Allow Slow Flow

The Allow Slow Flow option allows the machine to run dialysate flows of 100 or 200 ml/min.
This feature is activated in Service Mode and requires a temperature calibration. Please refer
to the 2008T Hemodialysis System Calibration Procedures manual (P/N 508032).
SVS
The SVS (Sodium Variation System) feature may be enabled or disabled (software version
2.34 or later).
Heparin Dwell
The Heparin Dwell option displays the Heparin Dwell button on the "Heparin" screen. The
button acts as a five minute timer; after a manual heparin bolus is administered and the
operator selects and confirms the Heparin Dwell button, causing the yellow Status Light to
flash for five minutes while the heparin is dwelling.
Kt/V Graph Tolerance
Either a 0% or a 15% tolerance from the target Kt/V is selectable in Service Mode. If 15% is
selected and the projected Kt/V is less than 85% of the target, the operator will be alerted. If
0% is selected and the projected Kt/V is less than 100% of the target, the operator will be
alerted.
Kt/V Default
The default Kt/V (target or minimum value) is selectable in the Service Mode.
Language
The operating screens may be setup so that they are in either French (Canada), Spanish
(Mexico) or English (USA). Service Mode is always in English.
Arterial and Venous Pressure Limits
The width of the venous and arterial pressure windows are set by these options. The
windows may be set to a fixed width for all treatments or the user may be allowed to set the
limits for each treatment in the Test & Options screen. The arterial window may be set to a
total width of 120, 160, or 200 mmHg. The venous window may be set to for
100 asymmetric, or 120, 160, 200 mmHg width. If 100 asymmetric limits are chosen, the
lower venous limit will tighten to the selected value after a short time delay. This value is
selected with the "100 Asymmetric Limits" parameter entry button in Service Mode. The
choices are 20, 25, 30, 35 mmHg. The lowest value that does not cause frequent nuisance
alarms should be chosen.
