Pattern classification of flow limited breathing via acoustic and vibration 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 daytime 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.
