hypothalamus
The ______ ________ _______ ___located in the brainstem releases catecholamines (norepinephrine) that help us stay awake and alert.
reticular activating system (RAS)
The ________ ______ __ _______ _____(process S) regulates length and depth of sleep. (Gets stronger the longer we are awake and declines during sleep).
homeostatic process or sleep drive
what is the major sleep center

hat does the hypothalamus control?
wakefulness and rapid eye mvm (REM) sleep
what can be affected by sleep/wake cycle
light, temperature, social activities, and work routines. Different people function better at different times of the day.
what is sleep regulated by…
physiological changes in the peripheral nervous, endocrine, cardiovascular, respiratory, and muscular systems which are maintained by the central nervous system.
_____ ______ are physical, mental, and behavioral changes that follow a 24-hour cycle. Sleep and waking periods are the most common example of this.
It influences the patterns of body temperature, heart rate, blood pressure, hormone secretion, sensory acuity and mood, so maintaining _________ _________ is important to proper functioning biologically and behaviorally.
circadian rhythms
how long do sleep cycles last
around 90 to 110
how may stages of the sleep cycle are there?
2 primary stages of a sleep cycle: non-rapid eye movement (NREM) and rapid eye movement (REM).
what is the sleep cycle determined by?
depends of the total length of time that they sleep; the amount of time spent in each stage the sleep cycle varies
what is there before sleep?
pre-sleep period
what is the pre-sleep period
where the person gradually becomes sleepy. This usually lasts 10 to 30 minutes, but longer if the person is having trouble falling asleep.
How many stages are the in NREM
3 stage; occurs once the person is asleep and lasts around 90 minutes
what is N1
lightest sleep and lasts only a few minutes. Gradual decrease of vital signs/metabolism. Can easily be awoken by noise.
what is N2
sound sleep. relaxation is progressing. Brain and muscle activity continue to decrease. Can still easily wake the person
what is N3

Insomnia
_________ ________ Sleeping troubles increase with age, with 40% of older adults having sleep problems. REM shortens. There is more light sleep and less deep sleep. Awaken more at night and nap more in the day because of this.
Older Adults
Inability to breathe and sleep at the same time due to lack of airflow through the nose/mouth. This causes the patient to awaken to breathe. Snoring is common. Obstructive, central, or mixed.
sleep apnea
interruption in airflow despite the effort to breathe. The airway becomes partially or completely obstructed.
obstructive sleep apnea (OSA)
involves a dysfunction in the respiratory center of the brain and the impulse to breathe is not sent.
central sleep apnea (CSA)
Mixed?
both OSA and CSA
a type of hypersomnia. A dysfunction in the processes that regulate sleep and wake states. The person will fall asleep uncontrollably at inappropriate times. Often mistaken for laziness, lack of interest, or drunkenness.

