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.
Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument ( bronchoscope ) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy .
Bronchoscopy is the most effective method to diagnose, locate, and determine the severity of TBI, [6] [10] and it is usually the only method that allows a definitive diagnosis. [23] Diagnosis with a flexible bronchoscope, which allows the injury to be visualized directly, is the fastest and most reliable technique. [8]
Stanford University medical professor Dr. Bryant Lin was diagnosed with stage IV lung cancer despite never smoking. Now, he's using himself as a case study to teach students about patient care.
Evaluation by means of bronchoscopy can be difficult and time consuming and is best performed under general anesthesia. Casts can be removed mechanically by bronchoscopy or physical therapy. High-frequency chest wall oscillation can also be used to vibrate the chest wall at a high frequency to try to loosen and thin the casts.
Lin, who is the co-founder of Stanford’s Center for Asian Health Research and Education (CARE), has dedicated a lot of his career to researching lung cancer specifically among Asian American non ...
Rigid bronchoscopy allows good airway control, ready bleeding management, better visualization, and ability to manipulate the aspirated object with a variety of forceps. [14] Flexible bronchoscopy may be used for extraction when distal access is needed and the operator is experienced in this technique. [ 14 ]
According to the federal government’s Center for Disease Control, the risk of developing lung cancer drops by half within 10 to 15 years after quitting. Meanwhile, the risk of developing ...
