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 .
The internal air is forced out so that negative air pressure is created pulling air passively into the system from other inlets. Negative room pressure is an isolation technique used in hospitals and medical centers to prevent cross-contamination from room to room.
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.
Rigid bronchoscopy allows good airway control, ready bleeding management, better visualization, and ability to manipulate the aspirated object with a variety of forceps. [23] Flexible bronchoscopy may be used for extraction when distal access is needed and the operator is experienced in this technique. [23]

A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, [1] [2] in order to determine the ventilation/perfusion ratio.
The treatment, called injection lipolysis, can expensive when performed by a board-certified dermatologist—Rabach estimates it’ll set you back around $1,500—and price could be one reason ...
Any approach to lung biopsy risks causing a pneumothorax.Careful technique can limit this risk, which ranges from less than 1% to about 10%. The precise risk of pneumothorax depends on technique and on underlying lung disease, as certain lung diseases such as COPD can increase the risk of pneumothorax.
