Study Notes

Sleep Cycles Overview

Sleep consists of NREM (Non-Rapid Eye Movement) and REM (Rapid Eye Movement) stages.
A complete sleep cycle lasts about 90 minutes and typically repeats 4-6 times per night.
Age affects sleep patterns and stage duration significantly.

Stages of Sleep

NREM Stage I: Light sleep, transitional phase from wakefulness.
NREM Stage II: Deeper sleep with reduced eye movement and slow brain waves, featuring sleep spindles.
NREM Stage III: Onset of deep sleep marked by slow delta waves.
NREM Stage IV: Deepest stage, crucial for physical recovery and characterized by prominent delta waves.
REM Sleep: Active brain state with rapid eye movements, vivid dreams, and higher physiological activity.

Variability Across Age Groups

Children: Longer deep NREM sleep (Stages III and IV) early in the night for growth. REM sleep duration increases in later sleep cycles.
Young Adults: Around 90-minute cycles with balanced distribution; more deep sleep early and REM sleep later.
Older Adults: Notable reduction in deep sleep (Stage IV), increased time in lighter NREM stages (I and II), and more frequent awakenings.

Importance of Sleep Stages

NREM sleep, especially deep sleep, is vital for physical restoration.
REM sleep is essential for cognitive functions like memory consolidation and mood regulation.

Developmental Factors Affecting Sleep

Sleep needs vary by age; younger individuals require more sleep.
Circadian rhythm shifts affect adolescents, leading to later sleep times.
Older adults may experience changes in sleep architecture, leading to fragmented sleep.

Factors Influencing Sleep Quality

Lifestyle: Diet (e.g., caffeine, alcohol), exercise habits, screen time, and sleep hygiene practices impact sleep quality.
Environmental: Noisy or bright environments can disrupt sleep; dark and cool settings are best for sleep.
Psychological: Stress and anxiety contribute to sleep disturbances, causing difficulty in falling asleep or frequent awakenings.
Medical: Chronic illnesses and certain medications may disrupt normal sleep patterns.

Recommended Sleep Duration by Age

Newborns (0-3 months): 14-17 hours
Infants (4-11 months): 12-15 hours
Toddlers (1-2 years): 11-14 hours
Preschoolers (3-5 years): 10-13 hours
Children (6-13 years): 9-11 hours
Teenagers (14-17 years): 8-10 hours
Young Adults (18-25 years): 7-9 hours
Adults (26-64 years): 7-9 hours
Older Adults (≥65 years): 7-8 hours

Sleep Disorders Overview

Insomnia: Difficulty in initiating or maintaining sleep; can be acute or chronic, often tied to stress, anxiety, or poor sleep hygiene.
Narcolepsy: Characterized by excessive daytime sleepiness and sudden sleep episodes; may include symptoms such as cataplexy and sleep paralysis.
Obstructive Sleep Apnea (OSA): Repeated airway blockages during sleep leading to breathing interruptions; associated with risk factors like obesity.
Restless Legs Syndrome (RLS): Urge to move legs mainly at night, disrupting sleep; linked to dopamine and iron deficiency issues.

Managing Sleep Disorders

Nonpharmacologic Treatments: CBT-I for insomnia, sleep hygiene education, and scheduled napping for narcolepsy.
Medications: Use of stimulants for narcolepsy, benzodiazepines, and non-benzodiazepine hypnotics for insomnia as needed.
Lifestyle Changes: Regular diet, exercise, and a conducive environment for sleep can improve sleep quality.

Illnesses Impacting Sleep

GERD: Causes discomfort and frequent awakenings due to acid reflux.
Coronary Artery Diseases: Associated with sleep interruptions and conditions like sleep apnea.
Liver Failure: Can cause confusion and irregular sleep patterns, complicating sleep quality.
Hypothyroidism and ESRD: Impact sleep due to related symptoms and treatment schedules.

Conclusion

Recognizing factors impacting sleep and disorders is crucial for improving sleep health.
Proper strategies, including good sleep hygiene, medical treatment, and lifestyle adjustments, are essential for enhancing sleep quality and overall well-being.### Obstructive Sleep Apnea (OSA)
OSA is characterized by repeated partial or complete blockages of the upper airway during sleep, resulting in apneas and hypopneas.
Apnea lasts at least 10 seconds and can lead to drops in blood oxygen levels, occurring multiple times per hour.
Hypopnea involves a 30% reduction in airflow with decreased blood oxygen saturation, disrupting sleep.
Symptoms include excessive daytime sleepiness, loud snoring, and observed apneas by sleep partners.
Associated health risks include hypertension, heart disease, obesity, and neurocognitive impairments such as memory loss and decreased concentration.
Diagnosis is typically conducted through polysomnography, which monitors airflow, oxygen levels, and brain activity during sleep.
Treatment options include CPAP therapy, lifestyle changes (weight loss, avoiding sedatives), oral appliances, and surgical interventions if necessary.

