    Study Notes

    Improving Sleep Patterns

    • Decreasing noise and dimming lights at bedtime can enhance sleep quality.
    • Administering opioid pain medications may induce sleep but is not a recommended intervention for improving sleep patterns.

    Periodic Limb Movement Disorder (PLMD)

    • Characterized by involuntary, repetitive movements primarily in the legs, rarely in arms.
    • Movements last 0.5-10 seconds, occurring at intervals of 5-90 seconds, leading to poor sleep quality and daytime sleepiness.
    • Diagnosis through detailed history and polysomnography (PSG).
    • Treatment may include:
      • Benzodiazepines like clonazepam to improve sleep quality.
      • Valproic acid to reduce muscle activity.
      • Selegiline and dopamine agonists, though effectiveness in PLMD is less established compared to Restless Legs Syndrome (RLS).

    Circadian Rhythm Disorders

    • Disruptions in the circadian time-keeping system affect sleep-wake cycles and quality of sleep.
    • Jet lag disorder is commonly experienced when crossing at least three time zones; severity correlates with the number of zones crossed.
    • Resynchronization can be aided by melatonin and exposure to daylight.
    • Shift work sleep disorder characterized by insomnia and excessive sleepiness is prevalent among night shift workers.

    Narcolepsy

    • A chronic neurological disorder causing uncontrollable urges to sleep and irregular sleep-wake cycles.
    • Rapid onset of REM sleep with disturbed nighttime sleep is common.
    • Two types: Type 1 with cataplexy (sudden muscle tone loss) and Type 2 without cataplexy.
    • Cataplexy triggered by strong emotions is treated with tricyclic antidepressants and SSRIs.
    • Diagnosis involves history, PSG, and multiple sleep latency tests (MSLTs).
    • Management includes sleep hygiene education, safety precautions, and medications like modafinil, armodafinil, Wakix, Sunosi, and sodium oxybate.

    Parasomnias

    • Unusual behaviors during sleep stages due to CNS activation, often without awareness.
    • Arousal parasomnias occur during NREM sleep, including sleepwalking and sleep terrors.
    • Sleepwalking involves limited awareness and no memory upon waking.
    • Nightmares are distressing dreams typically occurring during REM sleep and treated with various medications.

    Gerontologic Considerations

    • Aging leads to shorter sleep duration, decreased efficiency, and increased awakenings, though sleep quantity doesn’t necessarily change.
    • Insomnia symptoms may be exacerbated by chronic health conditions common in the elderly such as depression and cardiovascular diseases.
    • Increased fall risk and cognitive disturbances are concerns, requiring careful assessment for sleep disorders.
    • Caution advised with sleep medications due to altered metabolism in older adults.

    Special Sleep Needs of Nurses

    • Shifts from day to night can lower job satisfaction, increase stress, and contribute to health issues.
    • Risk of shift work sleep disorder includes insomnia and chronic sleep debt affecting health and patient safety.

    Insomnia Management

    • Education and behavioral strategies are key to treating both short-term and chronic insomnia.
    • Cognitive-behavioral therapy for insomnia (CBT-I) and good sleep hygiene practices, such as regular exercise and limited napping, are essential.
    • Drug therapy for insomnia should be personalized and is generally recommended for short-term use to avoid daytime impairment.

    Sleep-Disordered Breathing (SDB)

    • SDB includes abnormal respiratory patterns like snoring and apnea, leading to disrupted sleep.
    • Obstructive Sleep Apnea (OSA) is the most common form, affecting around 25% of US adults with partial or complete airway obstruction during sleep.### Sleep Overview
    • Defined as a state of unconsciousness with ease of arousal.
    • Vital for maintaining mood, behavior, physical health, and overall survival.
    • Insufficient sleep leads to reduced alertness and functioning.
    • Deprivation occurs when sleep needs are unmet; fragmentation involves frequent awakenings.

    Sleep Disturbances and Disorders

    • Sleep disturbances indicate poor sleep quality influenced by health or environmental factors.
    • Sleep disorders are specific abnormalities like insomnia, obstructive sleep apnea (OSA), and narcolepsy.
    • Often unrecognized, these disorders can severely impact health, safety, and economy.

    Sleep–Wake Cycle

    • Regulated by brain structures including the cerebral cortex, hypothalamus, and thalamus.
    • Wakefulness is influenced by various neurotransmitters; decreased orexin can lead to narcolepsy.
    • Sleep behavior involves sleep-promoting neurons and the hormone melatonin, which regulates wakefulness.

