Alshaer H, Fernie GR, Tseng WH, Bradley TD, Sleep Medicine. 2015; 15:2041 The objectives of this study were to: 1) test the validity of BresoDX, a portable sleep apnea monitoring system, for determining the apnea-hypopnea index (AHI) versus that derived from simultaneous polysomnography (PSG), [...]

Alshaer H, Fernie GR, Maki E, Bradley TD, Sleep Medicine. 2013; 14:562. The objective of this study was to test the validity of a single-channel portable monitoring system that captures breath sounds (BSs) during sleep on a microphone that is embedded in a face-frame and written on to a [...]

Yadollahi A, Alshaer H, Radfar H, Bradley TD. Conf Proc IEEE Eng Med Biol Soc. 2012; 3648. Abstract Respiratory sound analysis is a simple and noninvasive way to study the pathophysiology of the upper airway (UA). Recently, it has been used to diagnose partial or complete UA collapse in [...]

Alshaer H, Rudzicz F, Falk T, Tseng WH, Bradley TD. 35th IEEE EMBS Conference, Osaka, Japan  July 3-7, 2013; 2080. Abstract Upper airway (UA) narrowing and collapse during sleep results in obstructive sleep apnea (OSA). We hypothesize that vibratory patterns of snoring can distinguish simple [...]

Alshaer H, Levchenko A, Bradley TD, Pong S, Tseng WH, Fernie GR. J. Clin. Monit. Comput. 2013; 27:303. We studied 49 subjects who used a portable device (BresoDX) at home of whom 32 also had simultaneous PSG on another night. 11 also had a second home test. There was a strong relationship [...]

Hummel R, Bradley TD, Fernie GR, Chang SJ, Alshaer H, Conf. Proc. IEEE Eng. Med. Biol. Soc. 2015, 5416. We tested an actigraph embedded in a portable device, BresoDX, to measure head motion to detect sleep/wake state in 75 patients with sleep apnea (SA) vs simultaneous PSG. The results show [...]
