Function
Step Profile – Once stable base conductivity has been achieved,
selecting this program will initiate the increase in dialysate sodium.
The dialysate sodium will rise to the program peak sodium level
+
(Na ). The dialysate sodium will remain at this level for the duration
of the program time. When the program time has elapsed, the
dialysate sodium will drop back down to the baseline sodium level.
Linear (Lin) Profile – Once stable base conductivity has been
achieved, selecting this program will initiate the increase in dialysate
sodium. The dialysate sodium will rise to the program starting peak
+
sodium level (Na ). From this point, the dialysate sodium will
decrease toward the baseline sodium level in a straight diagonal
line. This drop will occur over the duration of the program time.
When the program time has elapsed, the dialysate sodium will be at
the baseline sodium level.
Exponential (Exp) Profile – Once the stable base conductivity has
been achieved, selecting this program will initiate the increase in
dialysate sodium. The dialysate sodium will rise to the program's
starting peak sodium level (Na
sodium will decrease over the program time, toward the base
sodium level in a smooth curved line. When the program time has
elapsed, the dialysate sodium will be back at the baseline sodium
level.
None—The level of sodium set in the Base Na
throughout the treatment, with no variations. It does not mean that
no sodium will be used.
The prescribed peak sodium level that will be set at the beginning of
the SVS Profile is accessed here. This value has an allowable range

from base Na to 155 mEq/L. The value displayed corresponds to
the upper tick mark on the vertical axis of the profile graph. This
button will appear grayed out if the None profile is selected.
The prescribed base sodium level of the dialysate can be viewed
here or in the "Dialysate" screen. The Base Na
range of 130 to 155 mEq/L. This value corresponds to the lower tick
mark on the vertical axis of the profile graph.
This button is used to access the program time length in hours and
minutes (0:00 to 9:59) prescribed for SVS operation. Once the SVS
is started, it functions as a count down timer displaying the time
remaining in the SVS program. The end time is represented in the
profile graph by a tick mark on the horizontal axis.
