The post-filter calcium concentration indicates the efficacy of the
regional citrate anticoagulation and can be used as a control parameter.
Adding substituate upstream of the haemofilter.
The substituate is the replacement fluid used in haemofiltration.
Systemic calcium concentration is the concentration of systemic ionised
calcium. This measured value is used to verify and control calcium
substitution.
The ultrafiltration volume is the fluid volume removed from the blood by
filtration which is required for the patient to lose weight. (The removal
rate is indicated in ml/h.)
The venous section is the section of the extracorporeal circuit from the
dialyser outlet port to the patient.
The venous return pressure is the pressure at a defined site in the
venous section, e.g., in the bubble catcher.
