亞洲情色a 亞洲最大 情網va先鋒Dialysis is a process that duplicates kidney function for patients with failed kidneys by reducing waste and excess fluids. Without frequent and ongoing dialysis treatments three times weekly patients cannot survive. There are two primary types of dialysis: hemodialysis and peritoneal dialysis. Both are based on principles of osmosis and diffusion. Osmosis is the tendency of water to move from a low concentration of particulates to a higher concentration, and diffusion is the tendency of particles to distribute evenly throughout a solution leading to homeostasis. Together, osmosis and diffusion, working in conjunction with a membrane of some sort, comprise dialysis.

However waste in the blood, consisting of excess water and other impurities (delete comma) are filtered out and removed by the membrane with the help of a solution called dialysate. This solution also which makes dialysis possible, contains essential nutrients sodium, potassium, calcium, magnesium and other electrolytes balancing the patient’s blood pH.
For a small percentage of ESRD patients, peritoneal dialysis is chosen, which uses the lining of the patient’s abdomen as the dialyzing membrane. This lining is called the peritoneal membrane (thus the name peritoneal dialysis). The majority of patients receive hemodialysis in the U.S. and world-wide.
