Clinical takeaway
Age is the strongest predictor.
When to use
Identify high-risk non-cardiac surgery patients for prevention.
How it works
Seven items (age, SpO₂, recent respiratory infection, anemia, incision site, duration, emergency). < 26 low (≈ 1.6%), 26–44 intermediate (≈ 13.3%), ≥ 45 high (≈ 42.1%).
Key points
- Age is the strongest predictor.
- High scores warrant lung-protective ventilation and respiratory rehab.
- Applies to non-cardiac surgery.

Worked calculation
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.
| Age | 51–80 y (3) |
|---|---|
| Preoperative SpO₂ (room air) | 91–95% (8) |
| Respiratory infection in the last month | No (0) |
| Preoperative anemia (Hb ≤ 10 g/dL) | No (0) |
| Surgical incision site | Upper abdominal (15) |
| Duration of surgery | 2–3 h (16) |
| Emergency procedure | No (0) |
→ARISCAT42
- Band：42 → Intermediate (< 26 low ≈ 1.6%, 26–44 intermediate ≈ 13.3%, ≥ 45 high ≈ 42.1% in-hospital pulmonary complications)
- Action：Intermediate: optimize modifiable factors, lung-protective ventilation, postoperative respiratory rehab and monitoring
- Complications：Postoperative pulmonary complications include respiratory infection, respiratory failure, pleural effusion, atelectasis, pneumothorax, bronchospasm and aspiration pneumonitis
| Age | ≤ 50 y (0) |
|---|---|
| Preoperative SpO₂ (room air) | ≥ 96% (0) |
| Respiratory infection in the last month | No (0) |
| Preoperative anemia (Hb ≤ 10 g/dL) | No (0) |
| Surgical incision site | Peripheral (0) |
| Duration of surgery | < 2 h (0) |
| Emergency procedure | No (0) |
→ARISCAT0
- Band：0 → Low (< 26 low ≈ 1.6%, 26–44 intermediate ≈ 13.3%, ≥ 45 high ≈ 42.1% in-hospital pulmonary complications)
- Action：Low: routine perioperative respiratory care
- Complications：Postoperative pulmonary complications include respiratory infection, respiratory failure, pleural effusion, atelectasis, pneumothorax, bronchospasm and aspiration pneumonitis

FAQ
Frequently asked questions
- What are the limits and cautions when using ARISCAT Score (Postoperative Pulmonary Complications)?
- 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 ARISCAT Score (Postoperative Pulmonary Complications) 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.
- How is ARISCAT Score (Postoperative Pulmonary Complications) calculated in practice? Can you show a worked example?
- Inputs: Age 51–80 y (3), Preoperative SpO₂ (room air) 91–95% (8), Respiratory infection in the last month No (0), Preoperative anemia (Hb ≤ 10 g/dL) No (0), Surgical incision site Upper abdominal (15), Duration of surgery 2–3 h (16), Emergency procedure No (0) → Result: ARISCAT 42（Band: 42 → Intermediate (< 26 low ≈ 1.6%, 26–44 intermediate ≈ 13.3%, ≥ 45 high ≈ 42.1% in-hospital pulmonary complications), Action: Intermediate: optimize modifiable factors, lung-protective ventilation, postoperative respiratory rehab and monitoring, Complications: Postoperative pulmonary complications include respiratory infection, respiratory failure, pleural effusion, atelectasis, pneumothorax, bronchospasm and aspiration pneumonitis） Inputs: Age ≤ 50 y (0), Preoperative SpO₂ (room air) ≥ 96% (0), Respiratory infection in the last month No (0), Preoperative anemia (Hb ≤ 10 g/dL) No (0), Surgical incision site Peripheral (0), Duration of surgery < 2 h (0), Emergency procedure No (0) → Result: ARISCAT 0（Band: 0 → Low (< 26 low ≈ 1.6%, 26–44 intermediate ≈ 13.3%, ≥ 45 high ≈ 42.1% in-hospital pulmonary complications), Action: Low: routine perioperative respiratory care, Complications: Postoperative pulmonary complications include respiratory infection, respiratory failure, pleural effusion, atelectasis, pneumothorax, bronchospasm and aspiration pneumonitis）
