7. Keeping the bronchoscope position stable (loosen guide
loop if snare is cinched onto bronchoscope), advance the
endobronchial blocker until the guide loop disengages
from the bronchoscope. (Fig. 4)
8. Retract the bronchoscope. The endobronchial blocker
may be either advanced or retracted to place the balloon
within either the right or left mainstem bronchus. (Fig. 5)
9. Place patient in final position. Under bronchoscopic
vision, inflate the balloon with air using the pilot balloon
assembly. The balloon should fill the entire endobronchial
lumen to be blocked and not herniate into the mainstem
trachea. Do not overinflate balloon. (Fig. 6)
