SLEEP , COMFORT

1. SLEEP , COMFORT

2. REST • When people are at rest, they usually feel mentally relaxed, free from anxiety, and physically calm • Rest does not imply inactivity

3. SLEEP • Sleep is a recurrent, altered state of consciousness that occurs for sustained periods • Sleep is a cyclical physiological process • Circadian rhythm • Biological clocks

4. Sleep Regulation • Sleep involves a sequence of physiological states maintained by the CNS • RAS ( reticular activating system) = wakefulness & BSR (bulbar synchronizing region) = sleep

5. STAGES OF SLEEP • NREM sleep = nonrapid eye movement - involves 4 stages • REM sleep = rapid eye movement

9. Stage 1: NREM • Lightest level of sleep • Lasts a few minutes • Easily aroused by sensory stimuli • Waken, person feels as though daydreaming has occurred

10. Stage 2: NREM • Period of sound sleep • Relaxation progresses • Arousal is still relatively easy • Stage lasts 10-20 minutes • Body functions, vital signs & metabolism, slow

11. Stage 3: NREM • Involves initial stages of deep sleep • Sleeper is difficult to arouse and rarely moves • Muscles are completely relaxed • Lasts 15-30 minutes

12. Stage 4: NREM • Very difficult to arouse sleeper • Deepest stage of sleep • If sleep loss has occurred, sleeper will spend considerable portion of night in this stage • Vital signs are significantly lower than during waking hours • Lasts approximately 15-30 minutes • Sleepwalking and enuresis may occur

13. Vivid, full-color dreaming may occur in REM. Usually begins about 90 minutes after sleep has begun Typified by autonomic response of rapidly moving eyes, fluctuating heart and resp rates, increased BP Loss of skeletal muscle tone occurs Gastric secretions increase Very difficult to arouse Duration of REM sleep increased with each cycle and averages 20 minutes REM SLEEP

14. Functions/Purpose of Sleep • Restoration • Psychological • Physiological • Biological • Cognitive • Conservation of energy

15. FACTORS THAT AFFECT SLEEP • Physical illness • Drugs and substances • Lifestyle • Emotional stress • Environment • Exercise and fatigue • Food and caloric intake

16. SLEEP DISORDERS • INSOMNIA • SLEEP APNEA • NARCOLEPSY • SLEEP DEPRIVATION • PARASOMNIAS

17. INSOMNIA • Chronic difficulty falling asleep • Frequent awakenings from sleep • Short sleep or nonrestorative sleep

18. SLEEP APNEA • Disorder in which the individual cannot breath and sleep at the same time • Lack of airflow through the nose and mouth for periods from 10 seconds to 1-2 minutes, there can be 10 or 15 to more than 100 respiratory events per hour of sleep • Three types: central, obstructive, and mixed

19. CENTRAL SLEEP APNEA • Caused by cessation of diaphragmatic and intercostal respiratory effort as a result of dysfunction of the brain’s respiratory control center • Impulse to breath fails, temporarily • Least common form

20. OBSTRUCTIVE APNEA • Most common form • Characterized by cessation of airflow despite the effort to breath • Occurs when muscles or structures of the oral cavity or throat relax during sleep • Usually have loud snoring

22. NARCOLEPSY • A CNS dysfunction of mechanisms that regulate the sleep and wake states • Falls asleep uncontrollably at inappropriate times • Treated with stimulants

23. SLEEP DEPRIVATION • S/S: blurred vision, fine motor clumsiness, decreased reflexes, slowed response time, decreased reasoning and judgment, cardiac arrhythmias • Psychological S/S: confusion, disorientation, increased sensitivity to pain, irritable, withdrawn, agitation, decreased motivation

24. PARASOMNIAS • Sleep problems that are more common in children, one common exception is bruxism (tooth grinding) • SIDS • Somnambulism(sleepwalking) • Nightmares • Nocturnal enuresis (bedwetting)

25. ASSESSMENT • Normal sleep pattern, restful? sufficient? • Self- reported • Sleep log • Bedtime routines • Bedtime environment • Client expectations

26. Pain • Physical sensation • Involves physical, emotional and cognitive components • Stimulus

27. Physiology of Pain • Transduction • Transmission • Perception • Modulation

29. Types of Pain • Acute • Chronic • Idiopatic • Inferred • nociceptive • neuropatic

30. Pain Assessment • Scales • Nonverbal pain indicators • Behavioral indicators

31. Pain Management • Pharmacological interventions • Non-pharmacological interventions • Barriers • Cultural considerations • Reassessment

32. Environmental factors affecting common and sleep • Comfortable room temperature • Proper ventilation • Minimal noise • Comfortable bed • Proper lighting

33. Promoting Bedtime Routines • Help client to relax in preparation for sleep • Avoid mental stimulation before bedtime • Relaxation exercises • Guided imagery • Good sleep hygiene

34. Sleep Hygiene • Avoid sleeping long hours during weekend or holiday • Bedroom should not be used for intensive studying, snacking, TV watching, or other nonsleep activity • Avoid worrisome thinking when going to bed • Avoid heavy meals for 3 hours before bedtime

37. Promoting comfort • Encourage client to wear loose-fitting nightwear • Instruct family on ways to position client and support dependent body parts to aid in muscle relaxation • Have client void before going to bed • Back massage • Keep bed linens dry

38. Activity • If client is at home, encourage physical activity during daytime • Avoid rigorous exercise at least several hours before bedtime

39. Control of noise in hospital • Close doors to client’s room • Keep doors to work areas closed • Reduce volume of nearby telephones and paging equipment • Avoid abrupt loud noises • Keep necessary conversations at low levels
