Tracheostomy Tube

Tracheostomy tube

Definition
A tracheostomy (trach) tube is a curved tube that is inserted into a tracheostomy stoma. All tracheostomy tubes have similar parts including:
  • Tube or cannula: part that goes in the stoma
  • Adaptor : universal size to allow connection of respiratory equipment
  • Flange : place to connect the ties
  • Obturator : guide used during trach tube change
Trach tubes come in different sizes and types.
  • Internal diameter ranges from 3.0 mm to 6.5 mm for pediatric single cannula tubes.
  • The length of the tube increases with the increasing tube size. Neonatal trach tubes are shorter than pediatric trach tubes.
  • Curvature of the trach tube varies by brand and size. The goal is to avoid touching the posterior wall of the trachea.
  • Adult sized tubes may have inner cannulas.
  • Trach tubes may have a cuff.

Tube selection is dependent on size of the airway. The type of trach tube used is dependent on the child's needs.
