How is air removed from a dialyzer?
How is air removed from a dialyzer? To remove air from a dialyzer, prime normal saline into the dialyzer from the bottom. This is accomplished by attaching the bloodlines to the dialyzer and then turning the dialyzer so that the venous end is up.
What are the types of dialyzer?
In addition, dialyzers are internationally classified into three types: low-flux, high-flux, and protein-leaking.
What is dialyzer reuse?
Dialyzer reuseis the practice of you, the patient, using the same dialyzer for multiple treatments. Dialyzers are not just reused, they are reprocessed. The reprocessing procedure involves cleaning, testing, filling your dialyzer with a sterilant (Renalin®Cold Sterilant), inspecting, labeling, storing and rinsing your dialyzer before it is reused for your next treatment. Your dialyzer will be reprocessed carefully after each use by trained personnel. Detailed records of the dialyzer history will be kept. This will ensure that the dialyzer is safe for you to use again.
What happens to dialyzer after treatment?
7. Post treatment– When your treatment is completed, your dialyzer will be capped and sent to the dialyzer reprocessing room. Your dialyzer will be reprocessed, and the cycle will be repeated.
What happens if dialyzer fails volume test?
a. During the cleaning phase, any blood that remains in your dialyzer at the end of treatment is flushed out of the fibers. b. A volume testis performed on the dialyzer to ensure that the fibers that carry the blood are open and not clotted off. If your dialyzer fails the volume test, it will be thrown away , and a new dialyzer will be preprocessed for your next treatment.
