AASM Sleep Staging Rules For
Children questions correctly answered
What is the age range for pediatric sleep staging rules? - correct answer ✔✔these rules can be
used to score sleep and wakefulness in children 2 months post-term or older
What adult electrode derivations are acceptable for pediatric sleep studies? - correct answer
✔✔the acceptable derivations are EEG, EOG and chin EMG
How far apart are the chin EMG electrodes in pediatric sleep study: - correct answer ✔✔these
are 1 cm apart in children as opposed to 2 cm apart in adults
how far apart are the EOG electrodes in pediatric sleep studies? - correct answer ✔✔these are
0.5 cm centimeters in children with small head size as opposed to 1 cm in adults
Why is there the presence of an ambiguous stage N in pediatric sleep studies? - correct answer
✔✔this stage exists for pediatric sleep studies as not all sleep waveforms are well developed by
2 months post-term
If all epochs of NREM sleep contain no recognizable sleep spindles, K complexes or high-
amplitude 0.5-2 Hz slow wave activity, what should the epoch be scored as? - correct answer
✔✔in this case, score as stage N
if some epochs of NREM sleep contain sleep spindles or K complexes, score those as stage N2. If
in the remaining NREM epochs, there is no slow wave activity comprising more than 20% of the
duration of epochs, how should it be scored? - correct answer ✔✔in this case, score as stage N
, if some epochs of NREM sleep contain greater than 20% slow wave activity, score these as stage
N3. If in the remaining NREM epochs, there are no K complexes or spindles, what should it be
scored as? - correct answer ✔✔in this case score as stage N
In an infant if NREM is sufficiently developed that some epochs contain sleep spindles or k
complexes and other epochs contain sufficient amounts of slow wave activity, how should
NREM sleep be scored? - correct answer ✔✔if this is the case, the NREM sleep in this infant
should be scored as stage N1, N2, or N3 as in an older child or adult
When are sleep spindles seen in infants? - correct answer ✔✔these are typically seen in infant
by age 6 weeks-3 months post-term and are present in all normal infants by age 2-3 months
post term
sleep spindles are present in all normal infants by age 2-3 months post term. how do they occur
in the brain? - correct answer ✔✔at this age, the spindles are asynchronous between the
hemispheres but become more synchronous over the first year of life
at what age are K complexes usually present? - correct answer ✔✔these are usually present by
age 3-6 months post term
EEG activity of 0.5-2 Hz with a typical amplitude of 100-400 microvolts in the frontal regions
may first appear by what age? - correct answer ✔✔this may appear by 2 months of age and is
usually present by age 4-5 months post-term
what is the criteria for slow wave activity in infants? - correct answer ✔✔the criteria for this in
infants is the same as in adults (amplitude greater than 75 microvolts of 0.5-2 Hz)
by what age in infants can NREM sleep be scored as stage N1, N2, N3? - correct answer ✔✔this
can be scored in most infants by age 5-6 months post-term and occasionally in infants as young
as 4 months post-term
