There are numerous careers in dialysis, including technical and clinical paths. A nephrologist is a medical doctor who specializes in the kidneys and related conditions. Many registered nurses also specialize in kidney diseases and dialysis. Other positions include a variety of technical jobs, such as a dialysis technician or a hemodialysis technician. In this role, you perform similar responsibilities as a registered nurse but typically do not prescribe medical treatments. Your duties are to set up and calibrate dialysis equipment, administer anesthetics, and monitor dialysis by regulating anticoagulant and fluid levels. Technicians often report directly to a dialysis nurse at the clinic regarding the physical and emotional health of a patient.
