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.
Obtaining targeted deep respiratory samples by bronchoalveolar lavage or protected specimen brush for the diagnosis or exclusion of pneumonia; Evaluation of alveolar cytopathology to identify inflammatory conditions or Alveolar haemorrhage; Direct inspection of the tracheal muscoa for pulmonary aspergillosis or similar invasive mould infections
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.
Bronchoalveolar lavage (BAL) is a procedure whereby a small volume of fluid is put into the airways in order sample the cells and fluids of the alveoli and epithelium of the bronchi. [23] BAL may be performed using a BAL tube, which allows fluid to be added to and removed from the bronchi, or may be performed during endoscopy, if the endoscope ...
[9] [10] Dilution is an issue that is a problem with all methods of sampling the airway and lungs including sputum collection and bronchoalveolar lavage. Suggestions to allow for dilution include using a denominator such as protein, urea or conductivity, [ 11 ] but no single method is universally accepted at present.

The presence of emphysema is a clear risk factor for lung cancer, made stronger in those who smoke. [20] Early symptoms of emphysema vary. They can include a cough (with or without sputum), wheezing, a fast breathing rate, breathlessness on exertion, and a feeling of tightness in the chest. There may be frequent cold or flu infections.

Flexible bronchoscopy is often used to gather samples of bronchoalveolar lavage for quantitative bacteriological tests as well as high volume aspiration to clear the secretion. [25] In general practice The main treatment of aspiration pneumonia revolves around the use of antibiotics to remove the bacteria causing the infection. [ 1 ]
