Atelectasis and Collapse conditions
Atelectasis (Compressive)Compressive atelectasis occurs when external pressure collapses lung tissue, often due to pleural effusion or tumor, impairing ventilation and gas exchange.Atelectasis (Contraction/Cicatrization)Atelectasis (Contraction/Cicatrization) is lung collapse due to fibrotic scarring that restricts expansion, often following chronic inflammation or injury.Atelectasis (Obstructive)Atelectasis (Obstructive) involves lung collapse due to airway obstruction, leading to reduced ventilation, hypoxia, and characteristic findings on chest imaging.
