How does a dialysis machine work?
It also monitors the blood flow, temperature and proper mixture of the dialysate. If any of these go out of range, the machine lets us know by sounding an alarm, blinking lights and shutting down blood or dialysate flow. It also lets us know if your blood pressure is too low or high.
How do I start a dialysis center?
Apply due diligence to identifying license- and permit-granting authorities required by your state and city for the operation of a dialysis center. Rent a facility. Your dialysis center can occupy any building that can be remodeled into a patient treatment center.
How does dialysate enter the dialyzer?
Fresh dialysate from the machine enters your dialyzer throughout your treatment. Impurities are filtered out of your blood into the dialysate. Dialysate containing unwanted waste products and excess electrolytes leave the dialyzer and are washed down the drain.
What is the solution in a dialysis machine?
The other solution is bicarbonate or bicarb, which is like baking soda. Both are mixed inside the machine with purified water. While you are dialyzing, dialysate and your blood flow through the dialyzer (but they never touch).
What is a dialysis machine?
The dialysis machine mixes and monitors the dialysate. Dialysate is the fluid that helps remove the unwanted waste products from your blood. It also helps get your electrolytes and minerals to their proper levels in your body. The machine also monitors the flow of your blood while it is outside of your body. You may hear an alarm go off from time to time. This is how the machine lets us know that something needs to be checked.
What happens to the blood tubing during dialysis?
One problem that may occur during dialysis is that air gets into the blood tubing. To prevent this from happening, blood tubings have two air traps built into them. One trap is before the dialyzer and the other is after it. These traps catch any air that may get into the system.
What is dialysate made of?
The machine mixes the dialysate, which is made up of an acidified solution, bicarbonate and purified water. The acidified solution contains electrolytes and minerals. You may hear it referred to as “acid.”. The other solution is bicarbonate or bicarb, which is like baking soda. Both are mixed inside the machine with purified water.
Does dialysate flow through a dialyzer?
While you are dialyzing, dialysate and your blood flow through the dialyzer (but they never touch). Fresh dialysate from the machine enters your dialyzer throughout your treatment. Impurities are filtered out of your blood into the dialysate.
How does dialysis machines actually work?
To help you understand even better, here’s a general step-by-step explanation of how a typical dialysis machine works.
Why do people need dialysis machines?
In simple words, the role of dialysis machines is to try to mimic the functions of a healthy human kidney. This is necessary as a renal patient’s kidneys cannot filter out waste products from the blood as needed anymore.

What is the difference between renal and dialysate?
A renal patient’s blood contains a high concentration of toxins, while dialysate contains a low concentration of toxins. Because of this difference, diffusion takes place wherein waste and excess fluids move from the blood across into the dialysate, creating an equal amount on both fluids.
What is the membrane that allows blood to flow through a dialysis tubing?
The blood flows through a dialysis tubing, a semipermeable membrane that contains pores large enough to allow diffusion—the movement of a substance from an area of high concentration to an area of low concentration.
What is dialysate pumped out of?
The used dialysate (now containing waste products removed from the blood) is pumped out of the machine and discarded. While the blood goes through another arterial pressure monitor and air trap to ensure that it’s safe to return into the patient’s body.
How does a pump and an arterial pressure monitor work?
A pump and an arterial pressure monitor work hand-in-hand in keeping the blood flow at a right rate. The blood enters the dialyzer. A dialysate enters the dialyzer. Also called a dialysis solution, this is a fluid made up of water, electrolytes, and salts.
How long does it take to learn hemodialysis?
Hemodialysis or blood dialysis can be performed in a center where you come for dialysis three times weekly and dialysis treatments are generally about four hours long. Alternatively, you can be taught to do hemodialysis at home. This is known as home hemodialysis and this may take 3 or 4 weeks to learn. Home hemodialysis is generally done five or six days per week for shorter amounts of time. Home hemodialysis can be done in short daily sessions, overnight “nocturnal” sessions or every other day longer sessions. Hemodialysis requires that you have a fistula created as a blood access in your arm. This must be created several months before you start dialysis therapy.
Why do you need dialysis?
The most common reason to start dialysis therapy is because you are retaining fluid that is causing edema or you are experiencing difficulty with fluid accumulation in your lungs. If this cannot be treated with medication, then dialysis may be the only option. If you develop fluid around your heart or inflammation around the heart (known as pericarditis) then dialysis may also be needed. Weight loss with advanced Stage 5 CKD is a very poor prognostic sign and may indicate the need for dialysis.
How to know if you have advanced stage 5 CKD?
Common symptoms of advanced Stage 5 CKD are nausea, vomiting (especially in the early mornings), itching, loss of energy, and loss of appetite. Many of these symptoms can be relieved with dialysis therapy. The accumulation of toxic wastes in your blood such as potassium and acid can sometimes require the initiation of dialysis therapy. The nephrologist and you must review all of your symptoms, know your underlying medical status and then discuss with you the things that dialysis may help and the things that may be complicated by starting dialysis therapy. Two major areas of concern are your ability to travel and your social support at home. Those patients who have little social and family support at home do not do well on dialysis therapy. If you are unable to easily travel to a dialysis center, home dialysis may be an easier consideration for some patients.
What is the stage of kidney failure?
There are five Stages of CKD, with the most advanced being Stage 5, with an estimated glomerular filtration rate (eGFR) of less than 15. It is generally patients with Stage 5 CKD that are considered candidates to start dialysis therapy or be considered for kidney transplantation. Once dialysis or transplantation is felt to be necessary, this is called End Stage Renal Disease (ESRD). If your eGFR is less than 20, you can be evaluated and placed on the waiting list for a kidney transplant. A transplant center will put you on the list if they deem you eligible for transplantation. Transplantation can be performed prior to the need for dialysis, if kidney failure is progressing slowly enough so that your symptoms can be controlled with diet and medication.
