CPSGT study guide
CPSGT · Work through your exam, one topic at a time.
The Certified Polysomnographic Technician (CPSGT) is the entry-level credential offered by the Board of Registered Polysomnographic Technologists (BRPT) for individuals new to sleep technology. Its stated purpose is to validate foundational knowledge and give new technologists a defined starting point in the field, rather than to certify advanced practice. Candidates typically come from one of several eligibility pathways based on training or coursework - including enrollment in or completion of a sleep technology CAAHEP/CoA or STAR sleep education program - combined with early clinical experience in polysomnography and at least a GED or higher degree. The credential is positioned as a bridge: it is meant to support safe, supervised clinical experience and to prepare candidates to pursue the RPSGT. The CPSGT study guide has 4 sections and about 1,180 words.
01Foundational Sleep Technology Knowledge
CPSGT foundational knowledge centers on normal sleep and the signals used to describe it. Know the 30-second epoch and the standard stages: W, N1, N2, N3, and R.
338 words, about 2 min02Patient Preparation and Testing Setup
Patient preparation begins before electrodes are applied: verify identity, explain the procedure, obtain consent per policy, and review history, medications, allergies, and recent sleep. Measure the head using landmarks such as nasion, inion, and preauricular points to place electrodes by the 10–20 system.
291 words, about 1 min03Data Acquisition, Recording, and Documentation
Data acquisition covers the polysomnographic montage, filters, sensitivity, sampling rate, and documentation. Know the purpose of each channel: EEG for staging, EOG for eye movements, chin EMG for muscle tone, ECG for rhythm, airflow and effort for respiratory events, oximetry for oxygen saturation, and sensors for snore, position, and limb movements.
292 words, about 1 min04Entry-Level Clinical Tasks and Supervised Care
Entry-level clinical tasks are performed under supervision and within scope. Know PAP basics: CPAP provides fixed positive pressure, while BiPAP provides inspiratory and expiratory pressures; titration follows orders and protocol.
