Vital Signs During Sleep

  • Pulse, Respiratory Rate, Blood Pressure, and Temperature:

    • In sleep, these vital signs decrease, indicating a state of restfulness.

    • Heart rate example: a person's heart rate may lower from around 60 bpm to the 50s during sleep.

  • Deep Tendon Reflexes:

    • These reflexes are often depressed during sleep to keep the body calm and prevent involuntary movements such as kicking.

Stages of Sleep

  • Sleep Stages:

    • N1 (Stage 1):

      • Initial stage of falling asleep; characterized by light sleep.

      • May include jerky movements that can wake the person up.

    • N2 (Stage 2):

      • More stable sleep; person can still be aroused but with more difficulty than N1.

      • Significant decreases in pulses and body functions occur during this stage.

    • N3 (Stage 3):

      • Also known as slow-wave sleep; this phase is very restful.

      • Characterized by a marked decrease in brain and muscle activity.

    • REM Sleep:

      • Occurs after N3; essential for cognitive restoration.

      • Dreaming typically occurs during this stage; brain is active, but the body remains immobile to prevent acting out dreams.

Sleep Cycles

  • Sleep occurs in repeated cycles during the night, lasting about 90 to 120 minutes each.

  • Each cycle includes progression through N1, N2, N3, and REM sleep.

  • Awakening during N2 sleep is easier than from N3, and someone will be less aware of their surroundings if awakened from N3.

Sleep Throughout the Lifespan

  • Infants and Toddlers:

    • Require extensive amounts of sleep but in shorter periods; generally sleep a lot.

  • Preschoolers:

    • Sleep longer at night.

  • Adolescents:

    • Need about 8-10 hours of sleep but may not get enough due to busy schedules.

  • Older Adults:

    • Require less sleep but still need quality sleep; often face disturbances that affect sleep.

Factors Affecting Sleep

  • Environmental Factors:

    • Comfortable temperature and low light are conducive to sleep.

    • Excess noise and light can disrupt sleep.

  • Rituals Before Sleep:

    • Establishing a consistent bedtime routine can promote better sleep.

    • Activities like reading or meditative practices may help calm the mind.

  • Combatting Anxiety:

    • Techniques like deep breathing or distraction can help reduce anxiety and promote sleep.

  • Diet and Substances:

    • Caffeine, heavy foods, and certain medications can negatively impact sleep quality.

    • Alcohol may induce sleep but cause disturbances later in the night.

  • Medications:

    • Some medications, including benzodiazepines, can help with sleep but should not be used long-term.

    • Opioids and beta-blockers can also influence sleep patterns negatively.

Sleep Disorders

  • Insomnia:

    • Difficulty falling/staying asleep can be acute or chronic.

    • Treatment options include lifestyle changes and medication options like Ambien.

  • Narcolepsy:

    • Characterized by sudden and uncontrollable sleep episodes.

    • Often prescribed stimulant medications.

  • Sleep Apnea:

    • An indication of breathing problems during sleep; often diagnosed with a sleep study.

    • CPAP therapy is a common treatment.

  • Restless Leg Syndrome:

    • Creates uncomfortable sensations in the legs leading to an urge to move; often managed with lifestyle and nutritional changes.

  • Parasomnias:

    • Involves abnormal behaviors during sleep, such as sleepwalking and night terrors.

Screening & Assessment of Sleep

  • Primary Prevention:

    • Involves establishing healthy sleep techniques before sleep issues arise.

  • Secondary Prevention:

    • Involves screening with tools like the Pittsburgh Sleep Quality Index and sleep diaries to assess sleep patterns.

  • Tertiary Prevention:

    • Addresses existing sleep problems with therapeutic measures and possibly pharmacological intervention.

Safety in Sleep Environment

  • Reducing Environmental Risks:

    • Minimize noise during nighttime in care facilities.

    • Consider using gentle lighting for older adults needing to get up during the night.

    • Assess patient furniture and assistive devices, ensuring they are safe and accessible.

Fall Risks and Prevention

  • Recognize that previous falls are strong indicators of future fall risks.

  • Utilize appropriate assessment tools, such as the timed up and go test to assess mobility and balance, especially in older adults.

  • Engage in preventative measures like mobility assistance and installations, such as grab bars or non-skid footwear.

Nursing Responsibilities

  • Ensure assessment and intervention plans are in place to minimize fall risk and improve sleep quality in patients.

  • Understand medication effects on sleep and adjust plans accordingly.

  • Engage patients in self-care and preventive measures for better sleep and health outcomes.
