Pattern classification of flow limited breathingvia acoustic measurements

Snoring during sleep is common and is sometimes indicative of a mechanical impediment to
breathing. The condition, called high upper airway reSistance, is thought to be relatively
common affecting roughly 15% of the population. It is characterized by complaints of day1ime
fatigue and/or sleepiness and is associated with a myriad of disastrous effects on a patient’s
health such as high blood pressure, depression, atrial fibrillation, migraine, bruxism,
temporal-mandibular jOint disorders, fibromyalgia and chronic fatigue syndrome. The exact
incidence of HUAR is unknown with the majority of patients undiagnosed and left untreated.
The principal reason for this is the lack of a convenient, non-invasive method for making the
diagnosis of HUAR. The proposed research will use a complex analysis of snoring sound to
identify the occurrence and distinguish it from simple snoring.
