Bronchoscopy is a procedure that allows your
doctor to look at your airway through a thin viewing instrument called a
bronchoscope. During a bronchoscopy, your doctor will examine your throat,
trachea, and lower airways.

complete blood count (CBC), clotting factors,
arterial blood gas (ABG), or
lung function tests.

anesthetic ointment in your nose to numb your nasal passages.
doctor gently and slowly inserts the thin bronchoscope through your mouth (or
nose) and advances it to the vocal cords. Then more anesthetic is sprayed
through the bronchoscope to numb the vocal cords. You may be asked to take a
deep breath so the scope can pass your vocal cords. It is important to avoid
trying to talk while the bronchoscope is in your airway.

any devices, such as
forceps to collect a biopsy sample, that are being
moved into your lung. The bronchoscope is then moved down your larger breathing
tubes (bronchi) to examine the lower airways.
If your doctor
collects sputum or tissue samples for biopsy, a tiny biopsy tool or brush will
be used through the scope. A salt (saline) fluid may be used to wash your
airway, then the samples are collected and sent to the lab to be
