Knowing How to Work Hemodialysis and Peritoneal Dialysis - How hemodialysis work
Dialysis is the process of cleaning wastes from the blood as a substitute for kidney function.

Without dialysis, all patients will die of kidney failure due to accumulation of toxins in the bloodstream.

Currently there are two types of dialysis that use the peritoneal dialysis and hemodialysis.


Hemodialysis uses a machine known as the hemodialyzer which acts as an artificial kidney.

Hemodialyzer to blood should be screened, so doctors will install access ports on the vein in the arm or leg.

If a patient does not have a large enough vein, the doctor will make a greater access, known as fistula, in which the arteries connected to the veins.

However, if the size of the blood vessels is still not right, the doctor can use plastic tubing to combine the arteries and veins.

The final choice is for access by inserting a catheter into the neck veins.

Once the patient is connected to a dialysis machine via port access, either through one or two needles attached to the port, the tube will be attached to the needle, and the blood leaves the body through the needle and into the hemodialyzer.

When the blood reaches the dialyzer, the machine will eliminate waste and fluids from the blood.

Further blood is returned to the body through a second needle, or in ports located in the fistula or through a catheter.

Dialysis machine will clean up most of the blood. The process can take between 3 to 6 hours, and only 200 mL of blood outside the body at one time.

Time required in the dialysis process will depend on the current renal function, body weight and height, as well as the amount of fluid that accumulates in between treatments.

After the procedure is completed, the needle will be removed and the patient allowed to go home.

peritoneal Dialysis

Peritoneal dialysis involves cleansing the kidneys in the body, rather than clean up the blood as in hemodialysis.

The doctor will perform a surgical procedure to place a plastic catheter into the stomach, to be used as an access port.

Peritoneal cavity, which is located in the abdominal area, filled with dialysate. Dialysate fluid that is used to help purify the blood by pulling waste out of the blood.

Peritoneum cavity acts as a membrane, in which the blood flowed and cleaned by the dialysate, which is then returned to the body. This process usually takes between 4 and 6 hours a day.

Once completed, the solution of fluid (fluid solution) would be drained from the abdomen. The stomach drying process takes about 30 to 40 minutes.

Once the process is complete, the catheter will be removed and the patient can resume their regular activities.
