Warning! After selecting and confirming a test button, the machine will beep. As a test of
the audible alarm system, make certain that the sound occurs. If the machine fails this or
any of the Pressure, Alarm, and Diasafe tests and the cause cannot be corrected, or if it fails
subsequent tests, it should not be used for treatment. Remove the machine from service and
have it inspected by a qualified technician to correct the problem.
The 2008K hemodialysis machine can be set up to perform online PHTs during treatment.
These tests routinely happen every 12 minutes, and check the integrity of the hydraulic
system. In the event of a failure, an alarm sounds and a warning message is displayed in the
status box. For more information see “Online Pressure Holding Test” on page 116.
If your machine is set up with the automatically activated Diasafe test valve, you may initiate
the Diasafe test from this screen. The date of the last test and test result is displayed.
Recirculation and Final Set-Up Procedure
1. Rotate 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.
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 dialysate lines to dialyzer by matching the color of the quick connector to the
color of the blood tube fitting. When done correctly, the red arterial blood tubing
connector and the red quick 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 arterial and venous monitor lines to their respective ports. Unclamp the lines.
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 
(d
own) 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.
