Schematic diagram portraying use of embolectomy catheter (EC) for achieving lung isolation in pediatric patients. A Appropriately sized EC bent 30° at the tip is passed through glottis into trachea under direct vision by laryngoscopy. B Undersized cuffed ETT is then placed into the trachea, anterior to EC, until its black mark is below the glottis; its cuff is inflated with air and bilateral air entry confirmed. C A lubricated pediatric FOB is advanced through ETT beyond its tip to visualize the trachea, carina, and the tip of EC. D The cuff of ETT is deflated and the EC is maneuvered into the desired bronchus by applying torque its extra-oral part. Its guide wire is removed, and the cuff inflated under vision with air. Inflating volume is noted and thereafter ETT cuff is inflated
