Formula and scoring

Revised Baux = age (years) + %TBSA + 17 × inhalation injury (1 = yes, 0 = no).

Exam and ward pearls

  • Inhalation injury is worth 17 points — the same as 17 years of age or 17% extra burn.

When not to rely on it

  • The score itself is not a probability; Osler 2010 gives a logistic conversion. Use it to grade severity and to compare units, not to withdraw care in an individual.
