5. Close the dialysate sample port: Flip the switch away from the trigger and release the
trigger (see "The Shunt Interlock" on page 34 for picture of dialysate sample port with
the switch pushed away from the trigger). The dialysate sample port is now closed again.
6. Disconnect the syringe from the dialysate sample port and discard first sample.
7. Reconnect the syringe to the dialysate sample port, open the dialysate sample port and
collect the required amount of dialysate for testing per clinic protocol.
Warning! When connecting a syringe directly to the dialysate sample port, do not inject
used dialysate back into the system.
Note: If the testing sample is measured in a container, be sure to rinse the container with
dialysate at least three times in order to bring the container up to the temperature of
dialysate for proper conductivity.
8. Close the dialysate sample port and disconnect the syringe. Use the facility's standard
measuring devices and follow the device's instructions to test the dialysate sample per
clinic protocol for:

Conductivity - for example, set the meter to read conductivity, connect the syringe,
and observe the readings. If the reading is not reasonably close to the theoretical
conductivity value (TCD), check the meter's calibration and retest the dialysate
sample. If the reading is still not within limits, take the 2008T hemodialysis machine
out of service and contact a qualified technician.

pH - for example, using pH paper, dip the indicator strip in the dialysate for one (1)
second and immediately compare it to the manufacturer's color chart. The color on
the indicator strip will indicate the dialysate's pH. If the reading is not between 6.9
and 7.6, test with another pH indicator strip. If the reading is still not within the
specified limits, take the 2008T hemodialysis machine out of service and contact a
qualified technician.

Residual disinfectant - see "Testing for Disinfectant" on page 151 for more
information
Warning! After testing the dialysate through independent means (e.g., using a conductivity
meter and pH paper or meter), verify that the conductivity is reasonably close to the
theoretical conductivity value (TCD) and the pH is between 6.9 and 7.6. The machine must
also be free of residual disinfectant. If these conditions are not met, do not initiate dialysis.
9. Document the conductivity, pH, or residual disinfectant test readings in the patient
treatment record or flow sheet.
Note: Make sure the dialysate sample port switch is locked away from the trigger and the
trigger is not pressed down after taking a dialysate sample. Allowing the trigger to stay
depressed will cause fluid leaks.