Restless Legs Syndrome (RLS)

RLS, or Willis-Ekbom Disease, is a neurological disorder characterized by an irresistible urge to move the legs, often due to uncomfortable sensations that worsen during rest.
Affects up to 15% of the population, primarily middle-aged and older adults, and can severely disrupt sleep.
Symptoms include unpleasant leg sensations described as creeping or tingling, with relief occurring through movement.
RLS can be primary (idiopathic) or secondary, associated with conditions like iron deficiency, pregnancy, and chronic kidney disease.
Nonpharmacologic treatments include lifestyle changes, gentle leg massages, physical activities, and application of hot or cold packs for symptom relief.
Common pharmacologic treatments include dopaminergic agents (pramipexole, ropinirole), anticonvulsants (gabapentin, pregabalin), iron supplements, and sometimes opioids for severe cases.

Circadian Rhythm Sleep-Wake Disorders

These disorders involve chronic disruptions in the sleep-wake cycle, leading to insomnia or excessive sleepiness.
Primary causes include alterations in the internal circadian timing system or misalignments between this internal clock and the external environment.
Specific conditions include Shift Work Disorder, Jet Lag Disorder, Delayed Sleep-Wake Phase Disorder, and Advanced Sleep-Wake Phase Disorder.
Symptoms often cause distress or impairment in daily functioning, including insomnia and excessive sleepiness lasting at least three months.
Management strategies may involve lifestyle modifications, consistent sleep schedules, exposure to natural light, melatonin, or light therapy.

Sleep Hygiene Tips for Better Sleep

Maintain a consistent sleep-wake schedule to regulate the internal clock.
Avoid caffeine and large meals close to bedtime to prevent discomfort and stimulation.
Limit screen time before bed to prevent disruption of melatonin production.
Create a comfortable sleep environment with minimal noise and light.
Engage in regular physical activity but refrain from vigorous exercise near bedtime.
Track sleep patterns using a sleep diary to identify habits and triggers affecting sleep quality.

Obtaining a Sleep History

Key components include the nature of the sleep problem, potential causes, associated symptoms, onset and frequency, daily life impact, severity, and coping strategies.
Identifying how the sleep issue affects quality of life is crucial for developing a tailored treatment plan.

Sleep Characteristics to Assess

Observe restlessness, sleep postures, unusual sleep activities, snoring patterns, and leg jerking to identify underlying sleep disorders.
These characteristics assist in understanding sleep issues and formulating appropriate interventions to improve sleep quality.

Use of Sleep Diary

Track times for retiring, falling asleep, and waking, alongside noting stressors, dietary influences, and physical activities.
Documenting sleep patterns aids in recognizing factors that disrupt sleep, facilitating targeted improvements in sleep health.### Purpose of a Sleep Diary
A sleep diary offers insights into a patient's sleep patterns, habits, and disruptors.
It aids healthcare providers in diagnosing sleep disorders and crafting personalized treatment plans.
Tracking sleep elements allows patients to recognize behaviors impacting sleep quality and make informed improvements.

Nursing Interventions to Promote Sleep

Prepare a Restful Environment:
- Control noise, adjust temperature, and minimize light exposure.
- Ensure comfortable bedding for a conducive sleeping environment.
Promote Bedtime Rituals:
- Encourage consistent bedtime routines such as reading or warm baths.
- Rituals help signal to the body that it's time to unwind for sleep.
Offer Appropriate Bedtime Snacks and Beverages:
- Suggest light snacks like warm milk or herbal tea to promote sleep.
- Avoid caffeine or heavy meals before bedtime as these disrupt sleep.
Promote Relaxation and Comfort:
- Implement relaxation techniques like deep breathing and progressive muscle relaxation.
- Ensure physical comfort through proper support and body alignment.
Respect Normal Sleep-Wake Patterns:
- Schedule activities around the patient's typical sleep hours.
- Avoid waking patients unnecessarily during their usual sleep.
Schedule Nursing Care to Avoid Disturbances:
- Time interventions to minimize disruptions during the patient’s sleep.

Nursing Evaluation for Sleep Interventions

Assess if patients can verbalize feeling rested after sleep, indicating successful intervention.
Patients should identify factors disrupting their sleep, essential for addressing issues.
Demonstration of sleep-promoting techniques and a restful environment reflects adherence to good sleep hygiene practices.
Effective nursing care is shown by improvements in daytime alertness and cognitive function, reducing daytime sleepiness.
Evaluate the reduction of sleep deprivation behaviors, such as irritability or mood swings, and avoidance of stimulants like caffeine.
Continuous assessment and tailored care plans are crucial for maintaining healthy sleep patterns and promoting overall sleep quality.
