- osmosis
- ultrafiltration
- convection
what is the most effective RRT option?
hemodialysis
what is the most tolerated RRT option?

what are the 3 most common ADRs of Hemodialysis?
- disequilibrium
- dialysis-induced hypotension
- muscle cramps
which method for hemodialysis takes the longest time to mature?
AV fistula
how long does it take for the
AV fistula to mature?
1-2 months
how long dies it take for the AV graft to mature?
2-3 weeks
which method for hemodialysis has the longest survival rate?
AV fistula
which method for hemodialysis has the lowest rates of complications?
AV fistula
which method for hemodialysis has a shorter survival rate
AV grafts
which method for hemodialysis has higher rates of complications?
AV grafts
which method for hemodialysis has the least desirable HD access?
venous hemodialysis catheter
which method for hemodialysis is the most expensive?
AV fistula
what type of patients are venous hemodialysis catheters used in? 4
- small children
- patients without viable access for grafts or fistulas
- patients with vascular disease
- morbidly obese
type of dialysis where fluid is instilled into the peritoneal space that draws out waste products from the blood
peritoneal dialysis
what acts as a dialysis membrane in peritoneal dialysis?
peritoneal membrane
what are 5 ADRs seen with peritoneal dialysis?
- exacerbation of diabetes
- chemical peritonitis
- fibrin formation in dialysate
- malnutrition
- mechanical problems
a method of hemodialysis that removes fluid and wastes from a patient in a slow manner that is less likely to cause hypertension
continuous renal replacement therapy
method that treats fluid overload in cases when waste products do not need to be removed or the pH levels do not need to be corrected
slow continuous ultra filtration
method that removes large volumes of fluids and waste and uses replacement fluids to maintain electrolyte and acid base balance
continuous veno-venous hemofiltration
method that uses diffusion along with dalysate solution to boost the removal of waste products
continuous veno-venous hemodialysis
method that allows for the removal of large volumes of toxin-filled plasma, while still maintaining electrolyte balance
continuous veno-venous hemodiafiltration
