OBJECTIVE: To validate the use of the event detection capabilities in an auto-CPAP system used by patients with sleep apnea hypopnea syndrome (SAHS). METHODS: A total of 28 subjects with SAHS were recruited in the study. All the underwent tests of polysomnography (PSG) before and during treatment by an-auto-CPAP system with advanced event detection (AED) in the sleep lab. Apnea-hypopnea index (AHI), apnea index (AI) and hypopnea index (HI) by PSG and PAP machine were compared...

STUDY OBJECTIVES: Pressure-relief features are aimed at improving the patient's comfort during continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea. The objective of this study was to determine the effect of these therapy features on fixed CPAP and autotitrating CPAP (APAP) treatment efficacy. METHODS: Seven pressure-relief features applied by three CPAP devices were included in our study (Remstar Auto: C-Flex 3, C-Flex+ 3, A-Flex 3, P-Flex; AirSense 10: EPR 3; Prisma 20A: SoftPAP 2 and 3)...

BACKGROUND: Patients under treatment with continuous positive airway pressure (CPAP) may have residual sleep apnea (RSA). OBJECTIVE: The main objective of our study was to evaluate a novel auto-CPAP for the diagnosis of RSA. METHODS: All patients referred to the sleep laboratory to undergo CPAP polysomnography were evaluated. Patients treated with oxygen or noninvasive ventilation and split-night polysomnography (PSG), PSG with artifacts, or total sleep time less than 180 min were excluded...

Obstructive sleep apnea-hypopnea is a highly prevalent disease that is often underdiagnosed at present. It has a significant economic and social welfare impact, accounting for a large part of the resources assigned to home respiratory therapies. As part of the 2014 SEPAR Year of the Chronic Patient and Domiciliary Respiratory Care sponsored by the Spanish Society of Pulmonology and Thoracic Surgery, this article reviews the most recent publications on the indications and controversial issues in the treatment of sleep apnea, the latest evidence for indication of various positive pressure devices, and adjustment modes, ranging from the use of empirical formulae or mathematical estimations to modern auto-CPAP equipment, while not forgetting the gold standard of manual titration...

SESSION TITLE: OSA PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: Drug Induced Sleep Endoscopy (DISE) is a technique used to evaluate the point of airway obstruction in patients with obstructive sleep apnea syndrome (OSAS) in order to plan corrective surgery. The standard treatment for OSAS is nasal continuous positive airway pressure (CPAP), but there are a small percentage of patients that do not respond to CPAP and maintaining high apnea-hypopnea index (AHI)...

SESSION TITLE: OSA PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: CPAP Compliance in OSAHS is low all over the world. Studies evaluating compliance related issues in Indian patients using CPAP are scarce. METHODS: 35 patients of moderate to severe OSAHS who agreed to use CPAP after full polysomnography and titration studies between Jan-June 2013 and after 12 weeks were reviewed in OPD and asked to fill a prestructured questionnaire about compliance to PAP therapy...

SESSION TITLE: OSA PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: Asses relationship between a poor clinical outcome in patients and therapeutic pressure variation determined by Auto CPAPMETHODS: Patients with poor clinical outcome after establishing fixed pressure CPAP with formula (F cpap), were placed in 3 groups according to the reasons for poor control: low tolerance, no clinical improvement and bad therapeutic adherence...

RATIONALE: In obstructive sleep apnea patients (OSA), continuous positive airway pressure (CPAP) adherence is crucial to improve symptoms and cardiometabolic outcomes. The choice of mask may influence CPAP adherence but this issue has never been addressed properly. OBJECTIVE: To evaluate the impact of nasal pillows, nasal and oronasal masks on CPAP adherence in a cohort of OSA. METHODS: Newly CPAP treated OSA participating in "Observatoire Sommeil de la Fédération de Pneumologie", a French national prospective cohort, were included between March 2009 and December 2011...

