[Problem] To provide an extracorporeal circulation management device, an extracorporeal circulation device, and an extracorporeal circulation management program that make it possible for a technician or the like to easily ascertain the cause of a circulation failure in extracorporeal circulation. [Solution] An extracorporeal circulation management device 10 displays, on a display unit 16, an estimated flow rate estimated in advance serving as an estimated value of the flow rate of blood flowing inside a circulation circuit 1R, and an actual flow rate measured by a flow rate measurement unit 24 serving as an actual measured value of the flow rate of the blood flowing inside the circulation circuit 1R； and also displays, on the display unit 16, a standard pressure calculated on the basis of the estimated flow rate by referencing standard information which is stored in a storage unit and which expresses the relationship between the flow rate of the blood and pressure loss occurring in devices 2, 5, 6 installed on the circulation circuit 1R, and an actual pressure which serves as an actual measured value of the pressure of the blood flowing inside the circulation circuit 1R and which relates to the devices 2, 5, 6, the actual pressure being calculated on the basis of the actual flow rate and an actual pressure measured by pressure measurement units 21, 22, 23.La présente invention concerne un dispositif de gestion de circulation extracorporelle, un dispositif de circulation extracorporelle et un programme de gestion de circulation extracorporelle qui permettent à un technicien ou un professionnel d'évaluer facilement la cause d'une défaillance de circulation dans une circulation extracorporelle. Un dispositif de gestion de circulation extracorporelle 10 affiche, sur une unité d'affichage 16, un débit estimé, estimé à l'avance, servant de valeur estimée du débit de sang circulant à l'intérieur d'un circuit de circulation 1R, et un débit réel mesuré par une unité de mesur
