The Endotracheal Tube Uncuffed (Plain) of GSTC is made up of medical grade PVC material which is biocompatible, non-toxic and pyrogen free. The tube has a bevelled tip that allows for easy, atraumatic passage into the trachea. Tube design is kink resistant so air flows consistently during ventilation. The tube also has a radiopaque line that makes it easy to find the position of the tube with an X-ray. The sizes of the tubes range from 2 mm to 11 mm, with an interval of 0.5 mm. Each tube is tamper-proof packed under sterile conditions.
