Chapter 3—Setting Treatment Parameters
Note: The "None" profile performs ultrafiltration at a constant rate. It does not mean that no
ultrafiltration will occur.
The maximum UF rate is displayed for the selected profile, UF Goal, and UF Time. If the
maximum UF Rate is too high (beyond the configuration of the machine), a message appears
in the Dialogue Box located in the upper, right corner of the screen. The operator has the
option of increasing the UF Time, reducing the UF Goal, or selecting another profile.
To change the profile, select the corresponding profile button.
To change the time, touch the UF Time button.
To change the UF goal, touch the UF Goal button. The maximum ultrafiltration rate, based
on the UF Goal, Time & Profile, will be calculated and displayed in the Maximum UF-Rate
display.
When all ultrafiltration parameters are satisfactory, press CONFIRM to save the changes,
then exit from the "UF Profile" screen. The machine will apply the new UF profile to the
remaining UF time in twelve equal segments.
Note: With software versions prior to 3.12, if any UF parameter is changed after a UF
profile program has started, a new UF profile is started from the beginning of the indicated
Profile for the displayed UF time. Beginning with version 3.12, the UF goal may be
changed during a profile. The UF rates will be automatically recalculated to achieve the
desired UF Goal. Changing the UF Profile or UF time will cause a new profile to begin.
Sequential Dialysis
Sequential dialysis refers to a two-stage treatment in which one of the stages consists solely
of ultrafiltration without dialysate flow (no diffusion). This stage of the treatment is also
referred to as "pure UF," or "no-flow dialysis," and is often prescribed for patients suffering
from excessive fluid retention. Pure UF is usually performed at the beginning of a standard
dialysis treatment, although it can also be administered during treatment. The operator can
start or stop the pure UF option at any time. In pure UF, Dialysate Flow is set to 0 ml/min
and only ultrafiltration occurs. The Temperature button in the "Home" screen displays N/A.
