pesentation on haemodylysis
- 2. In Australia, approximately, 75% of all patients use haemodialysis. In haemodialysis, the blood is circulated and cleansed outside the body via a haemodialysis machine. The blood circulates through an artificial kidney, where it is cleansed of wastes and excess fluid. Each treatment generally lasts about five to six hours and is performed at least three times per week. If desired and recommended by your physician, overnight and more frequent dialysis at home is also possible. Dialysis is the process of cleansing or filtering the blood and removing excess fluids. The filter used to cleanse the blood in dialysis treatment is a semi-permeable membrane, i.e. a thin material with holes large enough to let small particles (up to a particular size) through but small enough to retain large particles. The body’s excess water and waste products filter from the blood across the membrane and are washed away by the dialysis solution. Large particles, such as blood cells and proteins, stay behind in the blood where they continue to do their work. There are two methods of dialysis treatment:
- 4. The kidneys are two vital organs, located in the back of the abdominal cavity on either side of the spine, slightly above the small of the back. Each kidney is bean shaped, weighs approximately 150 grams and measures 11cm x 6cm (the size of a clenched fist). Each kidney is composed of about a million minute filters, which remove waste products and excess fluid from the blood. The major function of the kidneys is to control the fluid and chemical balance of the body.
