Dialysis (Definition)

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

How can a dialysis machine work?

How can  a dialysis machine work?

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

What is a dialysis machine based on?

Countercurrent flow: The dialysis machine is based on pumps that move blood through the artificial kidney (a filter) while making dialysate (a mixture of water and chemicals) to move the opposite direction through that filter. The blood and dialysate are separated by a semipermeable membrane in the filter. By moving in opposite directions, the waste products in the blood tend to go into the dialysate cleaning the body. ...Read more

How will they connect me to the dialysis machine?

Dialysis: I am presuming you are asking about hemodialysis. If you have a shunt created under your skin (arteriovenous shunt), you will be connected using needles. If you have an external, plastic shunt you will be connected without needles. Either way, connecting a patient to a dialysis machine requires great care and major attention to preventing infection. ...Read more

How can a dialysis machine work and why is it used?

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

Why do some people pass out while on a dialysis machine?

Why do some people pass out while on a dialysis machine?

Low Blood Pressure: Unfortunately, dialysis is an exchange of blood between the patient and the hemodialysis machine. At certain times, too much blood can be taken from a patient that leads to an acute drop in blood pressure. This decrease in blood pressure likely leads to some people passing out while on the hemo-dilaysis machine. ...Read more

How does a dialysis machine work and what is it used for?

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

What are the health risks of kidney dialysis machines?

What are the health risks of kidney dialysis machines?

Renal dialysis: machines do not dialyze the kidney. they remove toxins from the blood that the kidney normally does. So risks are; 1. You die without dialysis. I call this a bad risk. 2. You live longer and feel better. I call this a good risk. Other than that discuss you particular situation with your medical team. ...Read more
