1. Types of Dialysis  1. Hemodialysis  2. Peritoneal dialysis – just be aware of it’s existence

2. Hemodialysis  Hemodialysis -Dialysis works on the principles of the diffusion of solutes and ultrafiltration of fluid across a semi-permeable membrane. diffusionultrafiltration semi-permeable membrane diffusionultrafiltration semi-permeable membrane  Hemodialysis removes wastes and water by circulating blood outside the body through an external filter that contains a semipermeable membrane. The blood flows in one direction and the dialysate flows in the opposite. This maximizes the concentration gradient of solutes between the blood and dialysate  Ultrafiltration occurs by increasing the hydrostatic pressure across the dialyzer membrane. This usually is done by applying a negative pressure to the dialysate compartment of the dialyzer. This pressure gradient causes water and dissolved solutes to move from blood to dialysate, and allows the removal of several liters of fluid

5. Peritoneal Dialysis Peritoneal dialysis - uses the same principles as before however rather than extracorpeal membranes, uses patients own peritoneal membrane to move solutes across. Place dialysate bath into patient’s abdomen.
