What is dialysis, and how can it help?
Dialysis is one treatment for chronic kidney disease (CKD). The job of the kidneys is to filter our blood. But when they no longer work as they should, dialysis can help. Dialysis filters blood using a machine, or fluid, to do the work the kidneys usually do. It may be needed long term to treat end-stage renal disease (ESRD) or kidney failure.
What is dialysis and when is it necessary?
Dialysis is a treatment to replace the filtering function of the kidneys when they reach end stage renal disease. When kidney function goes below about 15%,kidney dialysis is necessary to clean the blood. Find out more about kidney failure and dialysis.

What organs help regulate blood pressure?
The waste and extra water make urine, which moves from the kidneys into the bladder. Your kidneys also help regulate your blood pressure.
Why do kidneys break down?
This is most often caused by conditions such as diabetes, high blood pressure, and obesity. These conditions make the kidneys work extra hard, and they start to break down. Most often, damage to the kidneys happens slowly over a period of time. When the kidneys do not work, the blood must be filtered another way.
Why do kidneys lose their ability to filter blood?
This is where the filtering takes place. Sometimes the nephrons start to lose their ability to filter blood. This is most often caused by conditions such as diabetes, high blood pressure, and obesity.
Where do you put a catheter for dialysis?
If dialysis needs to happen quickly, your provider may place a catheter (thin tube) into a vein in your neck, chest or leg for temporary access.

Why is dialysis important?
When your kidneys can’t perform these functions due to disease or injury, dialysis can help keep the body running as normally as possible. Without dialysis, salts and other waste products will accumulate in the blood, poison the body, and damage other organs.
When was dialysis first used?
Dialysis has been used since the 1940s to treat people with kidney problems.
What is PD in peritoneal dialysis?
Peritoneal dialysis. Peritoneal dialysis involves surgery to implant a peritoneal dialysis (PD) catheter into your abdomen. The catheter helps filter your blood through the peritoneum, a membrane in your abdomen. During treatment, a special fluid called dialysate flows into the peritoneum. The dialysate absorbs waste.
What is the function of kidneys when they fail?
This waste is sent to the bladder to be eliminated when you urinate. Dialysis performs the function of the kidneys if they’ve failed. According to the National Kidney Foundation, end-stage kidney failure occurs when the kidneys are performing at only 10 to 15 percent of their normal function. Dialysis is a treatment that filters and purifies ...
Where is hemodialysis performed?
Most hemodialysis treatments are performed at a hospital, doctor’s office, or dialysis center . The length of treatment depends on your body size, the amount of waste in your body, and the current state of your health.
What happens if you have long term dialysis?

How does a doctor do dialysis?
Before your first dialysis treatment, your doctor will surgically implant a tube or device to gain access to your bloodstream. This is typically a quick operation. You should be able to return home the same day.
How does dialysis work?
Dialysis works by filtering toxins, waste and fluid from your blood through a semipermeable membrane. The 2 types of dialysis, hemodialysis and peritoneal dialysis, use different methods to filter blood. With hemodialysis, the filtering membrane is called a dialyzer and is inside a dialysis machine. Your blood is circulated through the dialysis machine and cleaned before being returned to your body. With peritoneal dialysis, the filtering membrane is the natural lining of your peritoneum or abdomen and blood never leaves your body. Both types of dialysis also use a dialysate solution in the filtering process to remove unwanted substances from your bloodstream.
Why do people choose home dialysis?

Many people switch dialysis types to fit a changing lifestyle at some point during long-term treatment.
What is the end stage of kidney disease?
When a person with chronic kidney disease (CKD) reaches end stage renal disease (ESRD), also known as kidney failure or stage 5 kidney disease, the kidneys are no longer functioning to filter and clean the blood the way healthy kidneys normally would. Without treatment, life-threatening waste and toxins will build up in the body. At this point, dialysis treatment or a kidney transplant is needed to prolong life.
What is the treatment for kidney failure?
Dialysis is a treatment for kidney failure that rids your body of unwanted toxins, waste products and excess fluids by filtering your blood. When kidneys fail, your body may have difficulty cleaning your blood and keeping your system chemically balanced. Dialysis can take the place of some kidney function and, along with medication and proper care, help people live longer.
What happens when you connect to a hemodialysis machine?
Once you are connected to the machine via your hemodialysis access, blood flows into the machine, gets filtered and is returned to your body.

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.

