Measurement of the Systemic Pressure
= Pressure at the Entry of the Dialyzer
![Page 3: Mechanical Haemolysis and Systemic Pressure Thomas Ryzlewicz.](https://reader034.fdocuments.in/reader034/viewer/2022042610/570491ca1a28ab14218dda64/html5/thumbnails/3.jpg)
why is the Systemic Pressure Measurement simply necessary?
• to detect a critical Elevation of the mechanical Resistance early in the entire Dialysis System (Dialyzer and Bloodline)
• Condensation of Labor and Experiece had developed unfavourably in nursing

the Additional Mechanical Resistance in the Dialysis System
Resistance in and in front of the Dialyzer
Resistance of the Tubule
Resistance of the Vessel
Additional Resistance, comparable to ET Impedance

how does a HDF-Regime look like?
Qb = 400 cc/min.
Qd = 500 cc/min. in total,
400 cc/min. of it diffusiv
and 100 cc/min. konvektiv
Infusate 6,0 Litres/h.

HDF: Prädilution or Postdilution?
Disadvatage: Reduction of the Conzentration Gradient
Disadvantage: Lengthening of the distances of Diffusion by the packed RBC‘s
Disadvantage: high Sekundary Membrane by Protein
