Chapter 3—Setting Treatment Parameters
Button

Function
Displays the total amount of ultrafiltration removed in ml. The counter
keeps track of the UF in 1 ml. increments.
Warning! UF Removed must be reset to 0 before initiating
treatment. If the UF Removed is not reset, the amount
displayed will be used in the UF calculation, resulting in
incorrect UF removal from the patient.
The prescribed dialysate flow rate, in ml/min, is entered here. The rate,
displayed in ml/min, can be entered from 0 to 800 in increments of 100.
If flow is set for sequential dialysis, the button displays 'SEQ'. For more
information on sequential dialysis, see page 81.
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.
1.5x or 2x auto flow may be selected by scrolling up past 800. If this
automatic selection is set, the dialysate flow rate will be set to
approximately 1.5 or 2 times the blood flow rate between 500 and 800
ml/min, in 100 ml/min increments. When 1.5x or 2x is selected and
confirmed, the dialysate flow rate will be indicated with the letter "a"
preceding the dialysate flow rate, such as: "a500". See page 249 for
more information.
Warning! Setting the dialysate flow to a rate that is too low can
adversely affect dialyzer clearance and reduce treatment
efficacy. If 1.5x or 2x selects a flow rate below that prescribed,
the dialysate flow may be manually set to the desired value.
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 button and press the CONFIRM key to turn the
dialysate flow back on when desired.
The desired temperature of the dialysate in degrees Celsius is set here.
Once this setting is confirmed, the button will display the actual
temperature. The allowable temperature setting range from 35 C to 39
C. A temperature alarm occurs when the actual temperature rises or
falls 2 C beyond the set temperature. If the dialysate flow is set to OFF
or SEQ, the temperature is "N/A", since there is no dialysate flow.
The actual conductivity is displayed. If the button is selected, the
"Dialysate" screen is brought up.
RTD (Remaining Time of Dialysis)—At the start of the treatment, the
time entered in the UF Time button is automatically transferred to the
RTD button if UF removed is 0. If it is necessary to change the
treatment time, RTD can be entered here. A dialysate or blood alarm
will stop this timer.
