This RPSGT study guide follows the exam form in effect since September 1, 2023: four domains, each split into three tasks with a range of scored items. For each domain you get what is asked, the rules underneath, and the mistakes that cost technologists points. Two domains tie for the most weight, and PAP therapy is the single largest task.
The item ranges in each section count only the 150 scored questions; the pretest items are extra and do not count.
Scoring questions follow the current AASM Manual for the Scoring of Sleep and Related Events, so study from the current edition of the manual rather than from older textbook summaries.
BRPT's own Study Guide was written for the earlier blueprint (see the table below), so its domain list and weights will not match these bars. Use it for content and this outline for proportions.
Weights of the four domains on the current form; each bar opens its section below.
1Clinical Overview, Education, Patient Support. Task A, patient information and clinical assessment (10–14 items): clinician's orders and testing indications, history and physical, sleep disorders, medications, patient orientation, clinical baseline, questionnaires (e.g., Epworth Sleepiness Scale, STOP-BANG). Task B, patient and caregiver education (7–11 items): sleep hygiene, therapy and compliance, sleep disorder testing. Task C, therapy support (7–11 items): PAP desensitization, PAP application and mechanics, assessment of the download report.

Clinical Overview, Education, Patient Support (20%)
The smallest domain, and the one closest to the patient. Task A (10–14 items) covers the order and the indication for testing, history and medications, the sleep disorders behind a referral, and screening questionnaires such as the Epworth scale and STOP-Bang. Task B (7–11 items) is education: sleep hygiene, what the study involves, and why adherence to therapy matters. Task C (7–11 items) is therapy support, from PAP desensitization for an anxious patient to reading a PAP download report.
The disorder questions are practical rather than diagnostic: which patient needs a changed setup or extra monitoring, or which drug on the medication list will shift sleep latency or REM on tonight's study.
Hours of use do not prove therapy works
A download report can show long nightly use alongside a large leak or residual events that still need action. Read the usage, leak and residual event lines together before you call a patient's therapy a success.
Sleep Study Preparation and Performance (27.3%)
Task A (12–16 items) is technical preparation: equipment, 10–20 measurement and electrode placement, site preparation, instrument specifications, montages and infection control. Task B (11–15 items) covers protocols for adult and pediatric PSG, MSLT, MWT and home sleep apnea testing. Task C (12–16 items) is what you see during the night and what you do about it: abnormal EEG, artifacts, equipment faults, cardiac, respiratory, movement and capnography events, plus filters, sensitivity, calibration and impedance.
Placement questions are arithmetic first. Take the measured distance, apply 10 or 20 percent at the right step, then place the electrode; drill full head measurements on paper until the percentages come without thinking. For MSLT and MWT, keep the protocols apart: one asks the patient to fall asleep and the other to stay awake, and nap timing, room conditions and the end of each trial follow from that.
Fix the electrode before touching the filter
A 60 Hz notch filter can make a noisy channel look clean while the electrode under it keeps failing. Check and correct impedance first, keep each channel at the filter settings the protocol names, and document any change. Sweat, ECG pickup and muscle each leave a typical pattern; practice naming them from a single epoch.
Scoring, Reporting, and Data Verification (25.3%)
Adult scoring is the biggest task here (18–22 items): staging, arousals, respiratory events, desaturations, limb movements and cardiac events under the AASM rules. Pediatric and infant scoring (6–10 items) runs through the same list with age-specific rules, and report generation (8–12 items) asks you to compute and check indices and to read hypnograms, histograms and titration tables.
Report questions turn on definitions. The AHI divides events by hours of sleep; the RDI also counts respiratory effort–related arousals; the REI, used for home tests without EEG, divides by monitoring time because sleep itself is not measured. Write each formula out once with its denominator, and the report questions turn mechanical.
Children are not scored as small adults
Pediatric respiratory rules measure an event by missed breaths, two breath cycles, rather than the adult ten seconds, and infant staging uses stage names of its own. When a stem gives the patient's age, read it before choosing a rule.
