Dialysis Devices

Dialysis with a dialysis machine (also called blood washing or artificial kidney) is a method of detoxification and blood collection. The most common method is hemodialysis. If the kidney can no longer carry out its tasks, the external dialysis machine takes over part or all of the kidney. Peritoneal dialysis is rarely used to purify blood. If one or both kidneys are unable or no longer able to do their jobs properly (kidney failure), a dialysis machine must be used.

The kidneys have several jobs: They filter toxins from the blood and then excrete them with the urine produced by the kidneys. They also regulate the body's water and salt levels, for example by adjusting the amount of urine to the amount of fluid available. The kidneys can also regulate blood pressure over a long period of time and participate in metabolism and hormone production. Dialysis treatment cannot completely replace all functions of the kidneys. HH patients almost always need to take certain medications on a regular basis. These measures include antihypertensive therapy, drugs that lower blood phosphate levels, vitamins, and drugs that stimulate red blood cell production to prevent anemia.

Edema is common in patients with chronic renal failure. Excess water is removed from the blood by applying a pressure gradient (negative pressure on the dialysate side). This can control how much fluid is withdrawn from the blood, thereby mimicking the natural diuretic function of the kidneys. The extraction of fluid is limited by the fact that fluid (also applicable for toxins) in the body cannot diffuse into the blood as quickly as expected to make up for the fluid loss that threatens the life-threatening drop in blood pressure.

In addition, different tissues release fluids at different rates. For example, even if there is too much fluid in the body, the muscles cramp. These effects limit the amount of body fluids that can be withdrawn through dialysis, preventing patients from drinking freely. On the other hand, it is generally believed that a small amount of alcohol (elimination in 24 hours plus 500 ml) is stressful, as many patients continue to be very thirsty due to the build-up of urine in the body.
