Fresenius Final Exam Terminology and Such TECH Section 2023
(Complete Solution)
Available weight (AW) - The difference between the pre-weight and the EDW
(pre-weight - EDW = AW)
Estimated Dry Weight (EDW) - An estimation of what the patient's weight would be if his or her
kidneys functioned properly. This is a doctor's order
Pre-weight - The patient's weight before the treatment began
Post weight - The patient's weight after the treatment is completed
Last weight - Post weight from the patient's last treatment
Target weight - AW + prime and rinse back and any additional fluids...including what the patient is
going to drink and any IV medications (abx) and normal saline flushes
Goal - Target weight expressed in ml
Gain - Pre-weight - last weight
Loss - Pre-weight - post-weight
Kidney's 7 functions - Acid/base imbalance
Water balance maintenance
balance
, Toxin removal
Blood pressure regulation
Erythropoietin production
Vitamin D metabolism
Electrolyte
Chloramine - A combination of chlorine (bleach) and ammonia
Diasafe Filter - Found on the back of the machine and is the last filtration the dialysate meets before
going to the patient. It allows for the delivery of ultrapure dialysate.
What is the largest factor that impacts ultrafiltration - Pressure
Countercurrent flow - The blood and the dialysate flow in opposite direction. Blood flows down
(arterial to venous), dialysate flows up (venous to arterial). This allows for better clearance and
diffusion
Blood alarm - Stops the blood pump- therefor blood in the lines stop circulation. Examples) blood
leak, air detector, venous pressure, arterial pressure, TMP
Dialysate Alarm - Dialysate goes into bypass and is not delivered to the dialyzer. The blood pump
does NOT stop
Examples): Conductivity high- see crenation, conductivity low- see hemolysis, temperature too high
or too low
Hypotonic solution - Contains less particles. Cells will swell - hemolysis can occur
Hypertonic - Containing more particles, cells will shrink and crenation can occur
