⚠️ NEWS2 Score (National Early Warning Score 2)
Calculate the National Early Warning Score 2 (NEWS2) to detect acute clinical deterioration.
NEWS2 Score (National Early Warning Score 2)
Respiratory rate (/min)
SpO₂ (scale 1) (%)
On supplemental O₂
Systolic BP (mmHg)
Heart rate (bpm)
Temperature (°C)
Consciousness (ACVPU)
When to use
Track-and-trigger monitoring of acutely ill adults (non-pregnant).
How it works
Aggregate points from respiratory rate, SpO₂ (scale 1), air/O₂, systolic BP, pulse, consciousness (ACVPU) and temperature. Bands: 0 routine, 1–4 low, 5–6 (or any single 3) medium, ≥ 7 high.
Key points
- A single parameter scoring 3 triggers urgent review.
- Use SpO₂ Scale 2 for target 88–92% (hypercapnic risk).
- Escalation thresholds follow local policy.
