Creatinine
What is a solution?
Fluid that contains a dissolved solute
Blood
What is a solution in the body?

What is a solution in dialysis?
Dialysate
Water
Acid
Bicarbonate
Where is water in the body?
Intracellular Fluid 70%
Plasma (blood)10%
Interstitial 20%
How is fluid removed in dialysis?
Osmosis
Where is fluid removed during dialysis?
Plasma (blood)
Where is most of the fluid located in the body?
Intracellular
What does TMP mean?
, Transmembrane Pressure
What does the TMP measure
the pressure difference across the membrane fibers inside the dialyzer
THe pressure across the dialyzer membrane
What is osmosis?
movement of fluid from an area of low solute concentration to an area of high solute
concentration until equilibrium is reached
What is diffusion?
The movement of particles or solutes from an area of high solute concentration to an
area of low solute concentration until equilibrium is reached?
