Methodology · worked example, guidelines & full notes
Any single domain scoring 3 is high risk regardless of total.
When to use
Early identification of deteriorating children to trigger escalation and rapid response.
How it works
Behaviour + cardiovascular + respiratory (each 0–3) + continuous nebs/CPAP and post-op vomiting (+2 each). Total ≥ 3 escalate, ≥ 5 consider RRT, any single domain = 3 high risk.
Key points
- Any single domain scoring 3 is high risk regardless of total.
- Carer/nurse concern should be able to escalate beyond the score.
- Compare HR/RR against age-specific ranges.

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.
| Behaviour | Sleeping (1) |
|---|---|
| Cardiovascular | Pale or CRT 3 s (1) |
| Respiratory | > normal +10 or accessory muscles or FiO₂ ≥ 30%/3 L (1) |
| Continuous nebulizer (q20min bronchodilator) or CPAP | No (0) |
| Persistent post-operative vomiting | No (0) |
→PEWS3
- Components：Behaviour 1 + cardiovascular 1 + respiratory 1 = 3 (core 0–9, with add-ons 0–13)
- Action：Escalate monitoring: inform the responsible clinician, increase observation frequency (e.g. hourly), reassess the trend
- Escalation：Total ≥ 3 → escalate monitoring; ≥ 5 → consider RRT; any single domain = 3 → high risk. Compare HR/RR with age-specific ranges
| Behaviour | Playing / appropriate (0) |
|---|---|
| Cardiovascular | Pink or CRT 1–2 s (0) |
| Respiratory | Normal (0) |
| Continuous nebulizer (q20min bronchodilator) or CPAP | No (0) |
| Persistent post-operative vomiting | No (0) |
→PEWS0
- Components：Behaviour 0 + cardiovascular 0 + respiratory 0 = 0 (core 0–9, with add-ons 0–13)
- Action：Routine monitoring with periodic reassessment; carer/nurse concern can escalate regardless of score
- Escalation：Total ≥ 3 → escalate monitoring; ≥ 5 → consider RRT; any single domain = 3 → high risk. Compare HR/RR with age-specific ranges

FAQ
Frequently asked questions
- What are the limits and cautions when using Pediatric Early Warning Score (PEWS)?
- 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 Pediatric Early Warning Score (PEWS) 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 Pediatric Early Warning Score (PEWS) calculated in practice? Can you show a worked example?
- Inputs: Behaviour Sleeping (1), Cardiovascular Pale or CRT 3 s (1), Respiratory > normal +10 or accessory muscles or FiO₂ ≥ 30%/3 L (1), Continuous nebulizer (q20min bronchodilator) or CPAP No (0), Persistent post-operative vomiting No (0) → Result: PEWS 3（Components: Behaviour 1 + cardiovascular 1 + respiratory 1 = 3 (core 0–9, with add-ons 0–13), Action: Escalate monitoring: inform the responsible clinician, increase observation frequency (e.g. hourly), reassess the trend, Escalation: Total ≥ 3 → escalate monitoring; ≥ 5 → consider RRT; any single domain = 3 → high risk.
