Methodology · worked example, guidelines & full notes
AIS predicts mortality imperfectly; the revised Baux score (age + %TBSA + 17×inhalation) predicts death better, so combine the grade with TBSA and oxygenation. (original synthesis · not guideline verbatim)
When to use
Use after smoke/inhalation exposure to grade injury from bronchoscopy and anticipate airway compromise — particularly upper-airway edema, which can progress within 24 h.
How it works
Bronchoscopic appearance → AIS 0 (none) to 4 (massive, mucosal sloughing/necrosis). Grades 2–4 carry worse survival and prompt escalating airway clearance and lung-protective ventilation.
Key points
- AIS predicts mortality imperfectly; the revised Baux score (age + %TBSA + 17×inhalation) predicts death better, so combine the grade with TBSA and oxygenation. (original synthesis · not guideline verbatim)
- Facial/oropharyngeal burns, hoarseness, stridor, carbonaceous sputum, or a closed-space fire warrant early airway evaluation and a low threshold to intubate.
- Severe grades need aggressive bronchial hygiene (clearing eschar/pseudomembrane) and lung-protective ventilation.

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Bronchoscopic appearance | Grade 2 (moderate): moderate erythema, carbonaceous deposits, bronchorrhea or bronchial obstruction |
|---|
→Inhalation injury AISGrade 2
- Grade：Grade 2 (moderate). Grades 2–4 have worse survival than 0–1
- Management direction：Moderate: bronchial hygiene, nebulized bronchodilators, chest physiotherapy, close monitoring of airway edema and oxygenation
- Airway warning：Facial/oropharyngeal burns, hoarseness, stridor, carbonaceous sputum, closed-space fire history → beware airway obstruction; edema can progress within 24 h of injury, so evaluate/intubate early
| Bronchoscopic appearance | Grade 0 (none): no carbonaceous deposits/erythema/edema/bronchorrhea/obstruction |
|---|
→Inhalation injury AISGrade 0
- Grade：Grade 0 (no injury). Grades 2–4 have worse survival than 0–1
- Management direction：Mild/none: monitor airway and oxygenation, supportive care
- Airway warning：Facial/oropharyngeal burns, hoarseness, stridor, carbonaceous sputum, closed-space fire history → beware airway obstruction; edema can progress within 24 h of injury, so evaluate/intubate early

FAQ
Frequently asked questions
- What are the limits and cautions when using Inhalation Injury Grading (Bronchoscopic AIS)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does Inhalation Injury Grading (Bronchoscopic AIS) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
