Features of Tracheostomy Tubes
Tracheostomy tubes have different features depending on their intended
use. There are a large variety of tubes available which provide some or all
of these features.
Introducers
All tracheostomy tubes should be inserted using an introducer to prevent
damaging the trachea during insertion of the tube. Once the tracheostomy
tube has been inserted the introducer should be disposed of.
Cuffs
Some tracheostomy tubes have a cuff which, when inflated, provides an
airtight seal which facilitates artificial ventilation.
Inner tubes
Tracheostomy tubes with inner tubes consist of an outer tube, which
remains insitu, through which a smaller, inner tube is inserted. The inner
tube has an extension at its upper aspect that can be connected to other
equipment. It can be removed for cleaning and when weaning the patient.
A replacement non-fenestrated inner tube must be kept at the patients
bedside at all times.
