Q

Sleep involves a sequence of physiological states maintained by highly integrated CNS activity. It is associated with changes in the peripheral nervous, endocrine, cardiovascular, respiratory and muscular systems.

Q

major sleep center in the body

It secretes hypocretins (orexins) that promote wakefulness and rapid eye movement (REM)

Prostaglandin D2 L-tryptophan, and growth factors control sleep

Q

maintains a state of wakefulness and mediates some stages of sleep. Sleep is an active process involving the RAS
- And a dynamic interaction of neurotransmitters.

Q

is a major neurotransmitter associated with sleep. It is derived from its precursor tryptophan. Other neurotransmitters- acetylcholine and norepinephrine appear to be required for the REM sleep cycle.

Q

A phase of normal sleep

A sleeper progresses through four stages during a typical 90-minute sleep cycle

The quality of sleep from stage 1 through stage 4 becomes increasingly deep

Stages 1 and 2 is characterized by lighter sleep, person is more easily aroused

Stage 3 and 4 involve a deeper sleep (slow-wave sleep)

A

Q

Stage lasts a few minutes
Lightest level of sleep
Decreased physiological activity begins with gradual fall in vital signs and metabolism
Sensory stimuli such as noise easily arouse a person
When awakened, person feels as though daydreaming has occurred

Q

Stage usually begins about 90 minutes after sleep has begun
Duration increases with each sleep cycle and averages 20 minutes
Vivid, full color dreaming occurs in other stages
Stage is typified or fluctuating BP, loss of skeletal muscle tone and increase in gastric secretion
It is very difficult to arouse a sleeper

A

Rapid Eye Movement (REM) sleep

18
Q

contributes to body tissue restoration

A

NREM Sleep

19
Q

increases in synthetic processes in the brain

20
Q

A symptom that patients experience when they have chronic difficult falling asleep, frequent awakenings from sleep and/or short sleep or nonrestorative sleep

Associated with poor hygiene or practices that a patient associates with sleep

Tx: sleep-hygiene measures, biofeedback, cognitive techniques, relaxation techniques

21
Q

Dysfunction of mechanisms that regulate sleep and wake states
Overwhelming sleepiness
Uncontrolled REM

A

Narcolepsy “Sleep Attack”

22
Q

Is a disorder characterized by the lack of airflow through the nose and mouth for periods of 10 seconds or longer during sleep
Periodic cessation of breathing during asleep. It characterized by snoring

A

Sleep apnea

23
Q

Excessive sleep (daytime or nighttime)
Related to psychologic problem, CNS damage, metabolic disorders

A

Hypersomnia

24
Q

Problem many patients experience as a result of dysomnia. Causes includes symptoms caused by illnesses, emotional stress, medications, environmental disturbances and variability in the timing of sleep because of shift work

A

Sleep deprivation

Factors influencing sleep
Drugs and substances Lifestyle Usual sleep patterns Emotional stress Environment Exercise and fatigue Food and caloric intake
41
Nursing interventions to promote sleep
Helping nurse-patient relationship Promote comfort and relaxation Create restful environment Attend to bedtime rituals Adequate exercise (at least 2 hours before sleep to enhance NREM; not immediately before sleep) High protein food Observe habits of sleep periodicity and wake-up time Avoid caffeine and alcohol in the evening If sleepy, go to bed Bed is used mainly for sleep
