Tracheal tube

A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent airway and to ensure the adequate exchange of oxygen and carbon dioxide.

Many different types of tracheal tubes are available, suited for different specific applications:

• An endotracheal tube is a specific type of tracheal tube that is nearly always inserted through the mouth (orotracheal) or nose (nasotracheal).
• A tracheostomy tube is another type of tracheal tube; this 50–75-millimetre-long (2.0–3.0 in) curved metal or plastic tube may be inserted into a tracheostomy stoma (following a tracheotomy) to maintain a patent lumen.
• A tracheal button is a rigid plastic cannula about 25 millimetres (0.98 in) in length that can be placed into the tracheostomy after removal of a tracheostomy tube to maintain patency of the lumen.
