Dialysis

Your doctor will tell you when your kidneys have failed. They monitor those things very carefully when you have damaged or diseased kidneys. If you think your kidneys are not working properly, you need to see a doctor immediately to see if they can repair the damage or reverse it.

Yes, chloride ions can diffuse out of a dialysis bag if the dialysis membrane is permeable to them and if there is a concentration gradient. Dialysis works by allowing smaller molecules and ions to pass through the membrane while retaining larger molecules. If the concentration of chloride outside the bag is lower than inside, chloride will move out of the bag to equalize the concentrations.

Renal dialysis is done for someone when their kidney function is so low, that toxins build up in the blood and literally poison the person. Dialysis takes over the function of the kidneys. The treatment is normally done on an out patient schedule - 3 times a week, anywhere from 3 or 4 hours to 6 hours per day. Depending on other medical conditions the person is suffering with; following the treatment they either feel great or completely worn out.

For some people dialysis is a stop gap procedure, until they get a match for a kidney transplant. For others - whose kidney failure is part of a system wide organ failure - it is an attempt to keep them alive and as well as can be expected, for the shape they are in.

diffusion

Dialysis is warranted depending upon the level of kidney function. A blood test that reflects the level of creatine (a waste product of cellular functions) in the blood. If the level of Creatine is too high, it means that the kidneys have either had a pathological partial or full failure and waste products that are usually 'filtered' out of the blood into the urine (from the kidneys to the bladder before it is expelled). Dialysis is a treatment that takes the patient's blood and pumps it through very fine filters to remove the cellular waste products from the blood and therefore prevent a general shutdown of the kidneys and later the whole body.

Hemodialysis

I don't know unless you give more details!

Dialysis Tubing is a type of semi or partially permeable membrane tubing made from regenerated cellulose or cellophane. It is used for diffusion, or more accurately osmosis. It allows the passage of small molecules but not larger ones. It is used in clinical circumstances to ensure a filtered flow of molecules, preventing the flow of larger solute molecules. Small molecules can be 'washed' out of a solution which is pumped through the tubing into a solvent, usually water, which surrounds it and in which they can be flushed away.

dialysis refers to stripping the blood of toxins that the kidneys cannot do themselves cause they either work poorly or have some other issue... the blood when it is cleaner is infused back into the body.

No; the sucrose molecule (as a disaccharide) is too large to pass through by passive diffusion. Glucose, on the other hand, (a monosaccharide) is able to permeate the dialysis tubing. In the body, glucose/sucrose is transmitted across membranes though the use of active/facilitated diffusion.

Dialysis is the process of replacing kidney function. Diffusion is just the natural tendency of things to move from higher concentration to lower concentration. Example: You have two identical rooms next to each other and one is filled with smoke and the other is not. Now imagine there is a door that conects these two rooms together. What would happen if you opened the door? The smoke would move towards the smokeless room and clean air would rush into the smoke filled room until there is equal amount of smoke in both rooms. How does this apply to dialysis? The artificial kidney has two chambers one is for the blood (this includes the inside of the membrane) and the other is for dialysate (cleansing fluid). The blood flows through the membrane in one direction and the dialysate flows through the artificial kidney in the opposite direction. The membrane, wich is basically a large bundle of small tubes with a bunch of tiny holes all along the outside of it, (holes that are too small to let blood vessels escape, but will allow waste particles to escape) allows the cleansing of the blood by diffusion. Example, if the potassium in your blood is at 5.5 and the potassium in the dialysate is 2.0 what do you think will happen to the potassium level in the blood? Remember the smoke filled room? Any dialysis professional would say that there is way more to it than that, and they are right, but I have tried to put it in a nutshell and in layman's terms.

I recommend you ask others that know Dialysis Technician training. It would help much more than asking people that doesn't know. Many people might not know much about dialysis technician training.

Willem Kolff Invented the kidney dialysis machine (1944)

in teh UK, they make them go to china and buy kidneys, otherwise if you have renal disease and on dialysis and turn 65, you go to morgue.

