A semipermeable membrane is one that permits the passage of sure smaller molecules of such crystalloids as glucose and urea, however prevents passage of bigger molecules such because the colloidal plasma proteins and protoplasm. adj., adj dialyt´ic.
steady ambulatory peritoneal dialysis (CAPD) peritoneal dialysis involving the continual presence of dialysis answer within the peritoneal cavity; see dialogue at peritoneal dialysis.

dialysis

a course of by which small molecules might be separated from bigger ones utilizing a wonderful semipermeable membrane, e.g. cellophane or visking tubing, to comprise the bigger molecules, however which permits the smaller molecules to cross by way of into the water on the opposite aspect. The kidney machine, utilized in circumstances of kidney illness or failure, works on the dialysis precept, with arterial blood from the affected person’s arm being pumped by way of the dialysis tube then again right into a vein. Holes within the tubing enable small molecules similar to glucose, salt and urea to diffuse out into a shower of water, salts and glucose, whereas forsaking the proteins similar to albumin within the blood.

Dialysis

A technique of filtering and eradicating waste merchandise from the bloodstream. Two important varieties are hemodialysis and peritoneal dialysis.