OBJECTIVE: Recent evidence suggests that women with gestational hypertension (GH) have a high rate of sleep disordered breathing (SDB), and treatment for even marginal SDB may improve blood pressure control in women with GH. We assessed whether the application SDB treatment could improve blood pressure in women with GH. METHODS: This was a single-center randomized study. Subjects underwent an unattended home-based diagnostic sleep study. The study was then repeated with subjects wearing one of two randomly assigned treatments: auto-titrating continuous positive airway pressure (auto-CPAP) or mandibular advancement device (MAD) + nasal strip...

PURPOSE: There are little existing data on continuous positive airway pressure (CPAP) adherence in US Hispanic veterans with obstructive sleep apnea (OSA). Our aim was to describe determinants of 1-month adherence in a sleep clinic cohort of South Florida Hispanic veterans. METHODS: Hispanic veterans referred to the Miami VA sleep clinic were recruited and completed questionnaires about sleep apnea risk, sleep quality, insomnia symptoms, sleepiness, depression/anxiety, acculturation, personality traits, and cognitions about OSA and CPAP...

PURPOSE: Autotitrating continuous positive airway pressure (auto-CPAP) devices not only titrate CPAP pressures but also measure residual respiratory events. The aim of the present study was to determine the accuracy of auto-CPAP-derived residual apnea-hypopnea index (AHI). METHODS: We studied 137 consecutive patients (72.3% men) with obstructive sleep apnea from January 2008 to December 2010 who underwent in-laboratory overnight polysomnography (PSG) using auto-CPAP...

PURPOSE: Auto-CPAP devices (APAP) are controlled, e.g.,by the respiratory flow and pressure to adjust the treatment pressure to the variable obstruction in sleep apnea syndromes.By obstruction of the upper airway during inspiration,a pressure difference between the lower airways and the mask can be measured. In case of an opening of the pharynx at the end of the obstruction, the pressure decreases immediately. This brief negative pressure, the so-called obstructive pressure peak (OPP) can be used to identify obstruction or open airways with the algorithm of an APAP device...

PURPOSE: This study was made to evaluate the effect of automatic continuous positive airway pressure (auto-CPAP) versus fixed continuous positive airway pressure (fixed CPAP) in reducing the apnea-hypopnea index (AHI) and the mean therapy pressure, improving subjective sleepiness, sleep architecture, patient compliance, and preference in patients with obstructive sleep apnea. METHODS: We searched the electronic databases MEDLINE, EMBASE, the Cochrane Library, and Google Scholar...

BACKGROUND: New approaches are needed to treat patients with stroke. Among acute ischemic stroke patients, our primary objectives were to describe the prevalence of sleep apnea and demonstrate the feasibility of providing auto-titrating continuous positive airway pressure (auto-CPAP). A secondary objective was to examine the effect of auto-CPAP on stroke severity. METHODS: Stroke patients randomized to the intervention group received 2 nights of auto-CPAP, but only those with evidence of sleep apnea received auto-CPAP for the remainder of the 30-day period...

BACKGROUND: Continuous positive airway pressure (CPAP) is the elective treatment of obstructive sleep apnea. The therapeutic level of CPAP is generally established by manual titration or an auto CPAP device, but an alternative way involves the use of predictive formulas. The aim of the present study was to test the difference between mathematical equations and CPAP or auto CPAP in terms of therapeutic pressure. METHODS: A retrospective analysis of 197 subjects with a diagnosis of obstructive sleep apnea needing a CPAP treatment was performed...

BACKGROUND: The high efficacy of continuous positive airway pressure (CPAP) in treating obstructive sleep apnea (OSA) is limited by poor compliance often related to pressure intolerance. Mandibular advancement devices (MADs) are proven alternative therapy although not universally effective. A combination of nasal CPAP and MAD may provide another option for CPAP-intolerant patients with incomplete response to MAD. METHODS: Ten patients with residual apnea/hypopnea events on MAD who were intolerant to CPAP were recruited prospectively from the sleep clinic...
