These physical injury mechanisms are frequently modeled in vitro with mechanical cyclic stretch using lung epithelial or … WebOverview Atelectasis (at-uh-LEK-tuh-sis) is a complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. Atelectasis is one of the most common breathing (respiratory) complications after surgery.

WebAtelectasis happens when lung sacs (alveoli) can’t inflate properly, which means blood, tissues and organs may not get oxygen. It can be caused by pressure outside of your lung, a blockage, low airflow or scarring. The most common cause of atelectasis is surgery with anesthesia.
