What Is A Home Dialysis Unit And How Does It Work
Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure. Hemodialysis remove wastes and excess water from the blood by circulating blood outside the body through an external filter, called a dialyzer. Blood and dialysate flow through in opposite directions and the ...Read more
Filter, toxins: Dialysis does the work of kidney- removing fluids andtoxins. Blood from the patient flows on one side of the chamber and the dialysate solution which contains the optimal concentration of electrolytes on other side of the chamber. Electrolytes move along the concentration gradient, so toxins which are high in the blood, goes to the dialysate solution. ...Read more
Artificial kidney: The principle of dialysis machine is hard to explain in 400 characters. Like a human kidney, it filters impure blood under pressure; excess water is removed; blood toxins (prea, phosphorus, and many others) diffuse out in to the dialysate (the clean artificial fluid put in to the machine); some electrolytes might diffuse back in to blood. The relatively clean blood diffuses is returnd to the patnt. ...Read more
Blood cleaning: Blood is pumped into a filter that allows toxins to pass into a salt solution that carries them away while delivering bicarbonate (sodium bicarbonate) and other needed minerals. Excess fluid can be removed with the filter also, the blood then returns to the patient without the toxins, with less water and with corrected acid base status. ...Read more
Filters blood.: It's a complicated process, but basically dialysis involves a filter called a dialyzer that the patient's blood passes through. Potentially harmful molecules in the blood are diffused across the filter membrane and eliminated as waste. Dialysis replaces some of the function of normal kidneys, but not all. It is better to stay healthy and prevent the need for dialysis if possible. ...Read more
Cleans blood: Fluid is infused into the abdomen. The fluid is separated from the abdominal organs by the peritoneal membrane. Toxins that build up in the blood will diffuse through the membrane into the fluid. This fluid is then drained from belly and that is how toxins are removed from your body. ...Read moreSee 1 more doctor answer
Arterial Diversion: When an artery is connected to a vein, the vein walls thicken and become muscular (due to the new high arterial pressure). This makes finding the vein easier. More importantly, the large bore needles can be removed and pressure held, with clot forming in the muscular walls, to stop the bleeding. If the veins weren't muscular, putting the needle in and taking it out safely, aren't possible. ...Read moreSee 1 more doctor answer
