Expert Answer:

  • Dialysis fluid is a solution of pure water, electrolytes and salts, such as bicarbonate and sodium.
  • The blood of the hemodialysis patient has a high concentration of waste, while the dialysate has a low concentration of waste.
  • Due to the difference in concentration, the waste will move through the semipermeable membrane to create an equal amount on both sides.
  • The dialysis solution is then flushed down the drain along with the waste.
  • The electrolytes in the dialysis solution are also used to balance the electrolytes in the patient’s blood.
  • The extra fluid is removed through a process called filtration.
  • The fluid is pushed off by higher pressure on the blood side than on the dialysate side.
