Sequential Dialysis - Fresenius Medical Care 2008T Operator's Manual

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, select the UF Time button.

To change the UF goal, select 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.

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 'SEQ' (a
special flow rate of 0 ml/min), and only ultrafiltration occurs. The Temperature button in
the "Home" screen displays 'N/A'.
Note: Setting and confirming the Dialysate Flow to '0' will turn it OFF instead of running
sequential dialysis. After five minutes of pure ultrafiltration, an alarm sounds and the
warning message, "5 MINUTES FLOW OFF," appears in the Status Box. The operator has
the option of continuing pure ultrafiltration or starting dialysis. This alarm occurs only
once.
