Final Terms Flashcards
What is Sleep?
Sleep is a naturally recurring state and a universal experience across all cultures
Circadian Clock
regulates hormones and temperatures during sleep resulting in effective or restful sleep.
Internal clock
regulates the “perfect” amount of sleep a person needs for best functioning
Sleep Deprivation/Sleep debt
owes” sleep hours towards rest
REM sleep:
sleep that occurs at intervals during the night and is characterized by rapid eye movements,
** more dreaming and bodily movement, and faster pulse and breathing.
Non REM (NREM) sleep:
sleep is dreamless* sleep. During NREM, the brain waves on the electroencephalographic (EEG) recording are typically slow and of high voltage,
**breathing and heart rate are slow and regular, the blood pressure is low, and the sleeper is relatively still.
Acute Stress:
body stress is normal important for survival; adrenaline cortisol is released; can affect bodies ability to calm down and sleep
Chronic Stress:
long exposure to stress; hippo campus functions poorly, accelerated neuron death
Insomnia
sleep disorder that is characterized by difficulty falling and/or staying asleep. People with insomnia have one or more of the following symptoms: Difficulty falling asleep. Waking up often during the night and having trouble going back to sleep
Psychophysiological insomnia (Conditioned insomnia)
individuals say that can’t sleep in a certain room or bed or they may avoid it- but object has noting to do with their insomnia
Stimulus Control Therapy
de-conditioning, break cycle of problems
(go to bed when sleepy, use the bed only for sleeping, don’t lay in the bed and can’t sleep; awaken the same time/avoid napping)
Sleep Restriction Therapy
increase sleep efficiency , decrease amount of time lying in bed, be aware of daytime sleepiness, don’t sleep at other times of the day,
Relaxation Therapies
Progressive relaxation, Guided imagery (don’t do with pt who experiences hallucinations), Deep breathing
Biofeedback:
use physiologically marks to increase self-awareness
Cognitive Training:
targets negative emotional thoughts
Hypersomnolence Disorder
Excessive sleepiness that is serious, debilitating, and can be life threatening
Narcolepsy
Sleep attacks of irresistible sleepiness leading to 10-20 min of sleep, feel refreshed briefly
Obstructive Sleep Apnea Hypopnea
Repetitive collapse of the upper airway during sleep
Results in reduced oxygen and transient arousal then respiration resumes
Central Sleep Apnea
Occur in elderly, absence of breathing due to lack of respiratory effort, Like OSA but NO breathing is seen in abdominals or chest
Idiopathic central sleep apnea
high CO2 in arteries, low CO2 in veins, daytime sleepiness, wake up with shortness of breath
Cheyne-Stokes breathing
prolong hyper-pena, alternating with apena, hypo-pena, respiratory rate changes fast to slow to absent seen in older man with CHF or stroke
Central sleep apnea co-morbid with opioid use
causes impairment of neuro-muscular respiration
Circadian Rhythm Sleep-Wake Disorders: Delayed sleep phase type
natural biological clocks run slower, more alert in the evening, more tired in the morning (night owl)
Circadian Rhythm Sleep-Wake Disorders: Advanced sleep phase type
shifts earlier, wake earlier, tired in the evening, early bird
