Recirculation and Final Set-Up Procedure with Single Needle Blood
Pump
Note: If you are using a reused dialyzer, you cannot run recirculation with the single needle
blood pump segment inserted. Recirculation is achieved with the arterial blood pump.
1. Rotate the dialyzer to arterial inlet up.
2. Check the conductivity and pH of the dialysate and test for residual disinfectant before
connecting the dialysate lines to the dialyzer. For more information on collecting a
dialysate sample for testing, see "Testing the Dialysate" on page 256.
Warning! Always verify the conductivity and approximate pH of the dialysate solution
through independent means (e.g. using a conductivity meter or pH paper or meter, as
applicable) before initiating each dialysis treatment. Verify that the conductivity is
reasonably close to the theoretical conductivity value (TCD) and the pH is between 6.9 and
7.6. If they are not, do not initiate dialysis.
3. Connect the dialysate lines to the dialyzer by matching the color of the dialyzer connector
to the color of the blood tube fitting and then close the shunt door. When done correctly,
the red arterial blood tubing connector and the red dialyzer connector of the dialysate line
should be connected to the corresponding ports at the top of the dialyzer. This is to create
a counter-current flow (blood flowing from top to bottom, dialysate flowing from bottom
to top) inside the dialyzer to maximize clearance.
4. Pull on the dialyzer connectors to make sure they are firmly connected to the dialyzer.
Note: All dialyzer connectors must be fastened tightly to prevent air from entering the
dialysate circuit or to prevent dialysate from leaking from the dialyzer.
5. Reconnect the venous monitor line to the venous pressure port. Unclamp the venous
pressure monitor line.
6. When the dialysate compartment is filled, rotate the dialyzer so the arterial inlet is down.
7. After priming the extracorporeal blood circuit, press RESET to clear all alarms. Set the
blood pump rate to 350-400 ml/min and start the blood pump to begin recirculating the
saline through the circuit.
8. Press the  (down) key on the Level Detector module to lower the fluid level in the drip
chamber. Verify that the blood pump stops and the venous clamp occludes.
Warning! The test of the level detector system must be run as a precaution and aid to
identifying potential failures. Remove the machine from service if it fails this test.
9. Press the  (up) key on the Level Detector module to raise the fluid level in the drip
chamber to an acceptable level.
10. Check blood tubing to ensure that there are no kinks, especially between the blood pump
and the dialyzer.
