Shock threshold SBP: 5th centile ≈ 70 + (2 × age in years) mmHg for 0–10y; <90 mmHg at >10y.SpO2 : ≥95% on air normal; 92–94% concerning; <92% serious; any supplemental O2 raises the bar.Temperature: fever ≥38.0°C (red flag at any age <3 months per NICE CG160). Hypothermia <36.0°C.CRT: <2s normal; 2–3s borderline; ≥3s delayed / concerning.AVPU: A normal; V = concerning; P/U = emergency (GCS equivalent ≤8).
