Dialysis Technicians set up and operate hemodialysis machines to provide dialysis treatment for patients with kidney failure. 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. Students wanting to become a Dialysis Technician will need at least a high school diploma. Various community colleges, vocational schools, and training centers across the country offer programs leading to certification. Courses in science and health are useful, as is volunteer or part-time work in a hospital. Mechanical ability is also important in this job.
