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 happens in process involving dialysis?
Dialysis is a procedure to remove waste products and excess fluid from the blood when the kidneys stop working properly. It often involves diverting blood to a machine to be cleaned. Normally, the kidneys filter the blood, removing harmful waste products and excess fluid and turning these into urine to be passed out of the body.
What are the working principles of dialysis?
- During the treatment of hemodialysis, the patient has to sit back or else lie back in a chair.
- Secondly, before starting as well as after treatment the weight, temperature and blood pressure of the patient is been measured.
- Two needles will be placed on the arm of the patient where the fistula or the graph is located.
Is dialysis very painful?

However, if you take care to follow your kidney diet and fluid restrictions these types of side effects can be avoided. Myth: Dialysis is a death sentence.
Is dialysis permanent or temporary?
In some cases of acute kidney failure, dialysis may only be needed for a short time until the kidneys get better. In chronic or end stage kidney failure, your kidneys do not get better and you will need dialysis for the rest of your life.
What happens when you take dialysis?
With hemodialysis, a machine removes blood from your body, filters it through a dialyzer (artificial kidney) and returns the cleaned blood to your body. This 3- to 5-hour process may take place in a hospital or a dialysis center three times a week. You can also do hemodialysis at home.
How long can you stay on dialysis?

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.

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 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?

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.

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.
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.
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 ...

What is the purpose of peritoneal dialysis?
Peritoneal dialysis uses the natural filtering ability of the peritoneum, the internal lining of the abdomen, to filter waste products from the blood.
Why does dialysis cause kidney failure?
The cause might be a chronic, or long-term condition, or an acute problem, such as an injury or a short-term illness that affects the kidneys. Dialysis prevents the waste products in the blood from reaching hazardous levels. It can also remove toxins or drugs from the blood in an emergency setting.

How often is hemodialysis done?
Hemodialysis is usually done three times a week, for 3 to 4 hours a day , depending on how well the kidneys work, and how much fluid weight they have gained between treatments. Hemodialysis can be done in a special dialysis center in a hospital or at home.
What is the function of the kidneys?
Healthy kidneys regulate the body’s levels of water and minerals and remove waste. The kidneys also secrete certain products that are important in metabolism, but dialysis cannot do this. A person who has lost 85 to 90 percent of their kidney function will be a likely candidate for dialysis.
What are the side effects of kidney dialysis?
People who depend on kidney dialysis may experience: Muscle cramps. Itchy skin, often worse before or after a procedure. Low blood pressure, particularly in people with diabetes. Sleep problems, sometimes due to itchiness, restless legs, or small breaks in breathing, known as apnea.
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 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.
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.
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.
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.
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 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:

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.
What is the process of separating ions and molecules from solids?
To define the scientific term, ‘dialysis’ is a process of separating molecules in particular solutions with the help of a membrane that is semipermeable known as a dialysis tube. It is a separation of dissolved ions and molecules from solid solutions. The separation of molecules takes place because there is a difference in the rate of diffusion of certain molecules in the solution.
What is Dialysis?
A kidney can filter 100-150 quarts of blood every day. If the kidneys are not functioning properly, waste starts accumulating in the blood. This results in coma and even death.
What is the function of dialysis?
Dialysis functions on the ultrafiltration of fluid through a semipermeable membrane and concept of the dissipation of solutes. Diffusion is a characteristic of materials in water that has the tendency to flow against a concentration gradient.
How is peritoneal dialysis done?
Peritoneal dialysis is done by surgically implanting a catheter in the stomach of the patient. A cleaning fluid (dialysate) is then circulated throughout the catheter that absorbs the waste materials from the blood vessels in the walls of the stomach. It is then drawn out and discarded.
What are the advantages of peritoneal dialysis?
Advantages of Dialysis. Dialysis can be carried out even at home. Peritoneal dialysis is a comfortable method of dialysis that is easy to use. The equipment used in peritoneal dialysis is less bulky and easy to carry along with the patient. Unlike peritoneal dialysis, hemodialysis is not be carried out every day.
How does dialysis help with blood pressure?
To cure this, the patient is subjected to dialysis. Dialysis maintains the body balance in the following ways: 1 It controls blood pressure. 2 It removes excess water and metabolic wastes from the body. 3 Prevents chemicals such as potassium, bicarbonate and sodium from reaching hazardous levels.
Why is dialysis needed?
Dialysis is required when the kidney is unable to filter waste from the blood. This may be due to certain acute and chronic diseases, exposure to toxic pollutants, or certain medications.
How does hemodialysis work?
In hemodialysis, blood is pumped out of the body, filtered through a machine and returned to the body through the tubes that connect the patient to the machine. On the contrary, in peritoneal dialysis, a catheter is implanted in the patient’s stomach through which the dialysate is circulated. This dialysate absorbs all the waste from the body.
What is the purpose of peritoneal dialysis?
Peritoneal dialysis – Pumps dialysis fluid into abdominal space to draw out waste products from the blood.

What is dialysis treatment?
It’s a treatment that takes over your kidney functions if those organs stop doing their job. There are two types of dialysis: Hemodialysis: Your blood is put through a filter outside your body, cleaned, and then returned to you. This is done either at a dialysis facility or at home.
How does hemodialysis work?
This works like a kidney and filters out extra salt, waste, and fluid. Your cleaned blood is sent back into your body through the second needle in your arm. Or, if there’s a catheter, blood comes out of one port and then is returned via a second port. You can have hemodialysis in a hospital, a dialysis treatment center, or at home.
