Abstract
A method for determining a treatment parameter on a haemofiltration device, as well as a haemofiltration device for applying the method, based on the recognition that a determination method known from haemodialysis can, with little modification, be transferred to haemofiltration. To this effect a physical-chemical characteristic of the substitution fluid and of the fluid which is removed from the haemofilter by way of an ultrafiltrate outlet pipe, is determined. Furthermore, this characteristic is acquired before, after or during a change of this characteristic in the substitution fluid, and is evaluated. As a result, the ion dialysance and thus the urea clearance of a haemofiltration device, which can also be operated as a haemodiafiltration device, can be determined.
