What are the rules for scoring epochs with major body movement?
a) if alpha rhythm is present for part of the epoch, score as W; b) if no alpha is
discernible, but an epoch scorable as stage W either precedes or follows the epoch with
a major body movement, score as W; c) otherwise, score the epoch as the same stage
that follows it.
What is the rule for scoring arousals?
Score arousal during sleep stages N1, N2, N3 or R if there is an abrupt shift of EEG
frequency including alpha, theta and/or frequencies > 16 Hz (but not spindles) that lasts
at least 3 seconds, with at least 10 seconds of stable sleep preceding the change.
What is the typical filter settings for EEG channels?
LFF 0.3 Hz, HFF 35 Hz
What is the typical filter settings for EOG channels?
LFF 0.3 Hz, HFF 35 Hz
What is the typical filter settings for EMG channels?
LFF 10 Hz, HFF 100 Hz
What is the typical filter settings for EKG channels?
LFF 0.3 Hz, HFF 70 Hz
What is the criteria for scoring stage N1?
attenuated alpha rhythm replaced by low amplitude mixed frequency activity for more
that 50% of epoch
How is sleep latency different in those that do not generate alpha rhythm?
it is shorter than normal
What are the scoring criteria for stage R sleep?
,a) low amplitude, mixed frequency EEG; b) low chin EMG tone; c) rapid eye movements
What are the rules for stage N1 in patients that do not generate alpha?
4-7 Hz activity with slowing background frequencies by at least 1 Hz from Wake, vertex
sharp waves and slow eye movements
What kind of eye movements are typical in N3 sleep?
eye movements are not typically seen during stage N3 sleep
What are some characteristics of stage R sleep?
rapid eye movements, low chin EMG tone; sawtooth waves in 2-6 Hz over central head
regions, often preceding a burst of rapid eye movements; transient muscle activity
What is the rule that defines the continuation of stage N2 sleep?
Continue to score epochs with low amplitude, mixed frequency EEG activity without K
complexes or sleep spindles as stage N2 if they are preceded by a) K complexes
unassociated with arousals or b) sleep spindles
What criteria define the end of a period of stage N2 sleep?
End stage N2 sleep when 1 of the following occur: a) transition to stage W; b) an
arousal changes it to stage N1 until a K complex unassociated with an arousal or a
sleep spindle occurs; c) a major body movement followed by slow eye movements and
low amplitude mixed frequency EEG without nonarousal associated K complexes or
sleep spindles; d) transition to stage N3; e) transition to stage R.
What is the rule that defines the continuation of a period of stage R sleep?
, Continue to score stage R sleep, even in the absence of rapid eye movements, for
epochs following 1 or more epochs of stage R if the EEG continues to show low
amplitude mixed frequency activity without K complexes or sleep spindles and the chin
EMG tone remains low.
What are the rules defining the end of stage R sleep?
a) there is a transition to stage W or N3; b) an increase in chin EMG tone above the
level of stage R is seen and criteria for N1 are met; c) an arousal occurs followed by low
amplitude, mixed frequency EEG and slow eye movements, which would be scored as
N1; d) a major body movement followed by slow eye movements and low amplitude
mixed frequency EEG without non-arousal associated K complexes or sleep spindles;
e) one or more non-arousal associated K complexes or sleep spindles are present in
the first half of the epoch in the absence of rapid eye movements, even if chin stays low.
What is the typical filter settings for respiratory channels?
LFF 0.1 Hz, HFF 15 Hz
