Swivel
A swivel is often attached to the end of the tracheostomy tube. Some unique
characteristics of children make the swivel particularly useful. First, children have

movement in the ventilator-assisted child, so traction is not placed on the
ventilator tubing or on the tracheostomy tube. Second, the short neck and bulky
soft tissues of young children can obstruct the tracheostomy tube opening. The
swivel provides additional length, so the tube opening extends beyond the soft
tissues of the neck.
Heat–Moisture Exchanger
Air inspired directly into the trachea through a tracheostomy tube bypasses the
important warming and humidification mechanisms provided by the natural upper
airway. Therefore, a humidification system is an important component of the
equipment used in a patient with a tracheostomy. A home ventilator setup
