Multiple Sleep Latency Test (MSLT) correct answers What does the acronym "MSLT" refer to?
A series of five nap opportunities is standard. correct answers How many nap opportunities are
usually included in the clinical MSLT protocol?
The first nap should start 1.5 to 3 hours after completing the polysomnogram. correct answers
When is the appropriate time to start the first MSLT nap?
The test should continue for 15 minutes following the first epoch of any sleep stage. correct
answers After sleep onset (defined as the first epoch scored as any stage of sleep) when should
the nap opportunity be terminated in a MSLT?
The test should be terminated after 20 minutes of recording. correct answers If no sleep occurs
during a nap opportunity in a MSLT, when should the test be terminated?
The first 30- second epoch scored as any stage of sleep. correct answers What is the definition of
sleep latency?
The elapsed time in minutes from the first epoch of sleep to the first epoch of REM sleep. correct
answers What is the definition of REM sleep latency?
The MSLT is performed for objective evaluation of daytime sleepiness. correct answers What is
the indication for performing a MSLT?
Two hours after the start of the previous nap. correct answers What is the appropriate interval
between nap opportunities during the MSLT?
30 minutes. correct answers How long before a nap opportunity begins should the patient
discontinue smoking?
The test is recorded in 30-second epochs. correct answers What epoch length is used during a
MSLT recording?
The presence of pathological sleepiness. correct answers What does a meal sleep latency of <5
minutes during a MSLT generally indicate?
At least two naps. correct answers in order to confirm the diagnosis of narcolepsy using a MSLT,
how many nap opportunities must contain a sleep onset REM?
Excessive daytime sleepiness (EDS) or sleep attacks. correct answers What is usually the first
symptom of narcolepsy to emerge?
F4/M1 or F3/M2, C4/M1 or C3/M2, O2/M1 or O1/M2, E1, E2 Chin EMG, ECG. correct
answers What is the minimally required recording montage for the MSLT?
, Sum of the individual sleep latencies for each nap divided by the total number of naps. correct
answers How is mean sleep latency calculated in the MSLT recording?
Every 2 hours. correct answers How frequently are nap opportunities scheduled during the
MSLT?
The Multiple Sleep Latency Test (MSLT) and the Maintenance of Wakefulness Test (MWT)
correct answers What two tests are the only objective measures currently available to quantify
sleepiness in a patient?
20 Minutes. correct answers If sleep does not occur during a MSLT nap opportunity, how many
minutes are recorded after lights-out?
15 minutes correct answers In order to assess the occurrence of REM sleep during a MSLT, how
many minutes should the test continue after the first epoch of sleep?
Excessive daytime sleepiness, cataplexy, hypnagogic hallucinations and sleep paralysis. correct
answers What are the four major symptoms of narcolepsy?
Type II correct answers Type of portable monitor consisting of 8 channels, including: EEG,
EOG, chin EMG, ECG, airflow, respiratory effort, and oxygen saturation.
Minimum of 3 recorded channels. correct answers CMS definition of Type IV home sleep test.
An in-lab sleep study. correct answers If a home sleep test is negative in a patient with a high
pretest liklihood of having OSA, what is then indicated?
Severe pulmonary disease, neuromuscular disease, CHF, CSA, narcolepsy, PLMD, parasomnias,
circadian rhythm disorders. correct answers Contraindications for portable monitoring.
40 Minutes correct answers How long should an MWT nap last?
Maintenance of Wakefulness Test (MWT) correct answers Which sleep study measures the
ability to resist the urge to fall asleep?
Frontal, Central, & Occipital EEG; Left and right EOG; chin EMG; and ECG correct answers
Which channels are required in an MWT montage?
Pooling of water in the tubing (rain-out) correct answers What will result from excessive
warming in the inside of PAP tubing and/or excessive cooling of air outside of the tubing?
Adaptive sero-ventilation (ASV) correct answers Patients with Cheyne-Strokes breathing die to
CHF would most likely benefit from which PAP mode?
