How is dialysis done

There are two methods of dialysis. One is when kidney function is relatively good and the condition is not very serious. It is a temporary device that dialyzes blood from the femoral artery and then returns the dialysate through the vein. Another situation is that the renal function has become relatively weakened to a serious degree and requires maintenance hemodialysis. In this case, dialysis usually involves a blood fistula in the arm, followed by the same steps.

The kidneys filter the blood, removing waste products. If the kidneys fail, waste products accumulate in the body and eventually become poisonous. Renal dialysis is also called artificial kidney, and some people call it hemodialysis (abbreviated as hemodialysis) or dialysis. Hemodialysis is called Hemodialysis in English. Hemo refers to blood and dialysis comes from Greek, which means the release of certain substances. It means dialysis in English. It is a type of blood purification technology. Most of the 500,000 patients worldwide who rely on dialysis to sustain their lives are on hemodialysis. Hemodialysis is of certain significance in alleviating patients' symptoms and prolonging their survival.

Hemodialysis

Hemodialysis, abbreviated as hemodialysis, is also commonly known as artificial kidney or dialysis. It is a type of blood purification technology. It uses the principle of semipermeable membrane to remove various harmful and redundant metabolic wastes and excess electrolytes in the fluid out of the body through diffusion, so as to purify the blood and correct the balance of water, electrolyte and acid-base.

Peritoneal dialysis

Peritoneal dialysis uses the peritoneum as a semi-permeable membrane and gravity to infuse the prepared dialysate into the patient's peritoneal cavity through a catheter. In this way, there is a concentration gradient difference of solutes on both sides of the peritoneum, and the solutes on the high-concentration side move to the low-concentration side (diffusion effect); water moves from the hypotonic side to the hypertonic side (osmotic effect). The peritoneal dialysis fluid is continuously replaced to remove metabolic products and toxic substances from the body and correct water and electrolyte imbalances.

Instruments: Because renal dialysis relies on instruments for extracorporeal blood circulation, there is a certain risk to the patient, so the grade and safety factor of the instrument are very critical. Some large hospitals mostly use imported carbonation machines (such as the Swedish brand Campbell) and are equipped with full-time maintenance engineers. Some hospitals use acetic acid machines, which are obsolete models and can easily cause headaches and hypoxia in patients.
