What is linear atelectasis in lungs?

Linear atelectasis is a focal area of subsegmental atelectasis with a linear shape. It is normally horizontal and sometimes oblique or perpendicular. Linear atelectasis may occur as a consequence of obstruction in the bronchus of a pulmonary subsegment.

Is linear atelectasis serious?

When you breathe in and out, your lungs inflate and deflate like balloons. But if your airways get blocked or something puts pressure on your lungs, they might not inflate the way they should. Doctors call that condition atelectasis. It can be life-threatening in small children or people who have another lung problem.

What is atelectasis in chest X ray?

Definition of Atelectasis: On x-rays and CT scans, reduced volume is seen, accompanied by increased opacity (chest radiograph) or attenuation (CT scan) in the affected part of the lung. Atelectasis is often associated with abnormal displacement of fissures, bronchi, vessels, diaphragm, heart, or mediastinum.

Is linear atelectasis common?

Linear atelectasis may appear to be horizontal, oblique or perpendicular and is very common. It usually occurs as a consequence of subsegmental bronchial obstruction and can resolve as quickly as it occurs.

How is linear atelectasis treated?


  1. Performing deep-breathing exercises (incentive spirometry) and using a device to assist with deep coughing may help remove secretions and increase lung volume.
  2. Positioning your body so that your head is lower than your chest (postural drainage).
  3. Tapping on your chest over the collapsed area to loosen mucus.

What causes linear 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.

Is linear atelectasis pneumonia?

Atelectasis makes it more difficult for your lungs to get oxygen to the air sacs (alveoli). Pneumonia. Your risk for pneumonia continues until the atelectasis goes away. Mucus in a collapsed lung may lead to infection.

Can mild atelectasis go away?
