How many types of atelectasis are there?

The two main types of atelectasis are obstructive (also called resorptive) and nonobstructive.

Which type of atelectasis is the most common?

Obstructive atelectasis is the most common type and results from reabsorption of gas from the alveoli when communication between the alveoli and the trachea is obstructed. The obstruction can occur at the level of the larger or smaller bronchus.

What is atelectasis PDF?

Atelectasis. MARY ELLEN BECK WOHL, M.D. IATELECTASIS is a condition in. which lung tissue is collapsed and empty of air. The condition may be focal or patchy with small groups of airless alveoli surrounded by aerated alveoli, or an entire lung segment or lobe may be collapsed.

What is Subsegmental atelectasis?

Terminology. The term subsegmental atelectasis includes any loss of lung volume so small that it does not cause indirect signs of volume loss (as might be seen with larger atelectases).

What classification is atelectasis?

Atelectasis can categorize into obstructive, non-obstructive, postoperative, and rounded atelectasis. Nonobstructive atelectasis can further classify into compression, adhesive, cicatrization, relaxation, and replacement atelectasis.

What is Bibasilar atelectasis?

Bibasilar atelectasis is a condition that happens when you have a partial collapse of your lungs. This type of collapse is caused when the small air sacs in your lungs deflate. These small air sacs are called alveoli. Bibasilar atelectasis specifically refers to the collapse of the lower sections of your lungs.

What is atelectasis?

Atelectasis, the collapse of part or all of a lung, is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the lung. Risk factors for atelectasis include anesthesia, prolonged bed rest with few changes in position, shallow breathing and underlying lung disease.

What is left basal Subsegmental atelectasis?

What is discoid atelectasis?

linear (a.k.a. plate, band, discoid) atelectasis: a minimal degree of collapse as seen in patients who are not taking deep breaths (“splinting”), such as postoperative patients or patients with rib fracture or pleuritic chest pain; this is very common. round atelectasis: classically associated with asbestos exposure.

What is Subsegmental atelectasis in right middle lobe?

The term subsegmental atelectasis includes any loss of lung volume so small that it does not cause indirect signs of volume loss (as might be seen with larger atelectases).
