Hemodialysis Teaching Tool

Gretchen Crockett

Main Function of Hemodialysis

Acting like an artificial kidney, it removes waste and extra water from the blood. (Pellico, 756)

How Is Waste Removed?

Waste is removed via diffusion. Diffusion is a process that moves waste from an area of higher concentration to an area of lower concentration. In your case, waste from the blood moves into the artificial kidney also known as a dialyzer. (Pellico, 765)

How Is Water Removed?

Water is removed via osmosis. Osmosis is the process by which water moves from an area of high solute concentration to an area of low solute concentration. (Pellico, 765)

Contact your doctor if you:


  • See signs of infection
  • Feel a pulsation at site
  • Don't feel a vibration (thrill)
  • Experience numbness of hand or at site


(Pellico, 760)

What Is the Time Commitment?

3-5 hours of treatment, usually three times weekly. However, your doctor will determine the length and frequency.