hypnotics
temporality
worse
older
diuretics can cause
nocturia

rotating shifts, switching from days to nights can confuse our bodies
lifestyle; daily routines affect out sleep patterns
worrying about situations can make it hard to fall asleep, cause us to wake up frequently during sleep, or sleep too much.
stress
Some foods can ______ sleep. Those that contain L-tryptophan or protein, such as meats, cheese, and milk.
promote
Can affect our ability to fall asleep or stay asleep. Having good ventilation, the type of bed, noise and light levels, and room temperature. Also, if a person is used to sleeping next to someone else, it may be difficult for them to sleep alone. However, sleeping next to someone who keeps moving or snores can also interfere with sleep.
environment
only help with sleep temporarily (1 week), can prevent deep sleep, can cause daytime drowsiness and fatigue, and may worsen sleep apnea in older adults.
Hypnotics
decrease REM and total sleep time
Antidepressants and Stimulants
cause nocturia
Diuretics
Decrease REM and cause daytime drowsiness
Opiates and Anticonvulsants
alter REM and increase sleep time but cause daytime drowsiness
Benzodiazepines
can cause nightmares, insomnia, and awakening from sleep
Beta blockers
Keeping exercise within 2 hrs or more from bedtime can promote sleep. Too close to bedtime can prevent sleep, because the body needs time to cool down and relax. Having too much fatigue can make it difficult to fall asleep.
Exercise/fatigue
Some foods can promote sleep. Those that contain L-tryptophan or protein, such as meats, cheese, and milk
Food and intake
that cause pain, discomfort, anxiety, or depression can cause problems with sleep.
Illnesses
___________ illness can disturb sleep by altering the rhythm of breathing, or causing nasal congestion, sinus drainage, and sore throat. Patients may need to elevate their heads more with shortness of breath related to chronic lung disease.
Respiratory
Patients with ________ _______often experience problems with exchanging oxygen and carbon dioxide when they breathe during sleep. _________ can cause early-morning waking and fatigue.
heart failure
Hypertension
(awakening with sensation to urinate at night) disturbs sleep and makes it difficult to return to sleep.
Nocturia
such as peptic ulcer disease can wake patients at night
GI disorders
the patient will experience rhythmic movements of their feet and legs, which keeps them from rest and sleep
Restless leg syndrome (RLS)
assesses daytime sleepiness, with questions about the patient’s likeliness to be sleepy during specific activities
The Epworth Sleepiness Scale
assesses the quality of the patient’s sleep and their sleep patterns.
Pittsburgh Sleep Quality Index
______ _____ with 10 being the best or most sleep and 0 being the worst or no sleep.
numerical scale
the “best nights sleep” and the “worst nights sleep” at each end, then having the patient point to where their sleep is at on the line.
visual analog scale
Sleep is a __________ experience
subjective
encourage patients to stay physically active during the day. Exercise can help improve sleep; however, make sure it is 2-3 hours before bedtime.
promoting activity
limit disruptions to sleep by dimming the lights, conducting conversations quietly and away from pt rooms, or even providing the pt with a sleep mask and earplugs
Environmental Controls
Provide the patient with hygiene before bed, a fresh gown and linens, and clean/dry dressings, etc. Warm showers/ baths can be relaxing.
promoting comfort
Plan your care to limit sleep interruptions. Cluster your tasks, so that you complete as many as possible at once, instead of constantly going in and out of the room. Schedule as much as possible for waking hours.
Periods of Rest and Sleep
You can reduce pt anxiety and stress by communicating with them about their care. Some pts may require sedatives to manage their anxiety; however, these are for short-term use. The pt should be started on the lowest dose and it should be d/c’s asap. Remember that older adults are more sensitive to their effects.
Stress Reduction
___________ are given to induce sleep, while sedatives are given to calm a pt.
hypnotics
often used to treat sleep problems; however, long-term use of these medications can disrupt sleep. Use cautiously in older adults and children under 12 yrs. Contraindicated for infants under 6 mos. or during pregnancy and breastfeeding.
Benzodiazepines and benzodiazepine-like medications like Ambien
can be used instead of benzodiazepines in older adults
Low-dose trazadone (an antidepressant)
To help prevent symptoms of illness from disturbing the pt’s sleep, time the administration of their medications to control pain, nausea, or other symptoms so that they take effect at bedtime. Also, help position the pt for comfort or semi-fowlers for ease of breathing and reducing acid reflux.
Controlling physiological disturbances
Same interventions as in acute care. Try to limit the time they spend in bed and encourage activities. Serve their meals in the dining room. Suggest they limit daytime naps to 30 minutes or less. Try to get them some exposure to sunlight during the day to help their circadian rhythm.
Promoting comfort for restorative or continuing care
__________ __________ _________helps identify changes caused by sleep disorders and assists you in matching their sleep conditions in the healthcare setting to those in their home.
- Ask them what times they usually go to bed and wake up.
- Ask how much time it takes them to fall asleep and if they do anything special to help them fall asleep?
- Ask them how many times they wake up during the night and what they think the cause may be.
usual sleep pattern
Observe the patient for any behaviors that could result from sleep deprivation (irritability, disorientation, frequent yawning, slurred speech, or even delusions or paranoia with prolonged sleep deprivation)
