Priming the Blood Circuit
There are two different ways to prime the blood circuit on 2008K hemodialysis machine—
Standard Prime method and Prime Amount method. The Standard Prime method allows the
operator to prime the blood circuit by controlling the flow of the saline manually. The Prime
Amount method is a machine option that is set in the Service Mode, and limits the amount of
saline used in the priming procedure to a preset volume. 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 line in the venous line clamp and the optical detector. 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, if not already attached, to the saline
port on the arterial bloodline. 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 heparin syringe into heparin pump. If the heparin pump is not
used, clamp the heparin line.
7. Press the Prime key on the control panel to stop the blood pump.
8. Press the blood pump Start/Stop key and run the blood pump at a rate of 150 ml/min.
Adjust the flow rate by pressing the  (up) or  (down) keys.
9. Fill the arterial drip chamber to an acceptable level using the  key (level adjust) on the
blood pump. Close the arterial pressure monitor line clamp and disconnect the line from
the arterial pressure port so the port is open to atmosphere.
Warning! The  Level Adjust key on the Blood Pump module can only be used to raise
the level in the arterial 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.
10. Run the 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.
