Chapter 5: Hemodialysis Flashcards
What happens when kidneys lose their ability to function?
Fluid, minerals and waste products that are normally removed from the body in the urine begin to build up in the blood.
Why people won’t live very long when their kidneys lose their ability to function?
Because the wasted products build up in the blood and will eventually kill the person.
What takes over the function of the failing kidneys to remove fluid and waste?
Dialysis.
What are the two types of Dialysis?
Hemodialysis and Peritoneal Dialysis.
During Hemodialysis, the blood passes through what?
Through a filter called dialyzer and is forced into very thin, hollow fibers.
What happens as the blood passes through the hollow fibers?
Dialysis fluid passes in the opposite direction on the outside of the fibers.
What contains the dialysis fluid when waste products from the blood move into the dialysis fluid?
Water and chemicals that safely remove wastes, extra salt and fluids from blood.
What happens to the filtered blood after waste products from the blood move into the dialysis fluid?
Remains in the hollow fibers and returns to the body.
What is the term used describe the place on the body where blood flows from and returns to the body during hemodialysis?
Vascular access.
What is considered an Arteriovenous (AV) Fistula for vascular access?
“Gold Standard”
What does an AV Fistula allows in a surgical connection between an artery and a vein?
Allows increased blood flow through the vein, which helps enlarge and strengthen the vein, it also allows a higher rate of blood to flow back and forth to a dialysis machine.