Treatment and Intervention (27.3%)
This domain is mostly PAP: Task A, administering it, outweighs every other task on the exam (24–28 items). It spans CPAP, bilevel, auto-adjusting PAP, adaptive servo-ventilation and noninvasive ventilation: adult and pediatric titration guidelines, choice of mode, acclimation and mask fit, and troubleshooting leak, pressure relief and humidification. Task B (8–12 items) covers oral appliances, positional therapy and surgery; Task C (3–7 items) covers oxygen titration and when oxygen is or is not indicated.
Learn the titration algorithm as a list of thresholds: which events, how many and over how long before pressure goes up, when to move to bilevel, and when a central pattern calls for a different device rather than more pressure. The adult and pediatric versions differ, and the age given in the question decides which set applies.
Oxygen comes after pressure
During a titration, supplemental oxygen is added only once PAP has controlled the obstructive events and saturation still stays low. Adding it sooner hides events that pressure should have treated.

Clinical overview · 20%Q1 of 12
Which feature distinguishes nightmares from sleep terrors?
Mark a letter. The key, plus a line on every option, opens at once.
Onset in the first third of the night
The first third is when N3 is densest, which is when sleep terrors cluster; nightmares lean toward the REM-rich last third.
Arousal out of stage N3
Arousal from N3 is the sleep-terror pattern; a nightmare ends a REM period instead.
Little or no recall afterward
Little or no recall afterward belongs to sleep terrors and other NREM arousal disorders, not to dreams that wake the person.
Full alertness with vivid recall
Nightmares come out of REM, so the sleeper wakes with full alertness and vivid recall of the dream.
Clinical overview · 20%Q2 of 12
A patient asks why an in-lab PSG was ordered instead of HSAT. Which history item justifies the PSG?
Chronic opioid use
Chronic opioid use raises the risk of central apnea and hypoventilation, which home testing cannot evaluate, so the AASM steers these patients to attended PSG.
Loud nightly snoring
Loud nightly snoring points toward OSA itself and gives no sign of the breathing problems an attended study is needed for.
BMI of 34 kg/m²
A BMI of 34 is a risk factor for OSA; it explains why testing was ordered, not why the lab was chosen.
Age of 58 years
An age of 58 is another OSA risk factor and says nothing about central apnea or hypoventilation.
Clinical overview · 20%Q3 of 12
A diary and the prior PSG show adequate sleep. The MSLT gives a mean sleep latency of 5 min with 3 SOREMPs, and there is no cataplexy. Which diagnosis is MOST consistent?
Narcolepsy type 1
Narcolepsy type 1 needs cataplexy or a low CSF hypocretin level; cataplexy is absent and no hypocretin result is given.
Narcolepsy type 2
Mean latency of 8 min or less with at least 2 SOREMPs, no cataplexy and adequate prior sleep fits type 2.
Idiopathic hypersomnia
Idiopathic hypersomnia requires fewer than 2 SOREMPs; three SOREMPs move the diagnosis to narcolepsy.
Insufficient sleep syndrome
The sleep diary and the prior PSG document enough sleep, so chronic sleep restriction has been excluded.
Study prep and performance · 27.3%Q4 of 12
Where is Cz located in the 10-20 system?
30% up from the nasion
Thirty percent from the nasion marks Fz, a frontal midline site in front of Cz.
At both 50% midpoints
Cz sits at both 50% midpoints: halfway along the nasion-inion line and halfway along the preauricular line.
20% up from the inion
20% up from the inion falls between Oz (10%) and Pz (30%), well behind the vertex.
Midway from C3 to T3
Halfway between C3 and T3 is not a 10-20 position; Cz is on the midline, not lateral.
Study prep and performance · 27.3%Q5 of 12
Which chin EMG derivation is standard per AASM?
Chin1-Chin2
Chin1-Chin2 links the two submental electrodes, a lab habit, but the manual's derivation uses ChinZ as the reference.
ChinZ-M1
ChinZ is the reference for the submental electrodes, not an active lead paired with a mastoid.
Chin2-M2
Chin2-M2 references a chin electrode to a mastoid, which picks up EEG and ECG and is not an AASM chin derivation.
Chin1-ChinZ
Chin1-ChinZ pairs an electrode below the mandible with the midline ChinZ above it, the AASM pattern; the spare submental electrode is a backup.
Study prep and performance · 27.3%Q6 of 12
An unattended home study that records EEG, EOG, chin EMG, ECG, airflow, effort and SpO₂ is classified as:
Type II
A Type II device records a full sleep montage, including EEG, outside the lab without a technologist present.
