Bronchoscopy is a way of inspecting the airways (trachea and bronchi) for diagnostic or therapeutic purposes.
The bronchoscope is inserted into the airways, through the nose or mouth. This way the pulmonologist examines the patient’s lungs for abnormalities and diseases such as tumors, bleeding, inflammation and infections. Specimens are usually taken either with forceps or with lavage.
It is routine procedure with minimal adverse effects if performed by experienced chest physicians. It lasts only 10-15, without any special preparations. For safety reasons though, it is only performed in clinics or hospitals.
