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.

lymph nodes in the chest, or to treat problems such as
an object or growth in the airway.

You will be asked to sign a consent form that says you understand the risks of the test and agree to have it done.
Talk to your doctor about any concerns you have
regarding the need for the procedure, its risks, how it will be done, or what

Your doctor will tell you how soon before the biopsy to stop eating and drinking. Follow the instructions exactly about when to stop eating and drinking, or your test may be canceled. If your doctor has instructed you to take your medicines on the day of surgery, please do so using only a sip of water.
Your doctor may order other tests before your bronchoscopy,
such as a
complete blood count (CBC), clotting factors,
arterial blood gas (ABG), or
lung function tests.
Arrange to have
someone drive you home after the procedure.
You may be asked to remove dentures,
eyeglasses or contact lenses, hearing aids, wigs, makeup, and jewelry before
the bronchoscopy procedure. You will empty your bladder before the procedure.
You will need to take off all or most of your clothes (you may be allowed to
keep on your underwear if it does not interfere with the procedure). You will
be given a cloth or paper covering to use during the procedure.
The procedure is done by a
pulmonologist and an assistant. Your heart rate, blood
pressure, and oxygen level will be checked during the procedure.
A chest X-ray may be done before and after the bronchoscopy.
During this procedure, you

your throat and reduces your gag reflex during the procedure. If the
bronchoscope is to be inserted through your nose, your doctor may also place an
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

aches. If a local anesthetic is used, you may have a bitter taste in your
mouth. Your mouth may feel very dry for several hours after the procedure. You