Type I
Type I is the attended in-lab PSG; the unattended home setting excludes it.
Type III
Type III devices record cardiorespiratory channels only, so the EEG, EOG and chin EMG listed here exceed them.
Type IV
Type IV covers one or two channels, typically oximetry with or without airflow.
Scoring and reporting · 25.3%Q7 of 12
In infants 0–2 months post-term, sleep onset typically occurs into stage:
N
N (infant NREM, quiet sleep) as the entry stage is the adult expectation applied to a newborn.
T
Stage T labels epochs with mixed NREM and R features; it is not where sleep usually begins.
R
Young infants usually fall asleep straight into R (active sleep), the reverse of the adult sequence.
N1
Infant scoring does not subdivide NREM, so N1 is not a stage used at this age.
Scoring and reporting · 25.3%Q8 of 12
After an N1 epoch, the next epoch shows low-amplitude mixed-frequency EEG, unchanged chin tone and a 0.3-s sharp wave maximal over the central region, with no spindles. How is this epoch scored?
R
R needs low chin tone together with rapid eye movements or a preceding R epoch; here chin tone is unchanged after N1 and R features are not described.
W
Vertex sharp waves are a sign of drowsy sleep, and no alpha or wake EEG is described.
N1
A central sharp wave shorter than 0.5 s is a vertex sharp wave, a feature of N1, so the epoch stays N1.
N2
Calling the 0.3-s wave a K complex is the trap; a K complex lasts 0.5 s or more and is maximal frontally.
Scoring and reporting · 25.3%Q9 of 12
Per AASM, consecutive leg movements in a PLM series must have an onset-to-onset interval of:
5–90 s
AASM counts leg movements as one PLM series when consecutive onsets are 5 to 90 s apart, with at least 4 movements.
0.5–10 s
Half a second to 10 s is the allowed duration of a single leg movement, not the gap between movements.
5–30 s
A 30-s ceiling would exclude movements with the long intervals the rule explicitly includes, up to 90 s.
15–120 s
A 15–120 s window is not an AASM value and would drop many short-interval movements from the series.
Treatment · 27.3%Q10 of 12
According to AASM PAP titration grading, a repeat titration should be considered when the initial titration fails to achieve which minimum grade?
Adequate or better
Adequate titrations still leave enough residual events that a repeat night is to be considered.
Optimal only
Requiring optimal would send good titrations, which control events with supine REM recorded, back for another night.
A 75% RDI reduction
A 75% fall in RDI is one of the criteria for an adequate titration, which is below the level that avoids a repeat.
Good or optimal
The 2008 titration guideline suggests a repeat study when the first night reaches neither good nor optimal.
Treatment · 27.3%Q11 of 12
During CPAP titration in an 8-year-old, how many obstructive hypopneas must be observed before the pressure is increased?
2
Two obstructive apneas is the adult apnea trigger; children need only one event of this kind.
3
Three hypopneas is the threshold for patients 12 and older, not for an 8-year-old.
1
Under age 12, a single obstructive hypopnea is enough to raise CPAP during titration.
5
Five is the older-patient RERA threshold and has nothing to do with pediatric hypopneas.
Treatment · 27.3%Q12 of 12
Uvulopalatopharyngoplasty (UPPP) mainly alters which structure?
Base of the tongue
Tongue-base procedures target the hypopharynx, below the level UPPP works on.
Soft palate and uvula
UPPP trims and reshapes the uvula, soft palate and tonsillar tissue at the velopharynx.
Nasal septum and turbinates
The septum and turbinates are treated by septoplasty and turbinate reduction for nasal obstruction.
Mandible
Moving the mandible forward is maxillomandibular advancement, a different surgery.
By weight first, then by weakness: the bars at the top of this page show where the scored items sit. After a first pass, the practice test shows which domain is pulling your score down.
Is BRPT's Study Guide enough for the current form?
It works as a content review, but it was built on the earlier blueprint, so its weights and domain list no longer match the exam you will sit. Pair it with the current outline on this page.
Which scoring rules does the registry exam use?
The current edition of the AASM Manual for the Scoring of Sleep and Related Events. Check which edition your textbook follows before trusting its scoring examples.
