The following table describes the features that can be programmed by the operator in the
“Dialysate” screen.
Table 10 – Dialysate Screen Features
Button Function
Concentrate —Touching the Concentrate button opens a subscreen to allow
for the selection of an acid concentrate from a drop down menu. See “Figure
30 – Entering Concentrate Information” on page 67.
Base Na + —This is the prescribed base sodium (Na + ) that will be delivered to
the dialyzer in the Final Dialysate (post proportioning and the reaction of the
acid and bicarbonate concentrates). Selecting this button and using the

or

(
up or down) keys on the data entry keypad, the operator can set the base
sodium content of the dialysate in milliequivalents per liter (mEq/L). The
values of some of the other constituents will change as this parameter is
adjusted (see Table 11 on page 63 for more information).
Bicarbonate —This is the prescribed bicarbonate that will be delivered to the
dialyzer in the Final Dialysate (post proportioning and the reaction of the acid
and bicarbonate concentrates). Selecting this button and using the
 or 
(
up or down) keys on the data entry keypad changes the bicarbonate level in
milliequivalents per liter (mEq/L). The values of some of the other constituents
will change as this parameter is adjusted (see Table 12 on page 64 for more
information).
Acid/Bicarbonate Alert —Touching this button opens a subscreen with
options to notify the user when there is only 20 percent concentrate remaining
in either supply jug. See “Setting the Acid/Bicarbonate Alert” on page 68.
Alarm Position —Selecting this button and using the

or

(
up or down)
keys on the data entry keypad, the operator can shift the conductivity alarm
window, up or down in 0.1 mS/cm increments. The alarm window can be
shifted 0.5 mS/cm above or below the TCD of the selected concentrate type
within the maximum upper limit of 16.0 mS/cm, and the minimum lower limit
of 12.5 mS/cm. For more information, see “Conductivity Limits” on page 69.
Alarm Width —Selecting this button and using the

or

(
up or down) keys
on the data entry keypad, the operator can change the width of the
conductivity alarm window from 0.7 to 1.1 mS/cm width. For more
information, see “Conductivity Limits” on page 69.
SVS Profile —This button, which also appears in the “Home” screen, opens
the “Sodium Variation System (SVS) Profile” subscreen. For more
information, see “Sodium Variation System” on page 80. If the SVS option is
set to ‘No’ in Service Mode, this button will not be displayed.