Is dialysis based on a specific number?
It may involve others, such as your family, your minister, or your friends, but the final decision is made with input from you and your physician. It is not based on any particular laboratory test or any specific number. It is based on whether your symptoms are consistent with advanced chronic kidney disease (CKD) and whether dialysis has the potential to relieve those symptoms.
Does Medicare cover dialysis?
Patients frequently have many financial questions about dialysis therapy. Medicare pays for 80 percent of dialysis therapy in those individuals who are eligible for Medicare or for Social Security Disability. If you are not currently on Medicare, there may be a three month waiting period to be eligible for Medicare coverage. If you start home dialysis therapy, either peritoneal dialysis or home hemodialysis, Medicare coverage can be immediate. More information is available at the Medicare web site. Pre-dialysis education is also covered under Medicare. You should discuss this with your nephrologist. For more information, visit the dialysis section of our A to Z Health Guide here.
Where is dialysis done?
Dialysis can be done in a hospital, in a dialysis unit that is not part of a hospital, or at home. You and your doctor will decide which place is best, based on your medical condition and your wishes.
When is dialysis needed?
You need dialysis when you develop end stage kidney failure --usually by the time you lose about 85 to 90 percent of your kidney function and have a GFR of <15. Click here to learn more about the stages of Chronic Kidney Disease and GFR.
Are there different types of dialysis?
Yes, there are two types of dialysis --hemodialysis and peritoneal dialysis.
What is peritoneal dialysis and how does it work?
In this type of dialysis, your blood is cleaned inside your body. The doctor will do surgery to place a plastic tube called a catheter into your abdomen (belly) to make an access. During the treatment, your abdominal area (called the peritoneal cavity) is slowly filled with dialysate through the catheter. The blood stays in the arteries and veins that line your peritoneal cavity. Extra fluid and waste products are drawn out of your blood and into the dialysate. There are two major kinds of peritoneal dialysis.
How long has dialysis been available?
Hemodialysis and peritoneal dialysis have been done since the mid 1940's. Dialysis, as a regular treatment, was begun in 1960 and is now a standard treatment all around the world. CAPD began in 1976. Thousands of patients have been helped by these treatments.
How long can you live on dialysis?
Average life expectancy on dialysis is 5-10 years, however, many patients have lived well on dialysis for 20 or even 30 years. Talk to your healthcare team about how to take care of yourself and stay healthy on dialysis.
Is dialysis expensive?
Yes. Dialysis costs a lot of money. However, the federal government pays 80 percent of all dialysis costs for most patients. Private health insurance or state Medicaid programs also help with the costs.
What does a dialysis machine do?
Two tubes are connected via your hemodialysis access. Blood flows from your body into the machine through 1 of the tubes.
How is my dialysis treatment monitored?
During your dialysis session, detailed information will show on the machine’s monitoring screen. Every function will be monitored, including the pump speed, blood pressure and dialysate temperature. Every check is designed to make sure your dialysis session is safe and effective.
What does a dialyzer (artificial kidney) do?
A dialyzer is the part in the hemodialysis machine where your blood gets filtered.
How does hemodialysis work?
How Does a Hemodialysis Machine Work? 1 Two tubes are connected via your hemodialysis access. Blood flows from your body into the machine through 1 of the tubes. 2 If your doctor prescribes blood thinner as part of your treatment, it will be added to keep your blood from clotting while it’s in the machine. 3 A pressure monitor and pump work together to keep the flow at the right rate. 4 Your blood enters the dialyzer, where it is filtered. 5 Dialysate solution enters the dialyzer. It draws the waste out of your blood. 6 Used dialysate solution is pumped out of the machine and discarded. 7 Your blood goes through another pressure monitor and an air trap to make sure it’s safe to go back into your body. 8 Your cleaned blood returns to your body through the second tube attached to your access site.
What does an alert mean on a dialysis machine?
An alert will sound if anything needs attention. An alert may simply mean the machine needs to be checked or something needs to be adjusted. If you’re doing home hemodialysis, you’ll be trained on what to do for any alert you might hear as part of your overall dialysis and safety training. You can also call your nurse 24/7 if you have questions or need assistance. If you receive in-center hemodialysis, your care team will monitor the machine throughout the process and make any adjustments necessary.
What happens if the power goes off on a dialysis machine?
If the power goes off while your cycler is working, it will automatically close all the lines. The machine will store the information about your session using a backup battery. If the power comes back on soon, that stored information lets the machine continue the session. If not, it’s best to call your home dialysis nurse about what to do next—support is available 24/7 if you ever have questions or concerns.
What is the purpose of dialysate solution?
Dialysate solution enters the dialyzer. It draws the waste out of your blood.
What is the first prerequisite for a dialysis clinic?
The people who will patronize your clinic are literally putting their lives in your hands, so the first prerequisite for clinic launch is a willingness to make patient needs your first priority.
What is the first decision you need to make when buying a dialysis clinic?

How many patients can you have in a dialysis clinic?
According to some estimates, the breakeven patient load for a dialysis clinic startup is 18 to 24 dialysis patients. If you aren't confident that your clinic can attract at least a few dozen patients fairly quickly, it's time to go back to the drawing board.
Can a dialysis clinic talk to you?
However, a fellow entrepreneur who has started a dialysis clinic in a different city will be much more likely to talk with you, after they realize you reside far away from them and won't be stealing their local customers. In that case, the business owner may be more than happy to discuss the industry with you. It can take a while to find an entrepreneur who is willing to talk, but it's well worth the effort.
