計算方法と公式
Definition checklist + low-risk bundle (age, gestation, first event, no CPR, Hx/exam).
Confirm definition first; only then classify low- vs higher-risk.
計算例（数値代入）
以下の数値は本ツールの入力欄に定義された例示値であり、本ページの数式でサーバー側で実際に計算したものです。計算過程を素早く確認できます。代入方法の例示のみで、臨床上の助言ではなく、実在する症例でもありません。
| Infant age < 1 year | No |
|---|---|
| Event was brief (<1 minute; typically <20–30 s) | No |
| Now resolved / back to baseline | No |
| ≥1 feature: cyanosis or pallor; absent/decreased/irregular breathing; marked change in tone; altered responsiveness | No |
| Unexplained after appropriate history and physical (no explanation such as GER reflux witnessed, nasal obstruction, etc.) | Explained / alternative diagnosis |
| Low-risk age: >60 days | No (≤60 d) |
| Low-risk gestation: ≥32 weeks AND postconceptional age ≥45 weeks | No |
| Low-risk: first BRUE (no prior BRUE / no cluster) | No — prior or cluster |
| Low-risk: no CPR by trained medical provider | CPR was given by trained provider |
| Low-risk: no concerning historical features (e.g. unexplained death of sibling, possible child abuse, family history concerning for arrhythmia) | Concerning history present |
| Low-risk: no concerning physical exam findings | Concerning exam |

結果の判読と層別
Low-risk may allow limited ED evaluation; higher-risk needs broader workup/admission.
ガイドライン要点（独自整理）
