Obstructive sleep apnea (OSA) is a chronic condition characterised by frequent episodes of upper airway collapse during sleep. Its effect on nocturnal sleep quality and ensuing daytime fatigue and sleepiness are widely acknowledged.

Risk factors including systemic hypertension, cardiovascular disease, stroke, and abnormal glucose metabolism and cardiovascular death are associated with OSA.

Obstructive sleep apnea is recognised as an important cause of medical morbidity and mortality, however compounding the lack of patient awareness, health care professionals in most medical specialties, and critically within general practice, have no access to a simple screening device.
