✔✔Sleep walking, confusional arousals and sleep terrors most commonly accur when?
- ✔✔1-1.5hrs after sleep onset.
✔✔Which two sleep screening questionnaires have eight questions? - ✔✔Stop-bang
and epworth
✔✔An indication of narcolepsy is the observation of stage R in two or more naps with in
how many mins of falling asleep? - ✔✔15 mins
✔✔According to the national sleep foundation, the ideal bedroom temp for sleeping is
what? - ✔✔60-67 degrees
✔✔The sleep neurotransmitter that is responsible for the homeostatic sleep drive with
levels that's progressively increase during sustained wakefulness and decrease during
sustained sleeps is what? - ✔✔Adenosine
✔✔NREM sleep - ✔✔Heart rate-regular
Respiratory rate-regular
Blood pressure-regular
Muscle tone-preserved
Brain O2 consumption-reduced
Response to CO2-same as wake
Response to O2-same as wake
Temp-homeothermic
✔✔REM sleep - ✔✔HR-irregular
RR-irregular
BP-variable
Muscle tone-absent
Brain O2-increased
Response to CO2-decreased
Response to O2-same as wake
Temp-poikilothermic
✔✔How many processes are in sleep regulation? - ✔✔2 processes. Process S and
process C.
✔✔Process S (sleep) - ✔✔*sleep homeostasis-longer time awake, drive for sleep builds
up exponentially, then dissipates over the course of sleep.
*SWS/N3 decreases over successive, NREM sleep cycles reflects Process S with
higher N3 after sleep deprivation.
, ✔✔Price C (circadian) - ✔✔*endogenous circadian pacemaker is the suprachiasmatic
nucleus (SCN) of the hypothalamus.
*the brain's "master clock", which directs the 24hr cycle or endogenous biological
rhythm.
*body temp is a marker of the circadian rhythm, as are the hormones cortisol and
melatonin.
✔✔Who is at high risk for OSA? - ✔✔Older, overweight women with high blood
pressure, insomnia, disturbed sleep, or fatigue.
✔✔How much sleep do newborns need? - ✔✔16-18hrs, sleep is polyphasic.
✔✔polyphasic sleep - ✔✔a pattern of sleep that includes more than one period of sleep
during 24 hours.
✔✔16 weeks old - ✔✔14-15hrs
✔✔Age 2-5 years old - ✔✔Sleep 10-12 hrs
✔✔10 years old - ✔✔10 hrs, sleep becomes monophasic.
✔✔Moniphasic - ✔✔Sleep is condensed to only at night.
✔✔Adolescent age - ✔✔8-9, sleep duration declines and circadian phase delay starts.
✔✔circadian delay phase - ✔✔Later bedtime
✔✔What 3 things is affected with aging? - ✔✔Reduction in circadian, endocrine, and
metabolic.
✔✔What stage sleep decreases with age? - ✔✔N3, which is replaced by N1 and N2
sleep. REM has no significant decrease or increased sleep fragmentation.
✔✔Mid-life - ✔✔Decrease in growth hormone parallels decrease in SWS(N3).
✔✔adulthood - ✔✔7-8hrs
✔✔elderly - ✔✔Sleep time decreases and a biphasic pattern my desire-emerge,
circadian phase advance.
✔✔Circadian advance phase - ✔✔Earlier bedtimes
