HEMODIALYSIS
HD
The transport of uremic wastes by diffusion, i.e. the process in which
of particles move across a semipermeable membrane from the area
of higher concentration (blood) to the area of lower concentration
(dialysate).

Hemofiltration HF
Filtrate
Substituate
Removal of uremic wastes by convective transport. The driving force is provided
by the transmembrane pressure present at the hemofilter.
Due to the filtration of large volumes during hemofiltration, simultaneous reconstitution of blood with appropriate amounts of physiologic replacements solution
is required.

Hemodiafiltration HDF
Filtrate
Substituate
Hemodiafiltration is a combination of hemodialysis and hemofiltration to take advantage of the benefits of hemodialysis - high clearance of small-molecular substances
and hemofiltration - good clearance with middle-molecular substances.

1. Closing of the BC valves with the current increase pulse
2. Waiting for the floater to reach “up”-position
3. V41-control disabled. V26, V43, V87 & BC fresh fluid valves open,
degassing pump delivers fluid with reduced speed from the heater block,
until the lower switch point of the floater is reached.

4. 1 BC cycle → level in 66 c: 30ml below lower switch point
5. V26, V87 & BC fresh fluid valves open, V43 closed,
degassing pump off, UF-Pump: 4 strokes
→ Level: 34ml below lower switch point
6. V84, V86 open, UF-Pump: 50 strokes = 50ml disinfectant
(Dilution 1:25), the conductivity is monitored by the sensors 115:
If there is no conductivity detected after 24 strokes, the process
is stopped: alpha display “DISINFECTANT EMPTY ?”
After 50 strokes of the UF-Pump the floater must be in “up” position.

Prior Aspiration of Disinfectant
The given values are based on a standard machine. For machines
including Diasafe or On-Line-HDF the vol. of disinfectant are increased!

4. V26, V87 & BC fresh fluid valves open, V43 closed,
degassing pump off, UF-Pump: 23 strokes = 23ml
5. After the disinfectant is connected the aspiration is done by use of
the acid pump.
32 strokes of acid pump = 37ml disinfectant (Dilution 1:34)
6. After aspiration the floater must be in “up”-position.

2.
Check the Closed System for tightness:
2.1
With Negative Pressure
- Connect an external dialysate pressure gauge
- Eliminate air from the hydraulic unit by selecting
menu point CALIBRATION / UF-Pump (Ver 1):
machine performs FILL PROGRAM (flow must be on)
- Open V24, V24b, V30, V87
May 2001
- Create a dialysate pressure of app. -500mmHg by
the ASP
- Observe the dialysate pressure
to be stable for 3 min.
- Max. pressure change: +40mmHg
- If pressure stable, the closed system is tight
May 2001
2.2
With Positive Pressure
- Connect hydraulic pressure gauge to measure
point C (Flow Pump outlet)
menu point CALIBRATION / UF-Pump (Ver 1):
machine performs FILL PROGRAM (flow must be on)
- Enable float switch
May 2001
- Open V35, V31, V24, V24b, V87
- Run degassing pump
- Close V35, V31
- If pressure on the hydraulic pressure gauge is stable,
the closed system is tight
May 2001
- Check heater exchanger, V86, V87
- Close V87
- Open V43
- Pressure stable ?
May 2001
3.
Check Balancing Chamber Valves for tightness:
menu point CALIBRATION / UF-Pump (Ver 1)
3.1
Check the fresh dialysate valves:
- Open float switch
- Open V24, V24b, V30, V87
May 2001
- Run degassing pump
- Create a dislysate pressure of app. -500mmHg by
the ASP
- Test of V35:
- Open V31
- Observe the dialysate pressure to be stable for 3 min.
- Max. pressure change: +40mmHg
- If pressure is stable, V35 is tight
- Close V31
May 2001
- Test of V37:
- Open V33 ...
- Test of V31:
- Open V35 ...
- Test of V33:
- Open V37 ...
May 2001
3.2
Check the spent dialysate valves:
- Open V24, V24b, V30, V87
- Run flow pump
- Open V43 to reduce dialysate pressure
- Close V43
May 2001
- Test of V36:
- Open V32
-
Observe the dialysate pressure to be stable for 3 min.
Max. pressure change: -40mmHg
If pressure is stable, V36 is tight
- Close V32
May 2001
- Test of V38:
- Open V34 …
- Test of V32:
- Open V36 …
