Diagram 2: Bronchoscopy 
You will be sedated with a medication given by vein, and a local anesthetic used to 
numb your nose and throat. A flexible lighted tube, called a bronchoscope, is passed 
through your nose, down the throat, and into the right lung bronchus. The opening 
of the bronchoscope is then advanced into the right lower lobe bronchus, and fluid 
and cells are removed for analysis. A salt-water solution or the gene therapy virus 
is then injected, and the bronchoscope is removed. The whole procedure takes 
60-90 minutes.
