  1. Cheyne-Stokes breathing on PSG is characterized by which pattern?

    Answer: Crescendo-decrescendo breathing with central apneas

    Cheyne-Stokes breathing shows a crescendo-decrescendo tidal volume pattern alternating with central apneas, often seen in heart failure patients.

  2. What is the standard low-frequency filter (high-pass filter) setting for EEG channels in PSG?

    Answer: 0.3 Hz

    The standard low-frequency filter for EEG in PSG is 0.3 Hz, which preserves slow wave activity while reducing movement artifact.

  3. Which sleep stage is associated with the highest arousal threshold (hardest to wake from)?

    Answer: Stage N3

    Stage N3 (slow wave sleep) has the highest arousal threshold, making it the most difficult stage from which to arouse a patient.

  4. Which chin EMG finding is required to score an epoch as REM sleep?

    Answer: Relatively low chin EMG tone

    REM sleep requires relatively low (atonic) chin EMG tone, reflecting muscle atonia that is a hallmark of REM sleep.

  5. A sleep onset REM period (SOREMP) occurring within how many minutes of sleep onset is considered clinically significant for narcolepsy?

    Answer: 15 minutes

    A SOREMP within 15 minutes of sleep onset on PSG or within 20 minutes on MSLT is a diagnostic criterion for narcolepsy type 1.

  6. What is the total recording time (TRT) measurement used to calculate sleep efficiency?

    Answer: Time from lights-off to lights-on

    Sleep efficiency is calculated as total sleep time divided by time in bed (lights-off to lights-on) × 100%.