Why is dialysis used?
It is used for two reasons (i) for introducing new molecules in a sample solution or (ii) to remove small molecules from a sample solution because it flows smoothly in any direction of the membrane. These two reasons make dialysis an extremely important chemical procedure for various applications and scientists prefer this procedure as well.
What is dialysis in medical terms?
Both procedures of dialysis chemical and biological are almost the same as it is the process of separation of small molecules from a sample solution into a dialysate buffer in the zone of chemistry while in the biological area the same process of separation is used to remove the toxins from the blood dialysate.
What is the pH of a dialysate buffer?
Ans: There are various processes used in the medical industry to treat diverse and unique diseases. To handle the molecules in a dialysate buffer, pH is essential for the stabilization and the separation of the molecular properties in the sample solutions. The range of typical pH rate in any dialysate or dialysis buffer is approximately around 4 to 5. There several types of buffers available but the most common dialysate buffer that is used and found in the biochemical solutions are as follow:
What is the chemical separation process used in dialysis?
The spontaneous and rapid type of dialysis chemical separation process. It is preferable by many scientists. Diffusion Dialysis uses AEM (Anion exchange membranes) and CEM (cation exchange membrane) which is dependent on the compounds and molecules that are to be separated.
What type of membrane is used in dialysis?
This chemical separation is an extremely rapid and spontaneous process of separating with the help of the semipermeable membrane, and the most types of membranes used in the process of dialysis are cellulose and synthetic polymer.
Why is electrodialysis important?
Electrodialysis is extremely important when it comes to removing molecules from aqueous solutions.
How does osmosis help dialysis?
Osmosis helps in the smooth functioning of dialysis as the fluid moves from high to low water concentration which makes it easy to pass through the semipermeable membrane or the dialysis tube.
What is the purpose of dialysis?
When the kidneys fail, dialysis can do their job of removing harmful substances and excess water from the body. This is done with the help of technology that makes use of the physical principles of diffusion, convection and osmotic pressure. The two main types of dialysis are hemodialysis and peritoneal dialysis.
How does hemodialysis work?
In hemodialysis, the blood is cleaned outside of the body (extracorporeal). The treatment usually takes place in a dialysis center (a clinical facility that specializes in dialysis). The procedure involves removing blood from a blood vessel, usually in a forearm, passing it through the dialysis device and then transporting it back into the body.
How does peritoneal dialysis work?
The lining of the abdominal cavity (the peritoneum) serves as a semipermeable membrane. The peritoneum is well-supplied with blood and covers the organs like the small and large intestines.
How does dialysis fluid flow?
These are made of semipermeable membranes and are surrounded by dialysis fluid. The dialysis fluid flows in the opposite direction to the blood. The technical term for this is counter-current flow. This is the best way to remove harmful substances, waste products and excess water from the blood and get rid of them together with the dialysis fluid.
What is the process of removing water from the blood?
Some dialysis methods use pressure to "push" water out of the blood. When the water is removed, any harmful substances dissolved in the water are removed at the same time. The technical term for this procedure is convection. Some hemodialysis devices can use convection as well as diffusion.
How long does it take for hemodialysis to work?
Hemodialysis usually takes around four to five hours. During this time, all the blood in the body is pumped through the dialysis device several times. Afterwards, the blood is clean enough. In Germany, hemodialysis is usually done three times a week.
How to explain diffusion?
In order to understand what diffusion is, it may help to picture a simple experiment from science class: An empty glass box is separated into two halves by a thin wall. The wall has fine pores (tiny holes) in it. A clear fluid is then poured into the right half, while a colored fluid is poured into the left half. What happens next? The colored particles in the left half will gradually move (diffuse) through the pores in the permeable wall into the clear fluid in the right half. Eventually, both fluids will be the same color. The number of colored particles in the water (the concentration) is then the same on both sides of the wall.
Why is it important to get enough dialysis?
It is important that you get enough dialysis. Studies have shown that getting the right amount of dialysis improves your overall health, makes you feel better, keeps you out of the hospital, and enables you to live longer. Your healthcare professional will give you a "dialysis prescription" to make sure you get the right amount of treatment. It depends on:
How does hemodialysis work?
During hemodialysis, your blood is pumped through soft tubes to a dialysis machine where it goes through a special filter called a dialyzer (also called an artificial kidney). As your blood is filtered, it is returned to your blood stream. Only a small amount of blood is out of your body at any time.
What is Kidney Failure?
Symptoms usually show up late in the process. Kidney failure is the end result of a typically gradual loss of kidney function. The most common causes of kidney failure are diabetes and high blood pressure. Kidney failure happens when:
What are the two treatments for kidney failure?
The two treatments for kidney failure are kidney transplantation and dialysis. Two different types of dialysis can be done - hemodialysis and peritoneal dialysis.
How to measure dialysis?
Your dialysis care team will monitor your treatment with monthly lab tests to measure the amount of dialysis you receive. This is called your "delivered dose of dialysis." The number that tells your delivered dose of dialysis is your Kt/V (pronounced "kay tee over vee"). The goal for your Kt/V number may vary depending on how often you have dialysis and on how much remaining kidney function you have left. For many hemodialysis patients who have three treatments weekly, Kt/V should be at least 1.2 for each treatment. For people receiving peritoneal dialysis, it should not be less than 1.7 per week.
What to do when you are on dialysis?
When you are on dialysis, it is important for you to: Come to every dialysis treatment and stay for the entire treatment. Learn what you can do to keep as much kidney function as you have left - and do it! Do your part to help manage the complications of kidney disease and kidney failure. Heart and blood vessel problems.
Is dialysis a kidney transplant?
Dialysis and kidney transplant are both treatments for kidney failure. You don't have to feel "locked in" to any one type of dialysis. There are advantages and disadvantages for each. If you wish to change your current treatment choice, speak to your healthcare professional.
