The Univent tube is a conventional ETT with a second lumen containing a small tube that can be advanced into a bronchus. A balloon located at the distal end of this small tube, when inflated, serves as a bronchial blocker. Univent tubes require FOB for successful placement. Univent tubes are now available in sizes as small as a 3.5 and 4.5 mm internal diameter for children (16).
Because the blocker tube is firmly attached to the main ETT, displacement of the Univent blocker balloon is less likely than when other blocker techniques are used. refl.in/lr
