Principles of hemodialysis pdf

Dialysis evolves as we learn more about the uremic condition. In its earliest versions, the major transport process was diffusion, the spontaneous movement of particles down a concentration gradient. This required concomitant ultrafiltration generated by osmotic, oncotic, or hydrostatic pressures. Consequently, ultrafiltration's solvent drag effects led to an appreciation of the importance How a dialysis machine works. 1) Blood is pumped out of a patient, often via an arteriovenous fistula. 2) An anticoagulant is added to prevent the blood from clotting. 3) Blood flows past the dialysate separated by a semi-permeable membrane. 4) Blood is pumped back into the body. In hemodialysis principles pdf, the therapy is accomplished through artificial kidney (Kidney Dialyzer) which consists of a semipermeable membrane like plastic or cellulose which acts as Erythrocytes get damaged in renal failure. It contains pores of molecular size but larger than urea or small molecules and hence can let water, sodium and Principles of Peritoneal Dialysis P eritoneal dialysis is a technique whereby infusion of dialysis solu-tion into the peritoneal cavity is followed by a variable dwell time and subsequent drainage. Continuous ambulatory peri-toneal dialysis (CAPD) is a continuous treatment consisting of four to five 2-L dialysis exchanges per day (Fig. 4-1 A Principles of Peritoneal Dialysis P eritoneal dialysis is a technique whereby infusion of dialysis solu-tion into the peritoneal cavity is followed by a variable dwell time and subsequent drainage. Continuous ambulatory peri-toneal dialysis (CAPD) is a continuous treatment consisting of four to five 2-L dialysis exchanges per day (Fig. 4-1 A Hemodialysis may seem complex, but it is based on simple scientific principles. This module will help you understand these principles and how they are used in dialysis. Dialysis replaces three main kidney functions: 1. Removing wastes from the blood 2. Removing excess fluid from the blood 3. Keeping electrolytes (electrically charged particles Notable treatment-related side effects include cramps, hypotension, problems with blood access, and reactions to dialyzer membrane materials. Far from treating underlying disease, hemodialysis extends life and permits the expression of much progressive multisystem disease. Cardiovascular disease is the most common comorbid condition and cause Basic Principles of Hemodialysis (virtual) This course will address the theory of the basic principles of hemodialysis. You will learn the mechanism of blood purification by following a demonstration of diffusion, convection, and ultrafiltration.
