Testing the 2008T Hemodialysis Machine

Before beginning treatment, the 2008T hemodialysis machine should undergo Pressure and
Alarm tests to ensure that it is functioning properly. There are four different ways to run self-
tests for the machine:

If the machine has been automatically started up using the Auto Start program and the
Auto Prime program (functional software version 2.70 or later with BlueStar Premium)
has completed, then all testing has already been automatically run, turn to page 75 to
enter the treatment parameters and prepare to connect the patient to the machine for
treatment.

If the bloodlines have not been primed yet, the majority of self-tests can be run before
selecting the Auto Prime program (during which the remaining four self-tests will be
completed). Select the Both Tests button in the "Test & Options" screen to run the Auto
Start self-tests before priming then turn to page 64 to run the Auto Prime program.

If the Auto Start program has been run but Auto Prime is not desired, then four alarm
self-tests remain: the Level Detector, Arterial Pressure, Venous Pressure, and TMP self-
tests (see below). Select either to Both Tests or the Alarm Test button to complete the
remaining self-tests. Turn to page 73 to perform the final setup procedure.

If the machine has not been automatically started up using the Auto Start program and the
bloodlines have already been primed, all pressure and alarm tests must be run at this time.
Select the Both Tests button in the "Test & Options" screen to start the test, see below:
Note: The 2008T hemodialysis machine can be configured so that this testing is mandatory
after power up with the Service Mode 'Forced Test' option selected (see page 303 for more
information). In this case, the test will start on its own shortly after the operator powers the
machine on.
To run the test sequence using the Both Tests, Alarm Test, or Pressure Test button,

The dialyzer lines must be connected to the shunt with the interlock door closed.

The machine must be in an alarm-free condition by allowing sufficient time for the
dialysate to reach proper conductivity and temperature. This takes about five minutes
from the time the concentrate is confirmed on the "Dialysate" screen (see Figure 23 on
page 54).

Arterial and venous monitor lines must be clamped and removed from the pressure
monitor ports so the monitor ports are open to atmosphere.

UF and SVS must be off.
Warning! It is essential that the 2008T hemodialysis machine's balancing system is
operating properly. The machine must successfully complete a Pressure test before each
treatment, especially when using high-flux dialyzers.
Note: If the Service Mode 'Independent Cond Test' option is enabled (functional software
version 2.70 or later), the Independent Conductivity self-test will be listed among the self-
tests. Running this test will independently verify the conductivity of the dialysate. If the
bibag disposable is the bicarbonate source for the treatment, the Independent
Conductivity/pH self-test will be listed and the machine will independently verify both the
conductivity and pH of the dialysate. See page 310 for more information.
