Objective: To evaluate, industry independently, the accuracy of the Watch-PAT100 system (WP100) [Itamar Medical; Caesarea, Israel], a portable home sleep test, compared to polysomnography, the gold standard for diagnosing obstructive sleep apnea syndrome. Methods: Prospective clinical trial. 27 patients (24 male, 3 female) were evaluated at our institution's sleep laboratory. The apnea hypopnea...

BACKGROUND AND OBJECTIVES Obstructive sleep apnea is associated with significantly increased cardiovascular morbidity and mortality. Fluid overload may promote obstructive sleep apnea in patients with ESRD through an overnight fluid shift from the legs to the neck soft tissues. Body fluid shift and severity of obstructive sleep apnea before and after hemodialysis were compared in patients with ...

Obstructive sleep apnea syndrome (OSAS) is a common clinical condition. The way that OSAS risk factors associate and converge is not a random process. As such, defining OSAS phenotypes fosters personalized patient management and population screening. In this paper, we present a network-based observational, retrospective study on a cohort of 1,371 consecutive OSAS patients and 611 non-OSAS contr...

BACKGROUND Previous studies have suggested that the obstructive sleep apnea syndrome may be an important risk factor for stroke. It has not been determined, however, whether the syndrome is independently related to the risk of stroke or death from any cause after adjustment for other risk factors, including hypertension. METHODS In this observational cohort study, consecutive patients underwe...

STUDY OBJECTIVES Identify polysomnographic and demographic factors associated with elevation of nocturnal end-tidal CO2 in patients with obstructive sleep apnea. METHODS Forty-four adult patients with obstructive sleep apnea were selected such that the maximal nocturnal end-tidal CO2 was below 45 mm Hg in 15 studies, between 45 and 50 mm Hg in 14, and above 50 mm Hg in 15. Measurements includ...

BACKGROUND The currently available polysomnography (PSG) equipments and operating personnel are facing increasing pressure, such situation may result in the problem that a large number of obstructive sleep apnea (OSA) patients cannot receive timely diagnosis and treatment, we sought to develop a nomogram quantifying the risk of OSA for a better decision of using PSG, based on the clinical syndr...

BACKGROUND Sleepiness-at-the-wheel has been identified as a major cause of highway accidents. The aim of our study is identifying the candidate measures for home-based screening of sleep disordered breathing in Taiwanese bus drivers, instead of polysomnography. METHODS Overnight polysomnography accompanied with simultaneous measurements of alternative screening devices (pulse oximetry, ApneaL...

OBJECTIVE To determine the prevalence, distribution and determinants of newborn apnea in a resource-constrained setting. DESIGN Retrospective study. MATERIALS AND METHODS Newborn babies who had apnea during hospitalization between January and December 2008 were studied. The sex, age and body weight, clinical conditions, etiologies of apnea and outcome were recorded. Babies with and without ...

BACKGROUND The Hoffstein formula is the most widely used equation to predict optimal CPAP pressure in patients with obstructive sleep apnea, but it is based on data from white patients. The purpose of this study was to develop an equation for optimal CPAP based on data from Asian patients, and to compare this new formula with the Hoffstein formula. METHODS We retrospectively reviewed the reco...
