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
