DIALYSIS Flashcards
a type of
kidney replacement
therapy that
removes metabolic
waste products,
and toxins, as well
as excess fluid and
electrolytes from
the blood
DIALYSIS
required due to end-stage renal disease, which means the kidneys have lost almost all their
function.
can also be used to correct fluid, acid-base, and electrolyte imbalances, and to treat drug overdoses
DIALYSIS
Two types of dialysis
HEMODIALYSIS and PERITONEAL DIALYSIS.
To perform dialysis,
vascular access for
- will be needed.
hemodialysis
To perform dialysis,
abdominal access for
peritoneal
dialysis
temporary venous
access can be obtained
through a catheter in the
- for hemodialysis in an
acute setting.
internal jugular or femoral
vein
Temporary Catheter HEMODIALYSIS
ACUTE
When permanent access is
needed for long-term
hemodialysis, an
- is created surgically in the patient’s arm.
arteriovenous or AV fistula or graft
an
arteriovenous or AV fistula or graft creates a
connection between a small artery and a vein, which causes the vein to become “-,”
meaning it increases in size, develops thicker walls and blood flow is increased.
“arterialized
vascular access dialysis
HEMODIALYSIS
ACUTE HEMODIALYSIS
Temporary Catheter in:
Internal Jugular Vein
Femoral Vein
AV fistula: created surgically, vein is arterialized
LONG TERM HEMODIALYSIS
peritoneal access dialysis
PERITONEAL DIALYSIS
Permanent Access HEMODIALYSIS
LONG TERM HEMODIALYSIS
movement of solutes
DIFFUSION
the health education platform that makes learning easy and fun, but in this case, it refers to the movement of fluid through a semipermeable membrane from an area of lesser solute concentration to an area of greater solute concentration.
Osmosis
can be obtained by inserting a catheter into the peritoneal cavity.
PERITONEAL DIALYSIS
the movement of solutes from a greater concentration to a lesser concentration until the two solutions have the same concentration of solutes on either side of a semipermeable membrane.
Diffusion
when a driving pressure moves fluid and solutes across a semipermeable membrane.
ultrafiltration
PRINCIPLES OF DIALYSIS
DIFFUSION, OSMOSIS, ULTRAFILTRATION
movement of fluid
OSMOSIS
driving pressure moves fluid & solutes across membranes.
ULTRAFILTRATION
One of the most important components is the -, which acts like an artificial kidney.
dialyzer
the dialyzer has two compartments separated by a semipermeable membrane:
blood compartment and
dialysate.
