How To Set Up A Dialysis Machine
Hi when I set up coffee machines I sometimes sip/taste 30 cups of coffee in a short time. Could this damage my kidneys? I eat as little as possible salt n sugar. Exercise regularly. Low processed foods so none to little sodium.
Taste and spit:
I trust that you do not drink 30 cups of coffee, just taste the coffee from 30 different cups. Taking up to 4 cups of coffee/day will not do harm and may be good for you.
It is good that you exercise.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more
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
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

Flow rate?: Blood may clot in the dialysis circuit if it isn't flowing fast enough. Blood has a tendency to clot if it 'stands still' or slows down enough. The quality of the 'access' (i.e., usually a fistula) may be a factor here. Additionally, the position of the needles within the fistula may also impact the flow rate. And needless to say, a crimped line will result in clotting if not corrected. Lgromkomd. ...Read more
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. ...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
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
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
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
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
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. ...Read more
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
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. ...Read more
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?
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. ...Read more
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. ...Read more
Dialysis: By removing potentially toxic waste and excess water. In simple terms, it cleanses the blood in a similar fashion to the kidney, but it is not nearly as good as a single, well functioning kidney. ...Read more
My dad has to have a kidney removed. How long will he need to use the dialysis machine after the operation?
??: This needs to be discussed with your doctor/surgeon. Why is he having kidney surgery? He may not need dialysis at all. It depends on his health problems. I can't answer this without a lot more information. ...Read more
Filters: Kidneys filters blood, They basically have all the body's blood pass through them and they have specialized filters that take salts, toxins, drug and drug metabolites out. When they are not working dialysis machine's try to take over that function. Medicine has advanced a lot, and they are better than before, but still are not as efficient as the natural human kidney. ...Read more
