,BRPT RPSGT EXAM GUIDE HSAT & STUDY TYPES
How to Use This Guide
Read each stem, choose your answer, then check the rationale directly below it. The correct option is marked, and each
wrong option is explained so you understand why it's wrong — not just that it is.
HSAT & Sleep Study Types
1 What channels are included in PAT (Peripheral Arterial Tone) equipment?
A PAT signal, heart rate, oximetry, actigraphy, body positioning, snoring, and chest motion
B EEG, EOG, EMG, ECG, and oximetry
C EEG, oximetry, and respiratory effort
D Nasal pressure, thermistor, and pulse oximetry
Why A is correct: PAT equipment includes 7 channels: PAT signal, heart rate, oximetry, actigraphy, body positioning,
snoring, and chest motion.
B — PAT does not include EEG or EOG.
C — PAT includes more than just these channels.
D — These are HSAT channels but not PAT-specific.
2 What are the indications for HSAT (Home Sleep Apnea Testing)?
A Conditions that place the patient at increased risk of non-obstructive sleep-disordered breathing
B All patients with suspected sleep apnea
C Patients with severe insomnia
D Patients with REM behavior disorder
Why A is correct: HSAT is indicated for patients at increased risk of non-obstructive sleep-disordered breathing,
including central sleep apnea, hypoventilation, and sleep-related hypoxemia.
B — Not all patients are candidates for HSAT.
C — HSAT is not indicated for insomnia.
D — RBD requires in-lab PSG.
, 3 When scoring a home sleep study, monitoring time is defined as:
A Total recording time minus periods of artifact and the time the patient was awake
B Total recording time from lights out to lights on
C Total sleep time
D Time from patient hook-up to disconnection
Why A is correct: Monitoring time in HSAT is total recording time minus periods of artifact and time the patient was
awake.
B — This is TRT in in-lab PSG.
C — TST cannot be determined in HSAT.
D — This is not the definition.
4 According to recommended guidelines, unattended portable monitoring can be used as an alternative to in-
lab testing when:
A There is a high probability of moderate to severe OSA WITHOUT comorbid conditions
B There is a high probability of mild OSA
C The patient has severe COPD
D The patient has central sleep apnea
Why A is correct: Portable monitoring is recommended for patients with a high probability of moderate to severe OSA
and no comorbid conditions.
B — Mild OSA is not typically diagnosed with HSAT.
C — COPD is a comorbid condition.
D — Central sleep apnea requires in-lab testing.
