Why Salt Solution Is Used For Dialysis

The dialysis mechanism used by the kidneys allows them to function effectively over a very wide range of conditions.

Why salt solution is used for dialysis. The final salt concentration in the protein solution is the weighted average of the salt concentration based on the volumes of the starting protein solution and the water. Dialysis concentrates and solutions the concentration of electrolytes besides potassium and the buffer substance closely resembles that which occurs naturally in the blood. The conductivity of the dialysis fluid is a parameter well suited for measuring the total concentration of salt. Because human extra cellular fluid ecf is 0 9 saline.

It takes longer periods and it removes around the same amount of total waste product salt. In the case of high starting salt concentration osmosis causes water to enter the sample faster than buffer salts within the sample are able to diffuse out resulting in the swelling of the sample within the dialysis sample compartment. As the volume of the solution in the dialysis tubing decreases the protein concentration increases. When your kidneys can t perform these functions due to disease or injury dialysis can help keep the body running as normally as possible.

These ions can move in an electric field giving the salt solution electrically conducting properties called conductivity. Dialysis fluid is prepared according to the individual patient s needs to help regulate their electrolyte and acid base balance and remove metabolic waste products. Dialysis fluid consists of a solution of inorganic salts that are dissociated in electrically charged ions. Normal saline solution is 0 9 saline as well it is compatible with every fluid in the body.

We can t use normal water less concentrated than blood or more concentrated solution than blood as it may result in process of osmosis. I am assuming that by salt solution you are referring to the 0 9 nacl saline solution used during the process of dialysis. Without dialysis salts and other waste products will. To date dialysates are prescribed to ensure that the solution contains an appropriate amount of sodium potassium and calcium which is specific to the patient s needs.

Moreover dialysates of specific composition can mitigate cardiovascular problems and metabolic acidosis. The reason is simple the solution is isotonic with the concentration of our blood. The salt in the dialysis tubing moves from high concentration to low concentration via passive diffusion. It is isotonic so it neither draws fluid.
