- Electromyogram (EMG)
-Respiratory Measurements
- Electrocardiogram (ECG)
What do respiratory tools used to measure sleep record? correct answersEffort - string gate belt
wrapped around your chest as you breathe
Flow -
Oxygen levels - pulse oximeter
Polysomnography correct answersrecording multiple aspects of sleep use an EEG to record brain waves,
the oxygen level in your blood, heart rate and breathing as well as eye and leg movements during the
study
Differentiate between the stages of sleep based on EEG parameters correct answers
, EEG stages of sleep - awake correct answerslow amplitude, fast activity, beta frequency range 15-25 or
30 hertz/cycles per second
EEG stages of sleep - drowsy correct answers
EEG stages of sleep - Stage 1 (aka N1) correct answerslightest stage of sleep, lasts a few minutes of the
night, associated with transitions, theta activity, 4-7 cycles per second/hertz, we see vertex sharp waves
especially in the center of the brain
Which of the following is a characteristic of stage 1 sleep?
slow rolling eye movements
rapid eye movements
beta waves
delta waves correct answersslow rolling eye movements
EEG stages of sleep - Stage 2 (aka N2) correct answersa part of non-REM sleep, as adults we spend 50%
of the night in this stage of sleep, background is theta, sleep spindles, K complexes, eyes are barely
moving
sleep spindle correct answersa burst of activity, 12-14 cycles per second. initiated in the thalamus ( a
sensory relay center) primarily but also other deep centers of the brain. thalamocortico isolation
In what stage of sleep during what phenomena do thalamocortico isolations occur? correct
answersduring the sleep spindles of stage 2. inhibitory waveform as information is not sent to the cortex
during these sleep spindles.
K complexes correct answersrespond to external and internal stimulus. they have something to do with
the wakeful process. don't always wake up when you have one but these are present every-time you
