When to use
Identify patients who should undergo sleep testing, including pre-operatively.
How it works
Eight yes/no items (Snoring, Tiredness, Observed apnoea, Pressure, BMI > 35, Age > 50, Neck > 40 cm, male sex). 0–2 low, 3–4 intermediate, 5–8 high.
Key points
- ≥ 5 indicates high probability of moderate–severe OSA.
- A screen, not a diagnosis — refer for sleep testing.
- Relevant to peri-operative risk assessment.

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.
| Snoring loudly | No |
|---|---|
| Tiredness/daytime sleepiness | No |
| Observed apnoea | No |
| High blood pressure | No |
| BMI > 35 kg/m² | No |
| Age > 50 | No |
| Neck circumference > 40 cm | No |
| Male sex | No |
→STOP-BANG0/8
- Risk：Low risk of OSA
- Note：≥ 5 (or STOP ≥ 2 plus male/BMI/neck) indicates high probability of moderate–severe OSA.
