Appendix A—Single Needle Dialysis (Optional)
Warning! The  Level Adjust key on the Arterial Blood Pump module can only be used
to raise the level in the compliance chamber. Do not press the  Level Adjust key so long
that the pressure transducer protector becomes wet. Wet transducer protectors must be
replaced to avoid erroneous pressure readings.
8. The arterial blood pump will start and continue to run until the pre-set amount of saline
has been flushed through the circuit. When the blood pump stops, clamp the patient end
of the venous bloodline.
9. Insert the venous bloodline into the venous line clamp and optical detector on the Level
Detector module. Close the optical detector door.
Warning! The tubing beneath the venous drip chamber must be inserted into the venous
line clamp and the optical detector.
10. Adjust the fluid level in the venous drip chamber by pressing the appropriate  or 
level adjust keys on the Level Detector module. Close the venous pressure monitor line
clamp and disconnect the monitor line from the venous pressure port so the port is open
to atmosphere.
11. Aseptically connect the patient end of the arterial bloodline to the patient end of the
venous bloodline using a sterile recirculation piece. Unclamp both lines.
12. Set the arterial blood pump rate to 350-400 ml/min. Press the Start/Stop key on the
Arterial Blood Pump module to start the pump and begin recirculation. Do not insert the
single needle blood pump segment into single needle blood pump. If necessary, press the
RESET key to clear any alarms.
13. Ensure that the extracorporeal blood circuit is free of air bubbles.
Note: The dialysate lines will have to be attached at the appropriate point during the
priming process, depending on facility procedure and manufacturer's instructions. If 1.5x
or 2x dialysate flow (Auto Flow) is selected, be sure that the dialysate flow rate is at least
the minimum required rate.
