Appendix A—Single Needle Dialysis (Optional)
Priming the Single Needle Blood Circuit
There are two different ways to prime the blood circuit on the 2008K hemodialysis machine:

Standard Prime method: This method allows the operator to prime the blood circuit
by controlling the flow of the saline manually.

Prime Amount method: This method limits the amount of saline used in the priming
procedure to a preset volume. The preset volume (Prime Amount) is set in Service
Mode.
Prime the blood circuit according to how your machine was set up. Follow your unit protocol
or dialyzer manufacturer's instructions for priming and rinsing dialyzers.
Standard Prime Method
1. Connect the dialyzer end of the arterial bloodline to the arterial port of the dialyzer.
Rotate the dialyzer to the arterial end down position.
2. Connect the dialyzer end of the venous bloodline to the venous port of the dialyzer.
3. 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.
4. Hang a saline bag and attach an administration line to the saline port on the arterial
bloodline below the arterial blood pump. Aseptically spike the saline bag.
5. Gravity prime the patient end of the arterial bloodline below the saline "T" with saline.
When primed, clamp the patient end of the arterial bloodline.
6. If the heparin pump is to be used: connect the heparin syringe, prime the heparin line
with heparin, and load the heparin syringe into the Heparin Pump module. If the heparin
pump is not used, clamp the heparin line.
7. Press the Prime key on the control panel.
8. Press the Start/Stop key on the Arterial Blood Pump module and run the pump at a rate
of 150 ml/min. Adjust the flow rate by pressing the  (up) or  (down) keys. The
compliance chamber will automatically fill to an acceptable level.
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.
9. Run the arterial blood pump to flush additional saline through the dialyzer until a fluid
level is detected in the venous drip chamber. The blood pump will stop when the level
detector detects an acceptable level of fluid.
