Home Screen Monitoring
Button Data
During treatment, this button displays the current rate of ultrafiltration in
milliliters per hour (ml/hr). The rate ultrafiltration occurs is determined
by the values entered in UF Goal and UF Time, and the UF Profile
selected. UF Rate will automatically drop to 70 ml/hr when the UF Goal
is achieved (or 300 ml/hr if the high flux option in the "Test & Options"
screen is selected), or when blood flow is  90 ml/min. The rate flashes
when the UF pump is turned off and there is no ultrafiltration.
This button keeps a running total of the fluid drawn from the patient
through ultrafiltration. When the value displayed in UF Removed is
equal to the value entered in UF Goal, an alarm sounds and the
message, "UF GOAL REACHED" is displayed in the Status box.
Pressing the New TX key on the control panel resets this value to zero.
A sample of the ultrafiltrate can be obtained via the UF sampling tube
located adjacent to the bicarbonate rinse port.
This button displays the current dialysate flow rate. If "2X" is selected,
the flow rate will be indicated as follows: a800
The current temperature of the dialysate. If the temperature varies or 
2C from set point, this button turns red, an alarm sounds, a warning
message is displayed in the Status Box, and dialysate goes into
bypass. Touching this button allows the desired temperature to be set.
This button displays the current conductivity of the dialysate.
Pressing this button during treatment will open the "Dialysate" screen.
If the conductivity varies outside of the alarm limits, this turns the button
red, an alarm sounds, a warning message is displayed in the Status
Box, and dialysate goes into bypass
RTD (Remaining Time of Dialysis) This button acts as a countdown
timer displaying the amount of treatment time remaining. At the end of
treatment, (RTD = 0:00) an alarm sounds and the message, "RTD
ZERO" is displayed. Any alarm situation will stop the RTD countdown.
The TX Clock button is touched and confirmed to start or pause the
treatment. The green segment of the pie chart represents the amount
of treatment completed. The green segment grows as the treatment
progresses. The circle will be completely green when RTD is equal to
zero. During treatment, this button displays the message, "Tx Running."
Pressing this button will interrupt the treatment and the button will
display the message, "TX Paused." When the treatment is paused, the
green segment will change to yellow, the UF and heparin pumps stop
and SVS program pauses, and the RTD, UF, and heparin infusion Time
buttons stop counting down. The sodium content of the dialysate
remains at the profile level it was when the treatment was paused. The
blood pump and the dialysate flow, however, remain running.
