Comparison of STFT and CWT for Normal subjects and OSA patient
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Obstructive sleep apnea (OSA) is a potentially serious sleep disorder and is caused by obstruction in the upper airway in the presence of the breathing effort. It is characterized by recurrent episodes of upper airway (UA) collapse during sleep due to intermittent relaxing and blocking of the patients airway by the throat muscle. Here noninvasive method of screening OSA patients is proposed. The tracheal breathing sound of the patients with and without obstructive sleep apnea were recorded using the low cost sensor during wakefulness in the supine position. In this study short time Fourier transform (STFT) and continuous wavelet transform (WT) is applied on breathing signal obtained from the normal subject and OSA patient.
