Dialysis Technicians set up and operate hemodialysis machines to provide dialysis treatment for patients with kidney failure. Dialysis Technicians work on a daily basis with people whose kidneys no longer work properly or at all. These professionals are also sometimes called hemodialysis technicians or patient care technicians (PCTs).

Some of the daily work these technicians perform is removing wastes, salt, and extra water from patients' blood while keeping safe levels of certain chemicals. Dialysis patients generally use the machine for about four hours, three times a week. The technicians prepare patients for dialysis, monitor them and the machine during dialysis, and perform required procedures when dialysis is completed.

Dialysis technicians help patients feel comfortable during the procedure and keep the machine in good working condition. Most dialysis technicians work in hospitals under the supervision of a registered nurse. Others work in dialysis units run by private companies.
