PROBLEM TO BE SOLVED: To detect a blood pressure serge from time series data of a blood pressure value.SOLUTION: A blood pressure data processing device comprises: an acquisition part which acquires time series data of a blood pressure value； a calculation part which sets one or more peak detection sections to the time series data and calculates a feature amount based on one of a systolic blood pressure, a diastolic blood pressure, and a pulse pressure in each peak detection section； and an identification part which identifies at least one first peak from the feature amount in each peak detection section.SELECTED DRAWING: Figure 1【課題】血圧値の時系列データから血圧サージを検出すること【解決手段】 血圧値の時系列データを取得する取得部と、前記時系列データに１つ以上のピーク検出区間を設定し、当該ピーク検出区間ごとの収縮期血圧、拡張期血圧、脈圧のいずれかに基づく特徴量を算出する算出部と、前記ピーク検出区間ごとの特徴量から少なくとも１つの第１ピークを特定する特定部と、を備える。【選択図】 図１
