20220016325 · 2022-01-20 ·

A monitoring device operates to monitor regional citrate anticoagulation (RCA) in a blood treatment system which is configured to administrate citrate to an extracorporeal blood circuit (10) upstream of a dialyzer (11) during a treatment session. At consecutive time steps during the treatment session, the monitoring device obtains a current measurement value of systemic ionized calcium (iCa.sub.SYS) or systemic total calcium (Ca.sub.SYS), operates a predefined algorithm on the current measurement value to generate a current computation value that represents ionized calcium (iCa.sub.2, iCa.sub.3) in blood at a selected location (loc2, loc3) downstream or upstream of the dialyzer (11) in the extracorporeal blood circuit (10), and presents and/or evaluates the current computation value for assessment of the regional citrate anticoagulation. The need for conventional blood sampling and blood analysis upstream and/or downstream of the dialyzer, e.g. during CRRT, is thereby reduced significantly.
