Instructions for use
Choosing the appropriate inner and outer diameter sizes of the tracheostomy tube are important when recommending the initial tracheostomy tube size or tracheostomy tube changes.
A tracheostomy tube from one manufacturer may not correspond to the same size from a different manufacturer as they may have different internal/external diameters or length. Different manufacturers follow different sizing guidelines: some tracheostomy tubes utilise the Jackson sizing system, while other tubes use the ISO method.
The appropriate dimensions are listed on the flange of the tracheostomy tube.
ISO requires that tracheostomy tubes are sized according to the narrowest part of the inner diameter which includes the inner cannula. The outer cannula is measured as the largest diameter of the outer cannula.
Size | Inner Ø | Outer Ø | length | Use for |
4 | 5.0 mm | 9.4 mm | 60 - 65 mm | Child |
6 | 6.4 mm | 10.8 mm | 70 - 76 mm | Adolescent Adult woman |
8 | 7.6 mm | 12.2 mm | 70 - 82 mm | Adult man |