    Circadian Rhythms

    • Governed by the suprachiasmatic nucleus (SCN), creating a 24-hour biological rhythm.
    • SCN acts as the master clock, synchronizing other cellular clocks and regulating sleep-wake cycles.
    • Light exposure serves as the primary time cue, and light therapy can adjust these rhythms.

    Sleep Architecture

    • Characterized by distinct patterns of nighttime sleep, measured via polysomnography (PSG).
    • Comprises two main states: Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM).
    • 4-6 cycles of NREM and REM, lasting 60-110 minutes each, occur throughout sleep.

    NREM and REM Sleep

    • NREM accounts for 75-80% of sleep, divided into three stages (N1, N2, N3).
      • N1: Transition stage with slow eye movements.
      • N2: Dominates the night with decreased heart rate and unique EEG patterns.
      • N3: Deep sleep with delta waves, indicating sleep intensity.
    • REM comprises 20-25% of sleep, associated with vivid dreams and brain activity similar to wakefulness.

    Effects of Sleep Deprivation and Disorders

    • Sleep disturbances in hospitals can lead to decreased total sleep time and disrupted cycles.
    • Can contribute to complications like delirium and delayed recovery.
    • Nurses can create conducive sleep environments and consider sleep-aid medications.

    Insomnia

    • The most prevalent sleep disorder, affecting 1 in 3 adults.
    • Symptoms include difficulty falling asleep, staying asleep, waking too early, and feeling unrefreshed.
    • Divided into short-term (less than 3 months) and chronic insomnia (3 months or more), more common in women and those with lower socioeconomic status.

    Diagnosis of Insomnia

    • Subjective assessments like sleep diaries and comprehensive sleep histories are used.
    • Tools such as the Berlin questionnaire and Epworth Sleepiness Scale help assess related symptoms.

    Sleep Apnea Overview

    • Characterized by significant apneic events, diagnosed using the Apnea-Hypopnea Index (AHI).
    • AHI >5 events/hour with lower oxygen saturation confirms OSA diagnosis.
    • Severe cases may exceed 30-50 events per hour, necessitating management strategies.

    Management of Sleep Apnea

    • Behavioral treatments include positional therapy, weight loss, and avoiding sedatives.
    • Medical devices such as CPAP and BiPAP deliver pressure to maintain airway patency.
    • Surgical interventions aim to enhance upper airway openness, including techniques like UPPP and RFA.

    Nursing Considerations

    • Assess and teach patients about their devices and address barriers to adherence.
    • Hospitalized patients should have their devices assessed and considerations made for medications affecting OSA.
    • Postoperative instructions are crucial for recovery and follow-up studies for effective treatment evaluation.

    Sleep

    • Sleep involves a lack of conscious awareness of surroundings but allows for easy arousal.
    • It is a basic, dynamic, and necessary behavior crucial for mood, behavior, physical functioning, and survival.
    • Insufficient sleep can lead to decreased alertness and health issues.
    • Sleep disorders such as insomnia, obstructive sleep apnea (OSA), and narcolepsy represent unique abnormalities impacting sleep quality.

    Sleep Disturbances and Disorders

    • Sleep disturbances refer to conditions resulting in poor sleep quality, often due to health or environmental factors.
    • Sleep disorders are specific abnormalities affecting sleep quality, often underestimated and associated with significant health, safety, and economic consequences.

    Sleep–Wake Cycle

    • The sleep-wake cycle is regulated by the brain, involving the cerebral cortex, hypothalamus, thalamus, and brainstem.
    • Wakefulness is mediated by ARAS and neurotransmitters that activate the cerebral cortex.
    • Sleep is promoted by hypothalamic neurons and the hormone melatonin, which is affected by light exposure.

    Circadian Rhythms

    • Circadian rhythms are 24-hour biological fluctuations regulated by the suprachiasmatic nucleus in the hypothalamus.
    • Light serves as a strong cue, helping synchronize these rhythms which dictate the sleep-wake cycle.

    Sleep Architecture

    • Polysomnography (PSG) is used to record sleep patterns, which include muscle tone (EMG), eye movements (EOG), and brain activity (EEG).
    • Two main sleep states: Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM), with 4-6 cycles occurring nightly.

    NREM Sleep

    • NREM sleep constitutes 75-80% of total sleep time and is divided into three stages:
      • N1: Transition to sleep; easily awakened.
      • N2: Major sleep stage where heart rate and temperature drop.
      • N3: Deep sleep stage characterized by delta brain waves.

