The Smiths Medical 100/166/070 is a Soft Seal Endotracheal Tube designed for both oral and nasal use. It comes in a size of 7mm and is sold in boxes of 10. This tube features a one-way valve for efficient and easy inflation and deflation of the cuff. The large pilot balloon clearly indicates when the cuff is inflated. It also includes an intubation depth marker located 3cm proximal to the cuff, which assists in accurately placing the tip within the trachea. The large cuff diameter ensures an effective seal and reduces movement relative to the trachea during ventilation. This tube is designed to provide maximum patient comfort and safety.
