9. Disinfection
3. Place the container of prediluted sodium hypochlorite on the
floor near the water supply valve.
4. Turn off the water supply.
5. Disconnect the incoming water line from the water supply
valve.
6. Place the free end of the incoming water line in the container
of prediluted sodium hypochlorite.
7. Raise the container of prediluted sodium hypochlorite above
the height of the top of the hydraulics compartment.
8. Turn on the Instrument and start the Rinse Mode.
9. Infuse the prediluted sodium hypochlorite for approximately 15
minutes.
10. After the 15-minute infusion, make sure that most of the
sodium hypochlorite solution (approximately 4.5 L) has been
infused.
If the solution was not infused, prime the incoming water line
with water and infuse the sodium hypochlorite solution by
repeating Steps 6, 7 and 9.
11. Connect the incoming water line to the water supply valve.
12. Rinse the Instrument until it is free of sodium hypochlorite.
13. After 15 minutes, obtain a sample of the rinse solution and
check for residual sodium hypochlorite using a test specific for
sodium hypochlorite.
a. If the residual sodium hypochlorite content is within
acceptable limits, the Instrument can be prepared for
dialysis.
b. If the residual sodium hypochlorite content is not within
acceptable limits, continue to rinse the Instrument until the
level is acceptable.
WARNING
Make sure that the determination test shows a
sufficiently low level of disinfectant in the rinse solution
before dialysis. Refer to the attending physician’s
directives for the acceptable limit and the AAMI
standard for hemodialysis.
To ensure that the disinfectant level in the dialyzer
circuit is below a level acceptable for patient safety,
sample the rinse solution in the dialysate lines.
