Data
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. The UF Removed
button can only be edited when Dialysis is paused.
This button displays the current dialysate flow rate. If 1.5x or 2x is
selected, the flow rate will be indicated as follows: a800. See "Using
Auto Flow" on page 249 for more information.
To turn off dialysate flow, select the Dialysate Flow button and either
use the  key to scroll down to OFF or press the 0 key and then press
the CONFIRM key. To turn dialysate flow back on, select the Dialysate
Flow button, set it to the desired value, and press the CONFIRM key.
Note: The value displayed in the Dialysate Flow button will
flash when dialysate flow is set to 'OFF' from the "Dialysate"
screen (see page 65 for more information). Select the
Dialysate Flow on/off button on the "Dialysate" screen and
press the CONFIRM key to turn the dialysate flow back on
when desired.
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. Selecting this button allows the desired temperature to be set.
This button displays the current conductivity of the dialysate.
Selecting 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 selected 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."
Selecting and confirming 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.
