Hilbert Huang analysis of the breathing sounds of obstructive sleep apnea patients and normal subjects during wakefulness

Obstructive sleep apnea is a sleep related breathing disorder that occurs when the muscles relax during sleep, caused by the collapse of the soft tissues at the back of the throat and blocks the upper airway that increases the risk for several cardiovascular diseases. In this paper, a non-invasive method for screening patients with Obstructive Sleep Apnea (OSA) is proposed. The tracheal breath sound of the subjects was recorded in supine position, during wakefulness, and Hilbert Huang Analysis was performed. The differences between the output spectrums of OSA patients and other subjects enable the diagnosis of OSA with increased accuracy.