    REM Sleep

    • REM sleep, accounting for 20-25% of sleep, follows NREM and is characterized by brain activity resembling wakefulness, postural muscle inhibition, and vivid dreaming.

    Effects of Sleep Deprivation

    • Sleep deprivation and disorders can lead to significant impairments including fatigue, affecting overall quality of life and recovery, especially in hospital settings.

    Insomnia

    • Insomnia is the most prevalent sleep disorder, affecting approximately one in three adults, characterized by difficulty falling or staying asleep, waking up early, or feeling unrefreshed.
    • Chronic insomnia affects around 10% of Americans, more frequently seen in specific demographics such as women and individuals with lower socioeconomic status.

    Insomnia Diagnosis and Management

    • Insomnia is assessed through self-reported sleep diaries, comprehensive sleep history, and actigraphy.
    • Management includes behavioral strategies, sleep hygiene education, cognitive-behavioral therapy (CBT-I), and, if necessary, drug therapy tailored to individual patterns of insomnia.

    Sleep-Disordered Breathing (SDB)

    • SDB entails abnormal respiratory patterns during sleep, including snoring and apnea, leading to sleep disruptions.
    • Obstructive Sleep Apnea (OSA) is the most common form of SDB, affecting around 25% of adults in the U.S.

    Obstructive Sleep Apnea (OSA)

    • OSA involves upper airway obstruction during sleep, prominent during REM sleep when muscle tone is lowest, resulting in repeated apnea episodes.
    • Key risk factors include obesity, age over 65, larger neck circumference, and gender (more common in males and postmenopausal women).

    Diagnosis and Management of OSA

    • Assessment involves a combination of sleep history, questionnaires (Berlin, STOP-BANG), and PSG for accurate diagnosis.
    • Treatment options include behavioral changes, continuous positive airway pressure (CPAP) devices, surgical interventions to enhance airway patency, and potential use of oral appliances.

    General Considerations

    • Effective management of sleep disorders necessitates a thorough understanding of patient habits, environmental factors, and the careful use of medications.
    • Collaboration with an interprofessional team is crucial for optimizing patient outcomes related to sleep health.

    Sleep Basics

    • Sleep: A state of reduced consciousness, easily aroused, crucial for mood, behavior, and health.
    • Sleep insufficiency impacts alertness and physical functioning, while sleep deprivation refers to inadequate sleep for individual needs.
    • Sleep fragmentation involves frequent awakenings, disrupting overall sleep quality.

    Sleep Disturbances vs. Disorders

    • Sleep disturbances: Conditions that result in poor sleep quality, often caused by health or environmental factors.
    • Sleep disorders: Abnormalities occurring during sleep, including insomnia, obstructive sleep apnea (OSA), periodic limb movement disorders, circadian rhythm disorders, narcolepsy, and parasomnias.
    • Sleep disorders often go unnoticed, leading to serious health, safety, and economic consequences.

    Sleep-Wake Cycle

    • Managed by a network of brain regions, including the cerebral cortex, hypothalamus, thalamus, and brainstem.
    • Wakefulness is influenced by the activation of the cerebral cortex by neurotransmitters; illnesses and medications can impair this process.
    • Orexin (hypocretin) deficiencies in the hypothalamus can lead to narcolepsy.

    Sleep Behavior and Melatonin

    • Sleep-promoting neurons inhibit wakefulness pathways, facilitating sleep.
    • Melatonin, produced by the pineal gland, regulates sleep by responding to light exposure; nighttime light can suppress its production.

    Circadian Rhythms

    • 24-hour biological rhythms are regulated by the suprachiasmatic nucleus (SCN), acting as the body's master clock.
    • Synchronization occurs through light exposure, which is the primary cue for adjusting sleep-wake cycles.

    Sleep Architecture

    • Sleep patterns analyzed through polysomnography (PSG) involving EMG, EOG, and EEG measurements.
    • Two main sleep states: REM (20-25% of sleep, vivid dreams, brain waves similar to wakefulness) and NREM (75-80% of sleep, divided into three stages leading from light to deep sleep).

    NREM Sleep Stages

    • N1: Transition phase with slow eye movements; easy to awaken.
    • N2: Majority of sleep, heart rate, and temperature decrease; identifiable brain wave patterns.
    • N3: Deep sleep (slow-wave sleep) characterized by delta waves, indicating intense sleep.

