Intubate as usual with an endotracheal (ET) tube size 7.0 mm or larger. Attach the EZ-Multiport Adaptor.

Confirm depth of intubation, leaving 4 cm between distal tip of the ET tube and the carina to allow sufficient space for the deployment of the bifurcated tips.

Insert the EZ-Blocker^™ Endobronchial Blocker in the EZ-Multiport^™ Adaptor and then reinsert the bronchoscope. Advance the EZ-Blocker^™ Endobronchial Blocker until the bifurcated ends are in either bronchus. Verify device orientation under visualization by inflating and deflating cuffs.

Before the surgeon breaks the thoracic vacuum, ensure both cuffs of the EZ-Blocker^™ Endobronchial Blocker are deflated and discontinue ventilation until lung collapse is achieved. Inflate the cuff in the bronchus of the lung to be isolated and then resume ventilation.
