis or determine the type or severity of atelectasis. They include: CT scan.

When these efforts are not successful within 24 hours, flexible fiberoptic bronchoscopy could be performed.
What happens if you have lobar atelectasis?
Lobar atelectasis (or collapse) is an exceedingly common, rather predictable, and potentially pathogenic companion to many forms of acute illness, postoperative care, and chronic debility.

How is acute lobar collapse treated in intensive care?
Distribution and pathophysiology of acute lobar collapse in the pediatric intensive care unit. They also have less well-developed collateral ventilation and compressible, small-diameter bronchi. The bronchi are also oriented differently among young children, favoring mucus clogging of the dependent upper lobe.
How is reabsorption atelectasis related to Ards?
Reabsorption atelectasis in a porcine model of ARDS: regional and temporal effects of airway closure, oxygen, and distending pressure. To sigh or not to sigh?. Lung collapse during low tidal volume ventilation in acute respiratory distress syndrome.
Why does lobar collapse on the left side?
The narrower main bronchus serving the left lung angulates more sharply and divides more peripherally than that serving the right. When semi-upright, gravity predisposes mucus to collect dependently. Collapse of the lower lobe occurs approximately twice as commonly on the left as on the right, Lobar collapse in the surgical intensive care unit.
