The appropriate tracheostomy tube size depends on the individual's anatomy, particularly their sex.
As a general rule, consider the following:
- Adult Females: Most adult females can accommodate a tube with an outer diameter of 10mm.
- Adult Males: An outer diameter of 11mm is typically suitable for most adult males.
It's important to choose a tube that is not wider than necessary to minimize trauma to the tracheal wall and prevent long-term complications.
| Sex | Typical Outer Diameter |
|---|---|
| Females | 10mm |
| Males | 11mm |
