    Study Notes

    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.

    Patient Interaction

    • Nurse's supportive response to patient experiencing job loss: "Can you tell me more about what is happening in your life?"

    Insomnia Management

    • Goals: Prevent short-term insomnia from becoming chronic and treat chronic insomnia.
    • Education on sleep hygiene is crucial for quality sleep and daytime alertness.
    • Cognitive-behavioral therapy for insomnia (CBT-I) recommended.
    • Suggestions include limiting naps to 15-20 minutes, regular exercise, and avoiding exercise close to bedtime.

    Drug Therapy for Insomnia

    • Individualized for specific insomnia patterns; typically short-term treatment.
    • Risk of daytime impairment and potential for dependence on over-the-counter medications.
    • Rebound insomnia may occur when stopping certain sleep medications abruptly.

    Types of Sleep Medications

    • Benzodiazepine-receptor agonists suitable for intermittent use for sleep onset and maintenance.
    • Orexin-receptor antagonist helps with sleep initiation and maintenance issues.
    • Melatonin receptor agonists aid in falling asleep but may not be effective for waking during the night.
    • Some tricyclic antidepressants have sedative side effects, but benzodiazepine hypnotics are not first-line therapies due to sedation risks when combined with alcohol or CNS depressants.

    Complementary Therapies

    • Melatonin is effective for circadian rhythm disorders but not recommended solely for insomnia.
    • Herbal remedies require further clinical testing for efficacy.

    Assessment for Insomnia

    • Evaluate personal habits and environmental factors impacting sleep.
    • Inquire about diet, caffeine intake, and use of sleep aids.
    • Sleep diary, medical history, including mental and physical health, is essential.
    • Consider effects of shift work and travel on sleep patterns.

    Sleep-Disordered Breathing (SDB)

    • Characterized by abnormal respiratory patterns during sleep, including snoring, apnea, and hypopnea.
    • Causes sleep disruptions and may lead to obstructive sleep apnea (OSA), affecting about 25% of U.S. adults.

    Obstructive Sleep Apnea (OSA)

    • OSA involves upper airway obstruction during sleep, especially during REM sleep.
    • Defined by apneic events (>90% cessation of airflow for >10 seconds) and hypopnea (30-90% decrease in airflow).

    Risk Factors for OSA

    • Significant factors include obesity (BMI > 30), age over 65, neck circumference >16 inches, male gender, and postmenopausal women.

    Manifestations of OSA

    • Symptoms include frequent arousals, excessive daytime sleepiness, insomnia, witnessed apneas, snoring, morning headaches, irritability, and personality changes.

    Consequences of Untreated OSA

    • Serious health risks include hypertension, type 2 diabetes, dysrhythmias, coronary heart disease, arteriosclerosis, and heart failure.

    Diagnostic Studies for OSA

    • Medical history and specific questionnaires like Berlin and STOP-BANG assess risk.
    • Epworth Sleepiness Scale evaluates sleepiness levels.

    Polysomnography (PSG)

    • Comprehensive sleep study measures sleep stages, airflow, oxygen levels, and limb movements.

    Apnea-Hypopnea Index (AHI)

    • AHI indicates severity of OSA with >5 events/hour required for diagnosis; severe cases may show >30-50 events/hour.

    Management Approaches for OSA

    • Behavioral treatments: positional therapy, elevating head while sleeping, and weight loss.
    • Continuous Positive Airway Pressure (CPAP) indicated for severe cases, though adherence may be challenging due to nasal issues.

    Surgical Interventions for OSA

    • Uvulopalatopharyngoplasty (UPPP) and genioglossal advancement enhance airway patency.
    • Radiofrequency ablation (least invasive), and neurostimulators (under investigation) are also options.
    • Postoperative complications include airway obstruction; follow-up PSG recommended after surgery.

    Case Study Implementation

    • Assess patient knowledge regarding OSA treatments and involve bed partners in education.
    • Encourage adherence to therapy and monitor for medications that may exacerbate symptoms.### 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.

    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
