Some Types of Tracheostomy Tubes

Double-Lumen Tube
The double-lumen tube has the following parts:

Outer cannula—fits into the stoma and keeps the airway open. The face plate
indicates the size and type of tube and has small holes on both sides for
securing the tube with tracheostomy ties or another device.
Inner cannula—fits snugly into the outer cannula and locks into place. It
provides the universal adaptor for use with the ventilator and other
respiratory therapy equipment. Some may be removed, cleaned, and reused;
others are disposable.
Obturator—a stylet with a smooth end used to facilitate the direction of the tube
when inserting or changing a tracheostomy tube. The obturator is removed
immediately after tube placement; an obturator is always kept with the client
and at the bedside in case of accidental decannulation.
Cuff—when inflated, seals the airway. The cuffed tube is used for mechanical
ventilation, preventing aspiration of oral or gastric secretions, or for the client
receiving a tube feeding to prevent aspiration. A pilot balloon attached to the
outside of the tube indicates the presence or absence of air in the cuff.
