Q

43
Respiratory & sleep problems - sleep apnea - snoring and hypoventilation - obesity hypoventilation syndrome - reduced chest wall compliance - increased work of breathing - deceased total lung capacity and functional residual capacity - also called obstructive sleep apnea hypopnea syndrome ( OSAHS ) - partial/ complete upper airways obstruction during sleep - apneic period may include hypoxemia & hypercapnia

44
Respiratory & sleep problems: complications can result in - hypertension - cardiac changes - poor concentration/ memory - impotence - depression
Hypertension Cardiac changes Poor concentration/ memory Impotence Depression
45
Clinical signs and symptoms - apnea is cessation of spontaneous respirations for longer than 10 s - each obstruction may last from 10 to 90 s - apnea and arousal cycles occur repeatedly, as many as 200 to 400 x during 6 to 8 hrs of sleep
Frequent arousal during sleep Insomnia Excessive daytime sleepiness Witnessed apneic episodes Loud snoring Morning headache Irritability
46
Risk factors Sleep apnea occurs in 2 to 10% of Americans but us considered to be underreported - obesity - age >65 yo - neck circumference >17 inches - craniofacial abnormalities that affect the upper airway and acromegaly - smokers are more likely to have OSA - OSA is more common in men than in woman until after menopause, when the prevalence of the disorder is the same in both genders. Women with OSA have higher mortality rates
- obesity (bmi >28 kg/m2) - age >65 yo - neck circumference >17 inches - craniofacial abnormalities that affect the upper airway and acromegaly - smokers are more likely to have OSA - OSA is more common in men than in woman until after menopause, when the prevalence of the disorder is the same in both genders. Women with OSA have higher mortality rates OSA IS SLEEP APNEA
47
Lab & diagnostic testing - may take one or two nights for complete diagnosis depends - polysomnography AKA SLEEP STUDY

Explain benefit of losing weight Explain benefit of sleeping on side Explain the need to avoid sedatives or alcohol 3-4 hrs before bedtime Stress reduction Stress importance of exercise Avoid smoking Self imagine disturbance
51
Discharge planning - case manger need for equipment - nutritional consult - spiritual consult
Case manger need for equipment Nutritional consult Spiritual consult
52
Nursing diagnosis - anxiety - insomnia - imbalanced nutrition more than body requires - knowledge deficit
Anxiety Insomnia Imbalanced nutrition more than body requires Knowledge deficit
53
Narcolepsy - brain unable to regulate sleep wake cycles normally - causes uncontrollable urges to sleep, often fo directly into REM sleep - unknown cause
Unknown cause - associated with destruction of neurons that produce orexin - orexin - neuropeptide that regulates sleep/ wake cycles - low lvls of orexin lead to difficulty staying awake
54
Narcolepsy 2 types: - type 1: with cataplexy - type 2: without cataplexy Symptoms - sleep paralysis - cataplexy - fragmented nighttime sleep
Narcolepsy = immediate deep sleep, diagnosed based sleep study 2 types: - type 1: with cataplexy - type 2: without cataplexy ( no muscle weakness ) Symptoms - sleep paralysis - cataplexy ( muscle weakness ) - fragmented nighttime sleep ( can last longer than an hr )
55
Narcolepsy Nursing & interprofessional management - teach abt sleep & sleep hygiene - take naps - avoid heavy meals and alcohol - ensure pt safety - lifestyle changes

58
Gerontological Considerations - older age is associated with — overall shorter total sleep time — decreased sleep efficiency — more awakenings — insomnia symptoms
Older age is associated with - overall shorter total sleep time - more awakenings - insomnias symptoms
59
Gerontological considerations Sleep - awakenings during the night increases risk for falls - medications used by older adults can contribute to sleep problems - avoid long acting benzodiazepines
Awakenings during the night increases risk for falls Medications used by older adults can contribute to sleep problems Avoid long acting benzodiazepines
60
Nurse fatigue: Facts - inadequate sleep - extended work hours - increased risk for errors
Inadequate sleep Extended work hours Increased risk for errors
61
Who is at risk? - nurse compassion fatigue - pts - nurse — awake for 17 hrs — awake for more than 24 hrs
Nurse - Awake for 17 hrs — equals same cognition as blood alcohol lvl 0.05% - Awake for more than 24 hrs — equivalent to blood alcohol lvl 0.10%
62
National academy of medicine - Formerly institute of medicine — nonprofit organization devoted to safety and evidence based practice in healthcare - recommendations — no more than 12 hrs in 24 hr period — limit to 60 hrs in one week
Formerly institute of medicine - nonprofit organization devoted to safety & evidence based practice in healthcare Recommendations - no more than 12 hrs in 24 hr period - limit to 60 hrs in one week
63
Nurse fatigue: management Do’s Don’ts
Do’s - take at least 1 break in addition to lunch break - use caffeine therapeutically as a stimulant to stay awake - nutrition: complex cards and protein - exercise Don’ts - DO NOT DRINK ALCOHOL ( DEPRESSANT )
64
Shift work sleep disorder Characterized by - insomnia - excessive sleepiness
Insomnia Excessive sleepiness
65
Shift work sleep disorder symptoms include - fatigue or malaise - difficulty paying attention or concentrating - memory impairment - mood disturbance or irritability - excessive daytime sleepiness - hyperactivity impulsivity aggression and other behavioral problems - reduced motivation energy or initiative - feeling of sleep dissatisfaction
Fatigue or malaise Difficulty paying attention or concentrating Memory impairment Mood disturbance or irritability Excessive daytime sleepiness Hyperactivity impulsivity aggression and other behavioral problems Reduced motivation energy or initiative Feeling of sleep dissatisfaction
