How is dialysis different from hemodialysis?

This is the same thing, hemodialysis is the purification of blood. there are two types, a fistula is formed on the arm / leg, needles are connected into the vein artery through which blood is drawn and returned, blood passes through the apparatus 6 times per hour. the procedure lasts 4 hours. the second option is peritoneal dialysis, a catheter is sewn into the abdominal cavity, a filter solution is poured, after a certain time it is drained and a clean one is poured. the first option has a severe restriction on fluid per day, the second does not, but the tube sticks out of the abdomen

If you have kidney problems and you are connected to a blood purifier, then go to hemodialysis. If you need to separate two colloidal solutions across a semi-permeable membrane, then you are doing dialysis. In the first case, there is filtration through a membrane, a filter, and in the second, the laws of osmosis and diffusion apply
