Provided are an information processing apparatus and an information processing program that enable easy understanding of blood pressure fluctuation caused by sleep apnea syndrome for an individual person. An information processing apparatus according to the present invention has: an information acquisition unit that acquires SPO2 measurement data and blood pressure value measurement data which are taken through continuous measurement from a specific person to be tested； a blood pressure fluctuation detection unit that detects blood pressure fluctuation equal to or higher than a reference value, from the blood pressure value measurement data taken through continuous measurement and acquired by the information acquisition unit； an association determination unit that determines the degree of likelihood of blood pressure fluctuation caused by sleep apnea syndrome, on the basis of association between the blood pressure fluctuation which is equal to or higher than the reference value, and which is detected by the blood pressure fluctuation detection unit, and the measurement data of the SPO2； and a display control unit that causes a display device to display the degree of likelihood of blood pressure fluctuation, which is caused by sleep apnea syndrome, determined by the association determination unit.La présente invention concerne un appareil de traitement d'informations et un programme de traitement d'informations qui permettent une compréhension aisée d'une fluctuation de pression artérielle causée par le syndrome d'apnée du sommeil pour une personne individuelle. Un appareil de traitement d'informations selon la présente invention comporte : une unité d'acquisition d'informations qui acquiert des données de mesure de SPO2 et des données de mesure de valeur de pression artérielle qui sont acquises par mesure continue à partir d'une personne spécifique à tester； une unité de détection de fluctuation de pression artérielle qui détecte une fluctuation de pression artériel
