Dialysis

Length: 4 Pages 1062 Words

The topic of this paper is dialysis. Throughout the paper I will discuss the alternative names given for dialysis, reasons on why the test is performed, how the test is performed, how the test will feel, how to prepare for the test, risks that may occur, and lastly, some pictures of a dialysis machine and the instruments used during dialysis. There are several alternative names used for dialysis that include artificial kidneys, AV fistula, AV graft, hemodialysis, and peritoneal dialysis. Dialysis is performed to remove contaminants from the blood that could, and eventually, result in death in the absence of kidney function. The kidneys function as filters for the blood, removing products of amino acid breakdown. More than that, they serve to reclaim and regulate body water, maintain electrolyte balance, and ensure that the blood pH remains between 7.35 and 7.45. Without the function of the kidney, life is not possible (http://content.health.msn.com/content/asset/adam_test_av_graft). Dialysis serves to replace some of the functions of the kidney. Since dialysis is not a constant ongoing process, it cannot serve as a constant monitor as do normal functioning kidneys, but it can eliminate waste products and restore electro Continue...

After the 4 to 6 weeks the fistula needs to heal, needles can be placed so that arterial blood can be pulled off for dialysis, and the cleansed blood returns through the dilated vein. A special type of arterial and venous access is therefore established. The increased blood volume stretches the elastic vein to allow a larger volume of blood flow. Turbulent blood flow over the AV fistula is commonly felt and termed a thrill (http:content. Dennis is reinfusing a patient, that means returning the blood to the patient. The patient infuses a solution into the abdominal cavity through a permanently implanted tube. An AV graft may be used for people whose veins are not suitable for an AV fistula.

External access involves two catheters, one that is placed in an artery, and one in an adjacent vein, and then both are joined externally. Blood pressure medications are frequently withheld 6 to 12 hours before homodialysis, as are water-soluble vitamins. comcontentassetadam_test_av_graft).
