sleep wake disorders Flashcards
The repeated absence of breath with five or more central apneas per hour due to the temporary loss of ventilatory effort related to instability in the body’s feedback mechanisms that control respirations.
central sleep apnea
Biochemical, physiological, and behavioral processes that are driven endogenously, spanning a 24-hour cycle.
circadian rythm
Inability to maintain wakefulness during the day; a score greater than 10 on the Epworth Sleepiness Scale.
excessive daytime sleepiness
A state of physical and/or mental weariness or exhaustion, lethargy.
fatigue
The most common sleep disorder in adults; characterized by repeated difficulty with sleep initiation, duration, consolidation, and/or quality that occurs despite adequate time and opportunity for sleep and results in some form of daytime impairment.
insomnia
A disorder of the wakefulness system, whose key symptom is excessive daytime sleepiness/sleep attacks caused by the intrusion of REM sleep into wakefulness.
narcolepsy
Recurrent absence of breath for five or more times per hour, accompanied by nocturnal breathing problems such as snoring or breathing pauses and daytime sleepiness or fatigue due to collapse or obstruction of the lower posterior pharynx.
obstructive sleep apnea-hypopnea
The structure of stages (1, 2, 3) and phases (REM and NREM) of sleep.
sleep architecture
Measure that includes sleep latency (minutes to get to sleep), minutes awake during the night, sleep efficiency (total sleep time/minutes in bed x 100), and number of awakenings from sleep.
sleep continuity
The presence of partial or complete airway obstruction or dysfunction of the central drive to breath that occurs during sleep.
sleep-disordered breathing
Length of time it takes an individual to fall asleep.
sleep latency
Difficulty maintaining wakefulness.
sleepiness
is diagnosed when testing shows episodes of decreased respiration coupled with elevated CO2 levels (APA, 2013).
sleep-related hypoventilation
