What are typical filter settings for EMG channels? -Answer: LFF 10 Hz, HFF 100 Hz
What are typical filter settings for EKG channels? -Answer: LFF 0.3 Hz, HFF 70 Hz
What is the typical filter settings for respiratory channels? - Answer LFF 0.1 Hz, HFF 15
Hz
What is the typical filter settings for snoring channels? - Answer LFF 10 Hz, HFF 100 Hz
What is the placement of E1? - Answer 1cm below the left outer canthus
What is the placement of E2? - Answer 1cm above the right outer canthus
Where are the chin electrodes placed? - Answer One in midline 1cm above inferior edge
of mandible; one 2cm below inferior edge of mandible and 2cm to the right of the
midline; one 2cm below inferior edge of mandible and 2cm to the left of the midline.
What are the criteria of stage W? -Answer Alpha rhythm in the occipital regions;
conjugate vertical eye movements of 0.5 - 2Hz; trains of conjugate eye movements
consisting of a slow phase followed by a rapid phase in the opposite direction; rapid eye
movements; and normal or high chin EMG
, What are the criteria to score stage W? - More than 50% of the epoch displays alpha
rhythm over the occipital region. In the absence of apparent alpha and one or all of the
following are present, a) eye blinks of 0.5-2 Hz; b) reading eye movements; c) irregular
conjugate rapid eye movements associated with normal or high chin muscle tone
What are the criteria for scoring a stage as N1? -Answer slow eye movements that are
reasonably regular and have an initial deflection usually lasting >500 msec; low
amplitude, mixed frequency activity; vertex sharp waves; and sleep onset
What are the criteria for scoring a stage as N2? - Answer If one or both occur during the
first half of the epoch or the last half of the previous epoch. a) one or more k complexes
unassociated with arousals b) one or more trains of sleep spindles
What are the criteria for scoring stage N3? -Answer 20% or more of epoch consists of
slow wave activity (0.5 - 2 Hz with peak to peak amplitude of >75 uV measured over the
frontal regions)
What is a vertex sharp wave? -Answer Sharply contoured waves with a duration of <0.5
seconds maximal over the central regions and distinguishable from the background
activity.
What is scoring stage N1 criteria: Answer Attenuated alpha rhythm replaced with
low-amplitude mixed-frequency activity more than 50% of an epoch
Sleep latency differences in those people who do not generate any alpha rhythm, how?
That is shorter compared to the normal type
What is used to score stage R sleep? Answer: a) low amplitude, mixed frequency EEG;
b) low chin EMG tone; c) rapid eye movements
What are the criteria for stage N1 in non-alpha-generating individuals? Answer: 4-7 Hz
activity with slowing background frequencies by at least 1 Hz from Wake, vertex sharp
waves and slow eye movements
