Atelectasis

Term: AtelectasisDefinition: Atelectasis is the collapse or incomplete expansion of a lung or portion of a lung, which can result from obstruction of the airways, compression from outside the lung, or lack of surfactant.Phonetic Pronunciation: (at-uh-LEK-tuh-sis)Origin: The term 'atelectasis' originates from the Greek words 'atelēs', meaning 'incomplete', and 'ektasis', meaning 'expansion'. It was first used in medical literature in the 19th century to describe a condition observed in autopsies and later recognized in living patients through imaging techniques.Significance in Asbestos Context: Atelectasis can be a secondary condition in asbestos-related diseases such as asbestosis or lung cancer. It is significant because it can exacerbate respiratory issues in individuals already suffering from asbestos-induced lung damage, complicating their medical condition and prognosis.Example Sentence: The patient's chest X-ray revealed atelectasis, which was attributed to the scarring caused by his long-term exposure to asbestos fibers.Related Terms: Asbestosis, Pleural Effusion, Lung Cancer, Pneumonia, Respiratory FailureNotes: - Atelectasis can be reversible if the underlying cause is treated promptly. - It is not a disease itself but a condition that can result from various underlying issues, including asbestos exposure.