Urea passes through the dialysis tubing into the dialysis fluid due to the process of diffusion, where molecules move from an area of higher concentration to an area of lower concentration. The dialysis tubing is semi-permeable, allowing small molecules like urea to cross while retaining larger molecules and cells. As urea accumulates in the blood and reaches a higher concentration than in the dialysis fluid, it diffuses out to achieve equilibrium. This process helps remove waste products from the blood in dialysis treatments.

no

As starch is something which the body wishes to hold onto, the nephrons in the kidney have small pores which stop larger particles like starch and also blood cells from escaping, while water and salts do. For this reason, the dialysis machine works in the same way.

According to the National Kidney Foundation, 26 million American adults have chronic kidney disease; about 50,000 of those patients end up receiving renal replacement therapy, whether it be dialysis or (many fewer) a kidney transplant. As kidney disease progesses, the body's ability to process/eliminate wastes as well as regulate a number of metabolic processes diminishes. Common risk factors for the development of such kidney insufficiency include long-standing/poorly-controlled hypertension, diabetes mellitus, and poly-cystic kidney disease.

There are two methods of dialysis in use: hemodialysis (blood dialysis) and peritoneal dialysis (dialysis in the abdominal cavity).

In hemodialysis, the dialysis membrane is made up of cellophane or other synthetic material that assists in the removal of impurities from the blood by their passage through these semipermeable membranes in a fluid bath.

In peritoneal dialysis, the surface area of the peritoneum acts as the membrane. Dialysis fluid is introduced into the peritoneal cavity and then periodically removed along with the waste products. This procedure may be done at intervals throughout the day or during the night.

in the treatment of patients suffering from poisoning or overdose, in order to quickly remove drugs from the bloodstream. Its most prevalent application, however, is for patients with temporary or permanent kidney failure

It is located at where the patient's blood is drawn in.

The kidney's perform 6 important functions:

1. Fluid and electrolyte balance through filtration, re-absorption and secretion. An overabundance of either can be fatal.

2. Removal of waste and excess water. This is arguably the most important function of the kidney. When a kidney does not function some or all of the fluids that go into the body are not expelled and go into the blood stream. This causes strain on the heart because it has a greater volume of fluid to pump which can lead to the muscle to become weakened or stop all together if the excess fluid volume is great eighth kidneys also remove blood urea nitrogen (end product of protein metabolism), creatinine (waste product of muscle metabolism) and drugs that are metabolized by the kidney and excreted in the urine.

3. Maintenance of acid/base balance in the blood stream to keep the pH balance between 7.35 and 7.45.

4. Production of erythropoetin, which stimulates the bone marrow to produce red blood cells.

5.controls blood pressure by regulating sodium and water in the body as well as producing the hormone renin which also aids in controlling blood pressure.

6. The conversion of vitamin D to active form to keep bones strong.

Dialysis and medications and diet can help keep the body close to it's equilibrium. In the case of hemodialysis, the blood cycles through a machine and passes though a filter called a dialyzer that removes excess "toxins" (excess electrolytes, chemicals and waste) and water in the blood stream. Along with the filter, the blood is cleaned with an acid/base solution of sodium bicarbonate and potassium acid that keeps pH in range.
To reproduce the erythropoetin and active vitamin D most patients on dialysis are prescribed the Epogen (stimulates bone marrow to produce red blood cells) and Hecterol (active vitamin D supplement The removal of excess water during the dialysis process aids in lowering blood pressure but many patients are prescribed blood pressure lowering medications. Diet regulation is recommended because dialysis can only remove so many toxins in the body and an excess of something like potassium is easily fatal in people with kidney failure.

Disequalibrium syndrome is a rare condition caused by the rapid removal of urea during hemodialysis. This rapid removal causes a shift in plasma osmotic pressure leading to cerebral edema and the resulting signs and symptoms of increased intracranial pressure: hypertension, nausea, vomiting, confusion, etc...
