Obstructive sleep apnea (OSA) is a common chronic disorder that often requires lifelong care . Cardinal features in adults include:
●Obstructive apneas, hypopneas, or respiratory effort related arousals
●Daytime symptoms attributable to disrupted sleep, such as sleepiness, fatigue, or poor concentration
●Signs of disturbed sleep, such as snoring, restlessness, or resuscitative snorts
OSA is an important disorder because patients are at increased risk for poor neurocognitive performance and adverse medical outcomes, due to repeated arousals and/or hypoxemia during sleep over months to years. The severity and duration of OSA necessary for development of these sequelae vary among individuals . In addition, severe untreated OSA has been associated with increased all-cause and cardiovascular mortality.
