Filter by:Assessment of the association of maxillary expansion using a rapid palatal expansion, use of a mandibular advancement appliance (MGA™) and of a device allowing sleep in a semi-seated position (Yoobreath™) in patients with Obstructive Sleep Apnea (OAS). MGA™ and YooBreath™ constitute the Yookid system™.
Correlation of severity of obstructive sleep apnea and function of the right ventricle by means of 2D echocardiography and cardiac MRI
Obstructive sleep apnea (OSA) is an extremely common disease with inadequately explored neurocognitive consequences. The investigators will study OSA patients before and after treatment to understand how OSA changes decision making abilities, and whether treatment can reverse such cognitive changes. These results could provide deeper insight into how OSA affects decision making either temporarily or permanently, and provide another rationale or motivation for treatment of OSA in adults.
This study evaluates the utility and reliability of Somnocheck micro Weinmann for obstructive sleep apnea syndrome (OSAS) screening in patients affected by resistant systemic arterial hypertension. Results are compared with a modified portable sleep apnea testing (type III portable monitoring: Somnocheck 2 Weinmann).
A prospective double blind, placebo-controlled, randomized cross-over trial to evaluate the effect of lowering cerebral blood flow on the ventilatory chemoreflexes (acute hypoxic and hypercapnic ventilatory responses).
A study undertaken to investigate mouth leak for airway discomfort/dryness while using CPAP. This study will also measure how much humidification is required to treat subsequent upper airway discomfort/dryness from mouth leak by utilizing different levels and types of humidification.
Background Maxillomandibular advancement surgery (MMA) has demonstrated high success rates, improving both the apnea-hypopnea index and associated patient' quality of life (QOL), in patients diagnosed with obstructive sleep apnea syndrome (OSAS). However, clinical relapse has been described in the target population, especially when associated with significant weight gain. Literature reporting the long-term impact of MMA for OSAS is lacking. The surgeons of the Division of Maxillofacial Surgery already started to perform this type of surgery in 1995. Objectives The investigators aim to evaluate the long-term (minimum 15 years post-surgery) biologic and QOL impact of MMA in patients with OSAS. The biologic impact refers to the stability of hard and soft tissues and polysomnographic results. Study design Retrospective study Both pre- en postoperative clinical imaging, polysomnography and quality of life questionnaires will be retrieved from all patients that were surgically treated with an MMA by one surgeon (CDC) between 01/11/1995 and 01/12/1999. Conclusion Short-term data have shown high success rates for MMA in OSAS patients. However, long-term data are lacking. This retrospective study might provide us with more information about the incidence of clinical relapse fifteen to twenty years after surgery.
The study is a prospective, randomized, controlled trial studying adherence to positive airway pressure therapy in a population referred to the VA system for the treatment of sleep disordered breathing. The primary aim of the study is to determine if, compared to standard care provided at a VA Sleep Center, the deployment of a structured adherence management program and a web-based information program designed for participants beginning positive airway pressure therapy results in a greater portion of participants meeting Centers for Medicare & Medicaid Services (CMS) adherence requirements (use > 4 hours for >= 70% of days) at 90 days.
With this pilot study, we are hoping to test the feasibility of a larger study in the future and to learn whether positive airway pressure therapy reduces the recurrence risk of atrial fibrillation after successful catheter ablation procedure among patients with atrial fibrillation and obstructive sleep apnea. The results from this study will help us refine the design for a future larger study, and will ultimately improve care of patients with obstructive sleep apnea and atrial fibrillation.
This investigation is a prospective, non-randomized, non-blinded study. This investigation is designed to evaluate the performance, comfort and ease of use of the F&P Toffee nasal pillows mask amongst obstructive sleep apnea (OSA) patients. Up to 45 OSA patients will be recruited from the Ohio Sleep Medical Institute (OSMI)
