sleep-disordered breathing
Also written as: SDB — Sleep-Disordered Breathing
An umbrella term for abnormal respiratory patterns during sleep, including apneas and hypopneas.
Full Definition
Sleep-disordered breathing (SDB) encompasses a spectrum of abnormal respiratory patterns that occur during sleep, ranging from simple snoring to severe obstructive sleep apnea. This category includes obstructive sleep apnea, central sleep apnea, mixed sleep apnea, and upper airway resistance syndrome. SDB is characterized by recurrent episodes of partial or complete upper airway obstruction, abnormal ventilatory control, or increased respiratory effort during sleep. The severity and clinical significance vary widely, but all forms can potentially affect sleep quality, daytime function, and long-term health outcomes.
Usage
Usage note: Hyphenate as compound term; broader category than specific apnea types.
