BACKGROUND: In moderately to severely obese patients with obstructive sleep apnea (OSA), the effects of long-term positive airway pressure (PAP) treatment on cardiovascular risk are poorly defined. PURPOSE: To assess the effect of continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) on the occurrence of cardiovascular events in obese OSA patients. METHODS: We performed a noninterventional observational study in obese OSA patients recruited between 2007 and 2010 at the Sleep Center, University of Grenoble, treated with CPAP or NIV, and followed for 5...

BACKGROUND: Cardiorespiratory polysomnography (PSG) is considered the reference method for diagnosis of obstructive sleep apnea (OSA). Due to waiting times and high costs, payers increasingly request outpatient polygraphy (PG) as an alternative to inpatient PSG. The aim of the present study was to evaluate the diagnostic accuracy of different outpatient PG devices compared to stationary PSG in clinical practice. MATERIALS AND METHODS: Externally collected outpatient PG findings of 406 patients were retrospectively compared with the corresponding PSG findings...

PURPOSE: Negative expiratory pressure (NEP) is a simple technique for the evaluation of upper airway collapsibility in patients with obstructive sleep apnea (OSA). Most studies evaluated NEP using a mouthpiece that may exclude the cephalic portion of the upper airway. We hypothesize that NEP determination is influenced by interface and position. METHODS: We evaluated patients with suspected OSA using polysomnography, NEP (-5 cmH2O in sitting and supine position with mouthpiece and nasal mask)...

INTRODUCTION: Obstructive sleep apnea causes changes in normal sleep architecture, fragmenting it chronically with intermittent hypoxia, leading to serious health consequences in the long term. It is believed that the occurrence of respiratory events during sleep, such as apnea and hypopnea, can impair the transmission of nerve impulses along the auditory pathway that are highly dependent on the supply of oxygen. However, this association is not well established in the literature. OBJECTIVE: To compare the evaluation of peripheral auditory pathway and brainstem among individuals with and without obstructive sleep apnea...

INTRODUCTION: Pediatric obesity is a leading risk factor for obstructive sleep apnea (OSA), a condition commonly treated with adenotonsillectomy (T&A). It has been hypothesized that obesity increases a child's risk of failing T&A for OSA, however this relationship has not yet been quantified. The primary objective of this study was to investigate the relationship between obesity as measured by perioperative Body Mass Index (BMI) and persistent OSA following T&A as measured by polysomnography (PSG)...

The diagnosis and management of obstructive sleep apnea (OSA) are increasingly being performed in the home. In the home management pathway, patients with high pretest probability for OSA are first tested using home sleep apnea testing and if positive for OSA, are treated with automatic positive airway pressure (APAP). The home management pathway has been validated by multiple investigators1-3 and is considered an alternative pathway in guidelines for the evaluation and management of OSA.4 However, there are limitations to the routine use of this pathway...

: Continuous positive airway pressure (CPAP) is the first-line treatment for moderate to severe obstructive sleep apnea syndrome (OSAS). Up to 25% of patients with OSAS discontinue CPAP treatment due to side effects. Unintentional leak and its associated annoying consequences are the most frequently reported adverse effects of CPAP. Successive technological improvements have not succeeded in addressing this issue. OBJECTIVES: A systematic review was conducted: (i) to assess the impact of different technological advances on unintentional leak and, (ii) to determine if any patient characteristics have already been identified as determinants of unintentional leak...
