ABSTRACT
Sleep-disordered breathing encompasses a wide variety of disorders characterized by abnormal nocturnal respiration, including snoring, obstructive sleep apnea (‘‘sleep apnea’’), upper airway resistance syndrome, central sleep apnea, central hypoventilation, and other nonobstructive hypoventilation disorders. For the purposes of this chapter, sleep-disordered breathing and obstructive sleep apnea will be used interchangeably.
