A:114 AK 98 Dialysis Machine - Isolated ultrafiltration
HCEN12745 Revision 10.2016
Program version 2.xx
6.1 Basic functionality
When performing isolated UF, there is no diffusion. This is because the dialysis fluid in
this phase bypasses the dialyzer, and the machine therefore only performs
ultrafiltration.
Due to the dialysis fluid bypass during isolated UF, the blood cannot maintain its
temperature in the same way as it does during the diffusion phase.
As the UF rate normally is high during the isolated UF phase, high blood flow rate is
recommended, within the limits suitable for the patient, to avoid clotting in the dialyzer
and the blood lines.
The time and UF volume in isolated UF are added to the diffusion phase and increases
the total treatment time and the total ultrafiltration volume .
When the time for the isolated UF phase is finished, the machine will automatically
switch to diffusion phase.
6.2 Handling isolated ultrafiltration
6.2.1 Activate isolated ultrafiltration
When the settings in Section 4.2.9 āSet treatment timeā on pageīA:95 are being
made, set the time and UF volume for the diffusion phase only. Thereafter, make the
settings for the isolated UF phase according to the following instructions.
Procedure
1) Press the Fluid button.
2) Press Isolated UF.
3) Press Isolated UF volume. Set the
ultrafiltration volume for the isolated UF
phase.
4) Press Isolated UF time. Set the time for
the isolated UF phase.
5) Press Activate.
6) Isolated UF will be started when the
Ultrafiltration button is pressed.
Follow the instructions in Section 4.2.13
āStart the treatmentā on pageīA:99.
