    Study Notes

    • Dialysis is a therapy used to remove wastes from the blood of patients with kidney failure.
    • There are two main types of dialysis: hemodialysis and peritoneal dialysis.
    • In hemodialysis, blood is filtered outside the body in a machine, using a vascular access created through a minor surgery.
    • The blood flows through tiny tubes surrounded by dialysate in the machine, allowing small molecules to pass through semipermeable membranes via osmosis and diffusion.
    • Hemodialysis is typically performed as 4-hour treatments, 3 times a week in a dialysis center, with risks of complications such as blood infection and internal bleeding.
