CHBT study guide

CHBT · Work through your exam, one topic at a time.

The Certified Hemodialysis Biofeedback Therapist (CHBT) credential is aimed at clinicians who combine two skill sets: a working command of the hemodialysis treatment environment and the ability to deliver biofeedback and relaxation training to patients during or around dialysis sessions. Candidates are typically nurses, dialysis technicians, and allied practitioners who want to help patients manage treatment-related distress, discomfort, and physiological arousal using structured psychophysiological techniques. The CHBT study guide has 6 sections and about 1,585 words.

01

Hemodialysis Fundamentals and Renal Physiology

Understand the twin jobs of dialysis - solute clearance by diffusion and fluid removal by ultrafiltration - and the physiology that makes them safe. Know the components of the extracorporeal circuit (access, blood pump, dialyzer, dialysate delivery, air detector, venous alarm), the difference between diffusion (concentration gradient), convection (solvent drag with transmembrane pressure), and osmosis.

02

Biofeedback Principles and Psychophysiology

Biofeedback is a learning process: a physiological signal is transduced, amplified, displayed, and fed back so the patient can gain voluntary control. Know the operant conditioning basis, the role of immediate and accurate feedback, and the concept of self-regulation.

272 words, about 1 min
03

Biofeedback Modalities and Instrumentation

Know the major modalities: electromyography, electrodermal (skin conductance), thermal, respiratory, heart rate variability, and electroencephalographic neurofeedback. For each, know the physiological source, typical sensor placement, and what the reading represents.

04

Application of Biofeedback During Hemodialysis Sessions

Delivering biofeedback during hemodialysis requires planning around a four-hour treatment, an immobile patient, and a busy unit. Know how to select candidates, set realistic goals, and sequence sessions: baseline assessment, short practice blocks, and review.

255 words, about 1 min
05

Patient Assessment, Symptom Management, and Relaxation Training

Know how to assess baseline arousal, symptom burden, anxiety, sleep, pain, and adherence. Use validated self-report measures and physiological baselines together.

06

Professional Practice, Safety, and Ethical Considerations

Know your scope of practice, the limits of your role within the dialysis team, and when to refer. Understand informed consent, privacy protections, and documentation standards.
