When you breathe, air passes through your trachea and bronchi and into
your lungs. A bronchoscopy lets your doctor examine these airways and
take samples of lung fluids and tissues.
How should I prepare for bronchoscopy?
Do not eat or drink anything after midnight the night before the test,
unless told otherwise by your doctor. Do not smoke for at least 48 hours
before the test. You may be given a sedative 30-60 minutes before the
test or during the test. This will help you relax.
A local anesthetic spray may be used to numb your nose and throat. If you have had any allergic reaction to local anesthesia, let your doctor and nurse know before the procedure.
