RPSGT study guide
RPSGT · Work through your exam, one topic at a time.
The Registered Polysomnographic Technologist (RPSGT) credential is awarded by the Board of Registered Polysomnographic Technologists (BRPT), an independent nonprofit certification board that describes itself as setting the professional standard for sleep health professionals. First administered in 1979, the RPSGT is described by BRPT as the internationally recognized gold standard certification for sleep professionals; 16,728 certifications were current as of March 25, 2026, and BRPT reports credential holders in 34 countries. The credential is intended for people already working in sleep technology who are ready to demonstrate full clinical competency: performing and scoring sleep studies, applying clinical knowledge in real-world settings, and meeting professional standards for patient care. Candidates need clinical experience in polysomnography, relevant education or training, and a current BLS certification or equivalent; BRPT offers multiple eligibility pathways based on training and experience. The RPSGT study guide has 4 sections and about 1,316 words.
01Patient and Equipment Preparation for Polysomnographic Testing
Preparation starts at scheduling. Confirm the indication, obtain informed consent, and collect a sleep diary (usually 1–2 weeks) plus a full medication list - sedatives, stimulants, opioids, and antidepressants all reshape the tracing (many antidepressants suppress REM and increase chin EMG tone).

The amplifier must be set so the signals of interest are faithfully captured. EEG is sampled at a minimum of 200 Hz and commonly 500 Hz; the Nyquist principle requires sampling at least twice the highest frequency you intend to record, which is why anti-aliasing filters exist.

Scoring uses 30-second epochs, assigned by the majority of the epoch. Wake: alpha rhythm over the occipital region for more than half the epoch (with eyes closed).

During a PAP titration the technologist raises pressure until apneas, hypopneas, hypoxemia, and arousals are eliminated, with the goal of covering supine REM sleep. A split-night study is generally appropriate when the diagnostic portion shows an AHI ≥40 in the first 2 hours, or 20–40 with clinical judgment, and at least 3 hours remain for titration.
