The 24-hour circadian rhythm affects which pysiological assement data?
When does a persons body temperature usually peak during the day? when does it sharply fall?
Falls= after the person falls asleep
what part of your body is your major sleep center?
What do the "special" cells located in the RAS do for us?
maintenance of consciousness
what happens as stimuli to the RAS declines?
what are the 2 stages of normal sleep?
non-rapid eye movement (NREM)
Rapid eye Movement (REM)
what are the four stages of NREM? how long does it take to progess through 1 cycle of NREM?
how long does each stage last? what happens to VS in each stage?
90 minutes= 1 cycle
1.) lightest level. last only a few minutes. decreased physiological activity begin w/ gradual fall in VS and metabolism. Sensory stimuli such as noise easily arouses person. when they awake they feel like they were day dreaming.
2.) sound sleep. Relaxation progresses. Arousal remains relatively easy. Stage last 10-20 minutes. Body functions contiune to slow.
3.) initial stages of deep sleep. Sleeper is difficult to arouse and rarely moves. muscles are completely relaxed. VS declines but remain regular. Stage last 15-30 minutes.
4.) Deepest stage of sleep. Very difficult to arouse sleeper. If sleep loss has occured sleeper will spend majority of sleep in this stage. VS are significantly lower than waking hours. stage approxiamely 15-30 mins. sleepwalking & enuresis may occur
out of the 2 normal stages of sleep, which one do you have vivid dreams?
What is typified in REM?
Rapidly moving eyes
Fluctuating HR & RR
Increased of fluctuating BP
How many passes through the sleep cycle do you complete per ngiht? How long do each complete cycle last?
In what order do we go through the sleep cycle?
1-4 and then reversal 4,3,2 then REM
What % of sleep do we spend in NREM a night?
What is our HR (on average) when we are a sleep?
what are the biological functions that decrease during sleep
what types of diseases alter rythym of breathing during sleep?
which sex has sleep problems more often? And what disease is it associated with?
Coronary artery disease
Sleep related breathing disorders are linked to increased....? What diseases and assessment findings?
risk for heart disease

Nocturia disrupts sleep and the sleep cycle. which diseases are associated w/ nocturia?
older adults w/ reduced bladder tone
What is restless leg syndroms (RLS)?
people experience recurrent rythmical movments of legs; occurs just before sleep. Client feels itching sensation deep in the muscle. relief is only achieved by moving the legs.
There are two types RLS what are they and what do they indicate?
primary RLS= nervous system disorder
secondary RLS= low levels of iron, pregnancy, and uremia
symptom clients experience when they ahve chronic difficulty falling asleep, frequent awakening from sleep/or a short non-restorative sleep
what are the 3 different types of insomnia?
define transient insomnia.
experienced as a result of situational stress such as family, work, school, jet lag, illness, loss of loved one
misalignment of timing of sleep and what the individual desires or the societal norm
undersirable behaviors that occur usually during sleep
Someone who has chronic insomnia will have these symptoms
define sleep apnea.
disorder characterized by the lack of airflow through the nose and mouth for a period of 10 seconds or longer during sleep
what are some S/S?
excessive daytime sleepiness
decreased sex drive
what are the 3 types of apnea?
Tell me everything you know about CSA :)
less than 10% apnea is this kind
involves dysfunction of brain's respiratory control center
impulse to breathe fails, nasal airflow and chest wall movement cease. oxygen saturation falls.
common in clients w/ brain stem injury, muscular dystrophy and encephalitis and people who breathe normally during the day
Complain of insomnia
what type of apnea does 12-18 million people in the use have?
Who are common people to have Obstructive Apnea?
what cause the obstruction in obstructive apnea?
muscles or structures of oral cavity or throat relax
upper airway become partially/completely blocked
diminishing airflow (hypopnea) or stopping (apnea) for 30 secs
OSA puts individual at risk for what type of physiological issues
right heart failure
dysfunction of mechanisms that regulate the sleep and wake states
what is cataplexy?
sudden muscle weakness during intense emotions such as anger, sadness, or laughter
what is a symptom of narcolepsy?
sleep paralysis (feeling of being unable to move or talk jsut before waking or falling asleep)
what are tx for narcolepsy:
wakefulness promoting agents (modanfinil)
short (20 min) naps
avoiding shifts in sleep
eating light meals high in protein
practicing deep breathing
what do narcoleptic need to avoid?
long periods of sitting in hot, stuffy rooms
what type of things cause sleep deprivation cause?
variability of timing of sleep (shift work)
what are physiological symptoms of sleep deprivation?
fine motor clumsiness
slowed response to time
decreased reasoning & judgement
decreased auditory & visual alertness
what are the psychological symptoms of sleep deprivation?
increased sensitivity to pain
