Abstract:
1. A method for determining a treatment parameter on a haemofiltration device having a blood cleansing element divided into first and second chambers by a semipermeable membrane, said first chamber forming part of an ultrafiltrate outlet system and said second chamber forming part of an extracorporeal blood circulation system, the device also having a substitution-fluid addition system with which substitution fluid can be added to the extracorporeal blood circulation system, the method comprising the steps of: determining a fluid flow Qo led away from the first chamber; determining a first physical-chemical characteristic Cs changing the physical-chemical characteristic Cs in the substitution fluid; determining a second physical-chemical characteristic Cs determining a treatment parameter from the determined values of the fluid flow Qo led away, the physical-chemical characteristics Cs
