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 at zero for sequential dialysis, the button displays SEQ.
"2X" may be selected by scrolling up past 800. If this automatic
selection is set, the dialysate flow rate will be set to approximately 2
times the blood flow rate between 500 and 800 cc/min, in 100 cc/min
increments. When "2X" is selected and confirmed, the dialysate flow
rate will be indicated with the letter "a" preceding the dialysate flow rate,
such as: "a500".
Warning! Setting the dialysate flow to a rate that is too low
can adversely affect dialyzer clearance and reduce treatment
efficacy. If "2X" selects a flow rate below that prescribed, the
dialysate flow may be manually set to the desired value.
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 "Seq" dialysate flow is
selected, the temperature is "N/A", since there is no dialysate flow.
The actual conductivity is displayed. If the button is touched, 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.
Ultrafiltration (UF) Profile—Opens the "UF Profile" subscreen from
which a profile for executing variable rate ultrafiltration can be selected.
The button displays the current profile selection. For more information,
see "Setting a UF Profile" on page 62.
Sodium Variation System (SVS) Profile—This button opens the "SVS
Profile" subscreen from which the operator can select how sodium is
varied during the course of the treatment. For more information, see
"Sodium Variation System" on page 66.
