A tracheostomy tube assembly which includes a short, curved outer cannula affixed to a neck plate with strap, and a removable inner cannula having an affixed inflatable endotracheal cuff. When in use, the endotracheal cuff of the inner cannula is positioned beyond the terminal end of the outer cannula within the trachea. In a slightly varied embodiment of the invention, an accessory oxygen attachement is included for attachment to the outer cannula with the inner cannula and endotracheal cuff removed. The oxygen attachment is sized for releasable attachment over the outer exposed open end of the short outer cannula. The oxygen attachment is comprised a solid core plug having a narrow flexible air line positioned therethrough. The flexible air line is structured for attachment to an oxygen hose from an oxygen supply.
