Q

DIfference between AV fistula and AV graft

A

In fistula, vein is sowed to artery, in graft tube is placed between the two
fistulas take 3 months to mature while grafts take 2-3 weeks
fistulas have longer survivals while grafts have shorter ones (synthetic material)
fistulas have few complications, grafts have increased infection rate

Q

What is KT/v

A

measure of total body water that is cleared of urea
V-VOD
K- clearence of urea

CCPD short cycle

A

during night

19
Q

CCPD long cycle

A

during day

20
Q

NIPD short cycle

A

during night

21
Q

NIPD long cycle

A

does not exist

22
Q

NTPD

A

long and short cycle during night

23
Q

What is CRRT

A

continous renal replacement therapy

24
Q

Who is CRRT for

A

ARF patients that can not tolerate Hemodilaysis. They are on constant 24/7 dialysis (slow)

25
What is the only CRRT without dialysate
CAVH (CVVH)
26
mechanism name for how blood is dialyzed in CAVH (CVVH)
convection
27
what is CVVHD
continous venovanous hemodialysis Has dialysate and waste is removed by diffusion.
28
difference between CVVHD and CVVHDF
increased rate in CVVHDF that
