Question 1

how can  a dialysis machine work?

Accepted Answer

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.

Question 2

what is a dialysis machine based on?

Accepted Answer

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.

Question 3

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

Accepted Answer

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.

Question 4

what is the material of the dialysis tubing used in a dialysis machine?

Accepted Answer

Synthetic: It is made of Cellulose or cellophane.

Question 5

why would someone blood clog a dialysis machine?

Accepted Answer

See below: Dialysis involves the patients blood to run against the dialysis fluids in a artificial kidney or dialyser, 
both have seperate circuits and the blood ciruit may clot  and block the circuit.The reasons  are because it is running externally through a plastic. Many times a anticoagulant like Heparin is mixed with the blood artificially to prevent it clotting.

Question 6

what does it mean when a dialysis patient clogs the dialysis machine?

Accepted Answer

Kidney machine clog?: I am not sure what you are referring to by a dialysis patient's clogging of a kidney machine. Patients can have their dialyzer (d), the artificial kidney, during dialysis. This normally occurs when the patients are not getting enough Heparin during dialysis and their d's clot ending their use of that d. If that is not the answer you were looking for, ask the patient's nephrologist youyr question.

Question 7

how does kidney dialysis machine work?

Accepted Answer

Dialysis machine: The purpose of a dialysis machine (d) and the artificial kidney (a) used on it is to replace the function of the kidneys of a end stage renal disease kidney patient which do not work. The a filters the blood of the patient removing waste products and water the diseased kidneys of the patient cannot do. This prevents the patient dying of kidney failure.

Question 8

what is a dialysis machine actually filter out of the blood?

Accepted Answer

Excess "toxins": These include excess water, potassium, phosphate, and a host of other toxins called "uremic" toxins that your body normally gets rid of via the kidneys. However, the machines are not nearly as good as your own kidneys and some toxins do not get removed efficiently. Retention of these toxins causes the typical symptoms of kidney failure.

Question 9

why do we still die of organ failures? i thought modern medicine has all the machines that can replace organs. for example, dialysis for kidneys, no?

Accepted Answer

No: Modern medicine is awesome but the human body is incredible. We can mimic the kidney with dialysis but we can't quite get it right. Eventually we fail. We have not been able to do it nearly as well as the body itself. Our body is actually programed for death through apoptosis, or death of the individual cells. The only cell that live forever are cancer cells.

Question 10

how does a renal dialysis machine work?

Accepted Answer

Good question: Dialyzers are made of a polyurethane capsule within which hollow fibers or parallel membrane plates are suspended in dialysate (dialysis solution). The fibers or plates act as a semipermeable membrane across which blood and dialysate flow. By crossing this membrane, solutes and water move between a patient's intravascular compartment and the dialysis fluid contained within the dialyzer.
