PRINCIPLES OF DIALYSIS

Question 1

Blood is cleaned using the scientific principles of ____, ____, and ____.

Answer 1

diffusion, osmosis, and ultrafiltration.

Question 2

Diffusion:

Answer 2

movement of solutes (urea, electrolytes, creatinine, smaller drugs,
etc.) across a semi permeable membrane from higher concentration to lower concentration.

This is how waste products and extra electrolytes are removed from the blood and how additional electrolytes that are needed are given to the patient.

Question 3

Diffusion rate is affected by ?

Answer 3

concentration gradient, temperature, countercurrent flow

Question 4

Osmosis:

Answer 4

movement of water from lower concentration of solutes to higher
concentration

Question 5

Ultrafiltration (UF):

Answer 5

use of both negative and positive pressure to pull excess

fluid from the patient.
