Research information related to dialysis and answer the following questions:What is the difference between hemodialysis and peritoneal dialysis?
Verified step by step guidance
1
Understand that dialysis is a medical process used to remove waste products and excess fluid from the blood when the kidneys are not functioning properly.
Recognize that there are two main types of dialysis: hemodialysis and peritoneal dialysis.
Hemodialysis involves filtering the blood through a machine outside the body. Blood is drawn out, cleaned by a dialyzer (artificial kidney), and then returned to the body.
Peritoneal dialysis uses the lining of the abdomen (peritoneum) as a natural filter. A special fluid is introduced into the abdominal cavity, which absorbs waste products and is then drained away.
Compare the two methods: Hemodialysis typically requires visits to a dialysis center, while peritoneal dialysis can often be done at home. Hemodialysis is usually performed several times a week, whereas peritoneal dialysis is done daily.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Dialysis
Dialysis is a medical procedure that removes waste products and excess fluid from the blood when the kidneys are unable to perform this function. It is essential for patients with kidney failure, as it helps maintain the body's chemical balance and prevents the buildup of harmful substances. There are two primary types of dialysis: hemodialysis and peritoneal dialysis.
Hemodialysis
Hemodialysis involves filtering the blood through a machine called a dialyzer, which acts as an artificial kidney. During the procedure, blood is drawn from the body, cleaned of toxins and excess fluids, and then returned to the bloodstream. This process typically occurs in a clinical setting and usually requires sessions several times a week, lasting about three to five hours each.
Peritoneal Dialysis
Peritoneal dialysis uses the lining of the abdominal cavity, known as the peritoneum, as a natural filter. A sterile solution is introduced into the abdomen through a catheter, allowing waste products and excess fluids to pass from the blood vessels in the peritoneum into the solution. This method can be performed at home and offers more flexibility, as it can be done continuously or in cycles throughout the day or night.
