Chapter 2—Daily Preparation for Treatment
10. Press the Prime key on the control panel. Run the blood pump to flush additional saline
through the dialyzer until fluid level is detected in the venous drip chamber. The blood
pump will stop when the level detector detects an acceptable level of fluid.
11. Press the RESET key on the control panel to restart the blood pump and continue
flushing saline through the blood circuit in accordance with established facility protocol
regarding dialyzer rinsing.
12. After the required saline amount has passed through the dialyzer, press the Start/Stop
key on the blood pump to stop the pump.
13. Clamp the patient end of the venous line.
14. Adjust the fluid levels in the drip chambers by pressing the appropriate
adjust keys. Do not allow the transducer protectors to become wet.
15. Connect the venous line to the arterial line. Unclamp both lines and press the blood
pump Start/Stop key to start the pump and begin recirculation.
16. If necessary, press the RESET key to clear any alarms.
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 2X
dialysate flow is selected, be sure that the dialysate flow rate is at least the minimum
required rate.
Prime Amount Method
1. Hang a saline bag and attach an administration line to the saline port on the arterial
bloodline. Gravity prime the pre-pump arterial segment with saline. When primed,
clamp off the patient end of the tubing.
2. Set up the heparin syringe and prime the heparin line segment with heparin. If the heparin
pump is not used, clamp the heparin line.
3. On the control panel, press the Prime key.
4. Press the blood pump Start/Stop key and run the blood pump at a rate of about 150-200
ml/min. Adjust the flow rate by pressing the
line until saline has reached the dialyzer end of the line. Ensure that the pump segment is
free of bubbles.
5. Fill the arterial drip chamber to an acceptable level using the
key on the blood pump.
Warning! The Level Adjust key 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.
