Abstract

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 SYS ) or systemic total calcium (Ca SYS ), operates a predefined algorithm on the current measurement value to generate a current computation value that represents ionized calcium (iCa 2 , iCa 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.

Description

technical field [0001] The present invention relates to regional citrate anticoagulation (RCA) during blood treatment, and more particularly to a system for performance monitoring during blood treatment (e.g., continuous or semi-continuous renal replacement therapy) involving RCA. technology. Background technique [0002] Continuous or semi-continuous renal replacement therapy has become an accepted treatment option for supporting critically ill patients with acute kidney injury. Continuous renal replacement therapy (CRRT) is typically a 24-hour treatment, while semi-continuous therapy can be administered for 6-12 hours per day or longer durations. There are many different forms or "modalities" of continuous or semi-continuous renal replacement therapy, including but not limited to CVVH (continuous veno-venous hemofiltration), CVVHD (continuous veno-venous hemodialysis), CVVHDF (continuous veno-venous hemodiafiltration Hemofiltration), SLEF (slow extended hemofiltration), ...
