1 Mechanical Haemolysis and Systemic Pressure Thomas Ryzlewicz

2 Measurement of the Systemic Pressure = Pressure at the Entry of the Dialyzer

3 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

4 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

5 the Additional Mechanical Resistance in the Dialysis System Resistance in and in front of the Dialyzer Resistance of the Tubule Resistance of the Vessel here no Alarm Monitoring(!) Alarm Monitoring by venous Pressure

6 ... and now the Resistance in the Dialyzer increases... Resistance in and in front of the Dialyzer Resistance of the Tubule Resistance of the Vessel here no Alarm Monitoring(!) Alarm Monitoring by venous Pressure

7 ... and now the Resistance in the Dialyzer increases... Resistance in and in front of the Dialyzer Resistance of the Tubule Resistance of the Vessel here no Alarm Monitoring(!) Alarm Monitoring by venous Pressure HAEMOLYSIS

8 ... und wenn jetzt der Widerstand im Dialysator steigt... Widerstand im und vor dem Dialysator Kanülen-WiderstandGefäß-Widerstand hier Alarmüberwachunghier keine Alarm- überwachung (!) HAEMOLYSIS

9 ... und wenn jetzt der Widerstand im Dialysator steigt... Widerstand im und vor dem Dialysator Kanülen-WiderstandGefäß-Widerstand hier Alarmüberwachunghier keine Alarm- überwachung (!) HÄMOLYSE !

20 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.

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

22 HDF: Prädilution or Postdilution? Prä- Dilution Post- Dilution Lengthening of the way of Diffusion Sekundary Membrane Reduction of the Conzentration Gradient
