The endotracheal tube provides an alternative pathway for gas flow in case of occlusion. It increases strength & flexibility, and provides reliable control of cuff inflation and pressure. The clear 15mm connector enables connection to standard anaesthetic and ventilation breathing system equipment for ease of use. The tube minimises trauma to the trachea with a low pressure seal against the tracheal wall, protecting the patient's airway. Size 4 to 10. Box of 20.
