About Sleep-Disordered Breathing

Sleep-disordered breathing (SDB) is characterised by abnormal respiratory patterns, or pauses in breathing, and insufficient ventilation during sleep. 

Some of the most common types of sleep-disordered breathing include upper airway resistance syndrome (UARS), and obstructive sleep apnoea-hypopnea syndrome* (OSAHS), also known as obstructive sleep apnoea (OSA). 

If your patients have sleep-disordered breathing, they are most likely suffering from disrupted sleep, daytime fatigue and a reduced quality of life. But they are not alone: as many as one in five adults has sleep-disordered breathing.1

* An apnoea refers to a pause in respiration lasting more than 10 seconds. A hypopnoea is defined as a decrease in airflow of at least 30% for 10 seconds or more, with an associated oxygen desaturation or arousal.
