Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
Whole lung lavage (WLL), also called lung washing, is a medical procedure in which the patient's lungs are washed with saline (salt water) by filling and draining repeatedly. It is used to treat pulmonary alveolar proteinosis , in which excess lung surfactant proteins prevent the patient from breathing.
Lipid-laden alveolar macrophages in a case of vaping-associated pulmonary injury.Left: Papanicolaou stain; right: Oil Red O stain. [1]Lipid-laden alveolar macrophages, also known as pulmonary foam cells, [2] are cells found in bronchoalveolar lavage (BAL) specimens that consist of macrophages containing deposits of lipids (fats).

Additionally, pentamidine does not reach curative levels in the cerebrospinal fluid. [10] It has a volume of distribution of 286-1356 liters when given intravenously and 1658-3790 liters when given intramuscularly. [20] Inhaled pentamidine is mainly deposited into the bronchoalveolar lavage fluid of the lungs. [19]
A sputum culture is a test to detect and identify bacteria [1] or fungi that infect the lungs or breathing passages. Sputum is a thick fluid produced in the lungs and in the adjacent airways.
The sterile fungi, or mycelia sterilia, are a group of fungi that do not produce any known spores, either sexual or asexual.This is considered a form group, not a taxonomic division, and is used as a matter of convenience only, as various isolates within such morphotypes could include distantly related taxa or different morphotypes of the same species, [1] leading to incorrect identifications.
A bronchoalveolar lavage can show an elevated (of at least 3.5) CD4/CD8 T cell ratio, which is indicative (but not proof) of pulmonary sarcoidosis. [26] In at least one study the induced sputum ratio of CD4/CD8 and level of TNF was correlated to those in the lavage fluid. [102]
Pulmonology (/ ˌ p ʌ l m ə ˈ n ɒ l ə dʒ i /, / ˌ p ʊ l m ə ˈ n ɒ l ə dʒ i /, from Latin pulmō, -ōnis "lung" and the Greek suffix -λογία-logía "study of"), pneumology (/ n ʊ ˈ m ɒ l ə dʒ i, n j ʊ-/, built on Greek πνεύμων pneúmōn "lung") or pneumonology [1] (/ n ʊ m ə n ˈ ɒ l ə dʒ i, n j ʊ-/) is a medical specialty that deals with diseases involving ...
