-measured by green post BUN lab

What affects Kt/V? - Answer - time of tx
-frequency of tx
-increasing BFR and DFR increase Kt/V
Needle gauge sizes vs. BFR - Answer - 17g=200-250
- 16g = 250-350
- 15g = 350-450
- 14g = 450 and ^
procedure for post BUN lab draw - Answer turn off UF
DFR to 300
decrease BFR to 100 ml/pm
WAIT 15 SEC.
draw from arterial line port
What causes Kt/V to be falsely high? - Answer if you take it before waiting the full 15 secs
what causes kt/v to be falsely low? - Answer if you wait longer than 15 sec to take it

- they will give fluid, slow BFR, turn off UF
what causes angina during dialysis? - Answer dehydration and electrolyte imbalance
what is disinfectant infusion? + s/s - Answer when there is leftover disinfectant in the machine
- s/s is pain at venous needle site at beginning of tx
