(A) Double lumen endobronchial tube is inserted into the mouth in the midline and then shifted to the right side of the mouth. (B) A video laryngoscope is inserted. (C) The bronchial lumen and bronchial cuff are advanced into the glottis. (D) Once below the vocal cords the stylet is removed from the double lumen endobronchial tube. (E) A fiberoptic scope is introduced into the bronchial lumen and the trachea is imaged. (F) The fiberoptic bronchoscope is advanced into the left mainstem bronchus. (G) The double lumen endobronchial tube is advanced over the fiberoptic scope and the bronchial lumen and cuff are advanced into the left mainstem bronchus. (H) The fiberoptic scope is inserted into the tracheal lumen and final adjustment to the depth of the double lumen endobronchial tube is performed so that a rim of the bronchial cuff can be seen at the carina
