When to use

Japanese Respiratory Society modification of CURB-65; community-acquired pneumonia severity (0–5).

How it works

Age (men ≥70 / women ≥75), dehydration (BUN ≥21 mg/dL), respiration (SpO₂ ≤90% / PaO₂ ≤60 mmHg), disorientation, SBP ≤90 mmHg; +1 each.

Key points

  • Age (men ≥70 / women ≥75), dehydration (BUN ≥21 mg/dL), respiration (SpO₂ ≤90% / PaO₂ ≤60 mmHg), disorientation, SBP ≤90 mmHg; +1 each.
  • 0 mild · 1–2 moderate · 3 severe · 4–5 very severe.

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 (male ≥ 70 / female ≥ 75)No
Dehydration (BUN ≥ 21 mg/dL or clinical dehydration)No
Respiratory failure (SpO2 ≤ 90% or PaO2 ≤ 60 mmHg)No
Orientation disturbance (confusion)No
Systolic BP ≤ 90 mmHgNo
