Abstract
An extracorporeal blood circulation management device having an oxygenator accurately determines oxygen consumption by the target person and oxygen delivery by the oxygenator. Oxygenation-related parameter values in the blood are determined at regular intervals. An in-body passing time (a cycle time for a particular volume of blood to pass from input sensors to output sensors) is determined. Parameter values separated by the in-body passing time are selected as comparison targets to evaluate oxygenation consumption of the target person. An oxygenator unit passing time is determined. Parameter values separated by the oxygenator unit passing time are selected as comparison targets to evaluate oxygenation delivery of the oxygenation unit.
