What is dialysis

summary

Dialysis is a separation and purification technology that separates small molecules from biological macromolecules by the principle that small molecules diffuse into water through semi permeable membrane. Dialysis therapy is to make the body fluid components through the semipermeable membrane out of the body, generally can be divided into hemodialysis and peritoneal dialysis, then what is dialysis? Now let me share my experience with you.

What is dialysis

First, selective diffusion through the membrane. It can be used to separate solutes with different molecular weight. Substances with molecular weight lower than the threshold value can diffuse through the membrane, while substances with molecular weight higher than the threshold value are retained on the other side of the semi permeable membrane.

Second: clinical means that some waste in the blood is removed by semi permeable membrane. Hemodialysis is a safe, easy and widely used method of blood purification. Dialysis is the movement of solute from high concentration solution to low concentration through semipermeable membrane.

Third: hemodialysis includes the movement of solute and water, that is, the material exchange between blood and dialysate in dialyzer (artificial kidney) through semi permeable membrane contact and concentration gradient, so that the metabolic waste and excessive electrolyte in blood move to dialysate, and the calcium ion and base in dialysate move to blood.

matters needing attention

1. Smoking and drinking should be given up as soon as possible. Smoking and drinking contain a lot of carcinogens, which may lead to relapse at any time. 2. Diet can be matched with nutritional meals, moderate diet, can eat more fruits and vegetables, so for our body recovery can also play a great help.