    Sleep Disorders and Consequences

    • Sleep disturbances in hospitals often lead to delirium, increased pain perception, and delayed recovery.
    • Insomnia is the most prevalent sleep disorder, affecting one in three adults, leading to difficulty in initiating or maintaining sleep.
    • Chronic insomnia affects 10% of Americans, more common in women and those with lower socioeconomic status.

    Insomnia Types and Pathophysiology

    • Short-term insomnia: Occurs at least three nights a week, lasting under three months.
    • Chronic insomnia: Same frequency but lasting three months or longer, with risk factors including behaviors, lifestyle, diet, and mental health conditions.

    Diagnosis of Insomnia

    • Tools: Self-reported sleep diaries, comprehensive sleep history, and actigraphy for monitoring sleep patterns.

    Obstructive Sleep Apnea (OSA)

    • Multifactorial condition characterized by repeated airway closure during sleep; risk factors include obesity, age, neck circumference, and gender.
    • Manifestations include snoring, insomnia, daytime sleepiness, and mood changes.

    Diagnostic and Management Strategies

    • Diagnostic tools include sleep history, Berlin questionnaire, STOP-BANG questionnaire, and Epworth Sleepiness Scale.
    • PSG studies measure various sleep characteristics for accurate diagnosis.
    • Treatment includes behavioral modifications, CPAP machines for severe cases, and surgical interventions to improve airway patency.

    Home Care and Education

    • Emphasis on patient education regarding OSA management, including lifestyle changes and device adherence.
    • Post-operative assessments for surgical treatments focused on airway management and recovery monitoring.

    Conclusion

    • Effective management of sleep disorders is crucial for maintaining overall health and quality of life, necessitating a comprehensive approach to diagnosis and treatment.### Sleep Interventions
    • Decreasing noise and dimming lights at bedtime can significantly improve sleep patterns.
    • Avoid using opioid medications solely for inducing sleep.

    Periodic Limb Movement Disorder (PLMD)

    • Characterized by involuntary, repetitive movements primarily in the legs; can also involve arms and other body parts.
    • Movements last 0.5-10 seconds, occurring in intervals of 5-90 seconds, leading to poor sleep quality and excess daytime sleepiness.
    • Diagnosed through detailed histories and polysomnography (PSG).
    • Treatment includes benzodiazepines (e.g., clonazepam) for sleep quality, valproic acid for reducing muscle activity, and selegiline as a dopaminergic agent.

    Circadian Rhythm Disorders

    • Disruptions in the circadian time-keeping system lead to misalignment with the environment, affecting sleep-wake cycles.
    • Jet lag occurs after crossing three or more time zones; severity increases with the number of zones crossed.
    • Light exposure and melatonin can help resynchronize the body’s rhythms.
    • Common symptoms include insomnia and excessive daytime sleepiness, particularly in shift work sleep disorder.

    Narcolepsy

    • A chronic neurological disorder causing uncontrollable urges to sleep, with periods of REM sleep commencing directly.
    • Associated with the loss of neurons producing orexin; often starts in adolescence or early adulthood.
    • Two types: Type 1 (with cataplexy) and Type 2 (without cataplexy).
    • Cataplexy may be triggered by strong emotions and requires treatment with antidepressants.
    • Management focuses on addressing excessive sleepiness and safety precautions; first-line medications include modafinil and sodium oxybate.

    Parasomnias

    • Involves unusual behaviors during sleep stages or transitions, often resulting in fragmented sleep and fatigue.
    • Arousal parasomnias occur during NREM sleep, including sleepwalking and sleep terrors, characterized by limited awareness of the event.
    • Nightmares typically arise during REM sleep, leading to recall of disturbing dreams.
    • Medications may be prescribed for insomnia in critically ill patients.

    Gerontologic Considerations for Sleep

    • Older adults generally experience shorter sleep durations, decreased efficiency, and more frequent awakenings.
    • Sleep disorders may worsen due to common aging conditions like depression and chronic illnesses.
    • Increased caution is needed for sleep medications due to altered metabolism in older adults, as long-acting benzodiazepines should be avoided.

    Special Sleep Needs of Nurses

    • Alternating shifts can lead to decreased job satisfaction and increased stress levels, contributing to shift work sleep disorder.
    • Permanent night shifts increase the risk of chronic fatigue, impacting both nurse health and patient safety.

    Altered Synchrony

    • Disruption of circadian rhythms can raise morbidity and mortality risks, lead to mood disorders, and result in nursing errors.
    • Increased risk of impaired decision-making and coping abilities impacts overall health and performance in nursing roles.
