Question

What is dialysis? Under what condition is it carried out?

Answer 1

The kidney is one of two abdominal organs. The kidneys filter waste and excess water from the circulation (through urine) and aid in the balance of substances in the body (such as sodium, potassium, and calcium). The kidneys also produce hormones that assist regulate blood pressure and encourage the production of red blood cells in the bone marrow.

Complete answer:
Dialysis is a medical procedure that removes excess water, solutes, and toxins from the blood in patients whose kidneys are unable to do so naturally. Renal replacement treatment is the term for this. In 1943, the first successful dialysis procedure was done.
When there is a sudden fast loss of kidney function, known as acute kidney injury (formerly known as acute renal failure), or when a progressive reduction in kidney function, known as chronic kidney disease, reaches stage 5, dialysis may be required. When the glomerular filtration rate is 10–15 percent of normal, the creatinine clearance is less than 10 mL per minute, and uremia is present, it is considered stage 5 chronic renal failure.
Dialysis maintains your body in equilibrium when your kidneys fail by:
1. Eliminating waste, salt, and excess water from the body to prevent them from accumulating.
2. Keeping certain molecules in your blood at an acceptable level, such as potassium, sodium, and bicarbonate.
3. Assisting with blood pressure regulation.
A dialysis machine is an artificial kidney. The dialysis machine is used when both kidneys cease to function. The blood is drawn from the patient's radial artery and sent through the machine, which removes the urea and excess salts before returning the purified blood to a vein in the same arm. Dialysis must be performed for roughly 12 hours twice a week if the kidneys are permanently damaged.

Note:
An artificial kidney (hemodialyzer) is used to remove waste, excess chemicals, and fluid from your blood during hemodialysis. The doctor will need to make an access (entry) into your blood arteries to get your blood into the artificial kidney. This is accomplished by simple surgery on your arm or leg.
