Abstract (en)

[origin: WO2023062047A1] The invention relates to a method and a device for monitoring blood purification using an extracorporeal blood purification device designed so that blood purification with specified treatment parameters Qb is performed in an extracorporeal blood circuit 9 by means of a blood purification unit 1. A parameter K that is characteristic for the purification performance of the blood purification unit 1 is determined on the basis of the measured concentration of a substance. This parameter K is compared with an expected value K ref . To this end, the computing and/or evaluation unit 25 determines a tolerance range for the expected value, wherein specified actions are triggered by the computing and/or evaluation unit 25 depending on whether the parameter that is characteristic for the purification performance of the blood purification unit is within or outside of the tolerance range for the expected value.
