Single lumen endobronchial tube

Photograph of the Phycon single-lumen endotracheal/endobronchial tube, above a standard endotracheal tube (Fuji Systems, Tokyo, Japan) (A). To the right, a photograph of the distal end of the tube with a 12 cc syringe for comparison (B). This long (36 cm) single-lumen tube has a short cuff and does not have a Murphy eye. This increases the margin of safety when these tubes are positioned in the mainstem bronchus for one-lung ventilation. The cuff can be inflated to function as an endotracheal tube or advanced over a fiberoptic bronchoscope into the mainstem bronchus as needed.
