Jul 30, 2025 · Absorption atelectasis occurs when small pockets of air remain trapped within non-ventilated alveoli. The oxygen and carbon dioxide within these alveoli are gradually …

Jun 19, 2023 · The mechanism by which atelectasis occurs is due to one of three processes: compression of lung tissue (compressive atelectasis), absorption of alveolar air (resorptive …

Atelectasis happens when lung sacs (alveoli) can’t inflate properly. The most common cause of atelectasis is surgery that requires anesthesia.

The literature was reviewed to determine the incidence of absorption atel-ectasis during induction and maintenance of anesthesia as well as the effect of attempts at reversal of anesthesia …

absorption atelectasis (acquired atelectasis) that produced by any factor, e.g., secretions, foreign body, tumor, or abnormal external pressure, that completely obstructs the airway, preventing …

Jul 3, 2025 · The classification of atelectasis according to the pathophysiologic mechanism is reviewed here, as are the mechanisms of each type of atelectasis. Radiologic manifestations …

If a large volume of nitrogen in the lungs is replaced with oxygen, the oxygen may subsequently be absorbed into the blood, reducing the volume of the alveoli, resulting in a form of alveolar …

Nov 8, 2023 · Atelectasis (at-uh-LEK-tuh-sis) is the collapse of a lung or part of a lung, also known as a lobe. It happens when tiny air sacs within the lung, called alveoli, lose air. Atelectasis is …

Atelectasis (pronounced at-uh-LEK-tuh-sis) happens when the tiny air sacs or alveoli in your lungs are blocked, and it causes a partial or full collapse of one or more lobes or sections of the …

Nov 11, 2025 · Low alveolar pressure is the main mechanism behind obstructive atelectasis, but airway occlusion may also contribute to absorption atelectasis. Low alveolar pressure can …
