Core Responsibilities

Primary Functions

Prepare, calibrate, and operate hemodialysis and related renal replacement equipment (e.g., high-flux and low-flux dialyzers, blood tubing sets, dialysis chairs, and monitors) according to physician prescription and facility protocols to ensure safe and effective treatments.
Set up dialysis machines and reverse osmosis (RO) water treatment systems each shift, perform routine water quality checks (conductivity, total chlorine, bacterial counts, endotoxin testing) and document results to meet regulatory and infection control standards.
Verify physician orders, dialysis prescriptions, and patient-specific parameters (ultrafiltration goal, dialysate composition, treatment duration) prior to initiating therapy and adjust settings under RN/physician guidance when clinically indicated.
Perform pre-, intra-, and post-dialysis patient assessments: obtain and document baseline vitals, weight, and symptom review; monitor patients continuously during treatment for hemodynamic instability, cramping, hypotension, and other complications.
Initiate and terminate dialysis treatments safely, performing venous and arterial line connections and disconnections in accordance with facility policy and competency training; assist with or perform vascular access cannulation where state regulations and certification permit.
Monitor dialysis machine alarms, troubleshoot circuit and machine issues (air detector, pressure alarms, blood leak detector), and perform first-line corrective actions to rapidly restore therapy and protect patient safety.
Recognize and respond to acute dialysis emergencies (severe hypotension, arrhythmia, air embolism, bleeding), provide immediate supportive measures, summon RN/physician assistance, and assist with emergency procedures per unit protocols.
Deliver strict infection control and universal precautions: perform vascular access site care, maintain aseptic technique during maintenance and dressing changes, clean and disinfect machines and surfaces between patients, and adhere to PPE and sharps disposal protocols.
Document all aspects of dialysis treatments in the electronic medical record (EMR) including vitals, machine settings, UF removed, medications administered or accessed by RN, complications, and discharge instructions to maintain accurate clinical and legal records.
Collaborate with the interdisciplinary renal care team (nephrologists, RNs, dietitians, social workers, pharmacists) to escalate clinical concerns, support care plans, and communicate treatment changes or patient education needs.
Administer selected therapies under supervision and within scope (e.g., saline flushes, heparin bolus per protocol, EPO/supplement assistance as permitted) and accurately record all administered medications or interventions.
Collect, label, and process laboratory specimens (pre- and post-dialysis labs, blood cultures) per policy, ensure proper chain-of-custody, and coordinate transport to the laboratory.
Maintain and track dialysis supplies and inventory (dialyzers, tubing, concentrates, needles, gowns) to ensure uninterrupted service; report shortages and assist with ordering and stocking.
Perform routine maintenance and basic repairs on dialysis machines and water treatment systems, coordinate preventative maintenance with biomedical engineering or vendor service, and tag out equipment when necessary.
Provide patient-centered education: explain aspects of dialysis treatments, vascular access care, diet/fluid restrictions, and troubleshooting for home dialysis patients in clear, compassionate language suitable to patient literacy and cultural needs.
Participate in unit-based quality assurance and improvement initiatives: monitor infection rates, access-related complications, machine downtime, and help implement corrective actions and best practices to meet regulatory requirements.
Adhere to HIPAA, OSHA, and state regulatory requirements in all clinical and documentation activities, complete required incident reports, and participate in root-cause analyses when indicated.
Support and train new dialysis technicians and students by demonstrating competent procedures, conducting supervised skills checks, and providing constructive feedback to uphold unit standards.
Provide safe patient transport and positioning for dialysis within the unit or to/from procedure areas, ensuring patient stability and dignity throughout the process.
Assist with home dialysis programs by instructing patients and caregivers on machine setup, line care, infection prevention, and documentation required for safe self-care at home.
Participate in on-call rotation or flexible scheduling (evenings, weekends, nights) as required by facility needs, maintaining readiness to respond to urgent dialysis needs in inpatient or outpatient settings.
Maintain professional development through continuing education, competency validations, and required certifications to ensure current best practices in dialysis care.

Secondary Functions

Contribute to data collection for dialysis quality metrics (e.g., Kt/V, URR, access infection rates) and support nursing leadership with operational reports.
Assist in the development and revision of unit policies and procedure manuals related to dialysis operations and infection control.
Support ad-hoc patient outreach and engagement efforts (e.g., missed-appointment follow-ups, pre-dialysis patient calls) to improve adherence and outcomes.
Participate in cross-functional committees focused on patient safety, environmental cleaning, and equipment lifecycle management.
Mentor peers in documentation best practices and EMR workflows to streamline charting accuracy and billing compliance.
Engage in vendor evaluations by testing new dialyzers, tubing systems, and water treatment components and documenting performance and user feedback.
