Filter by:This study will evaluate the effect of hypoglossal nerve stimulation (HGNS) on different measures of cardiovascular function in patients with obstructive sleep apnea (OSA). People with OSA who have undergone implantation of the hypoglossal nerve stimulator at the study site will be told about the study at their 2-week post-operative appointment. Those who decide to participate will have blood drawn and vascular function measurements taken before HGNS activation, during treatment, and after a temporary treatment withdrawal period. Following the 30-day period of treatment withdrawal, the HGNS therapy will be reactivated.
Obstructive sleep apnea (OSA) is the most common type of sleep apnea. The marketplace currently does not have an affordable, easy-to-use, over-the-counter, home-based OSA screening device. An affordable, available, FDA-approved and easy-to-use over-the-counter OSA screening tool would allow greater screening of at-risk individuals, especially in underserved communities with low socioeconomic status, hopefully encouraging a greater proportion of such individuals to seek treatment for their condition. Over the past year, this investigative team has engineered a small screening device (Zerify®) for OSA and obtained preliminary evidence of its efficacy in a clinical population under a NIMHD-sponsored Phase I STTR award. Phase I Specific Aims 1 and 2 focused on developing a small (1.5 x 2.5 x 0.2 inches) semiconductor sensor that could store sound/motion data, transfer these data to a computer, and detect non-clinical simulated apnea events with a specificity and specificity exceeding 90%. Phase I Specific Aim 3 established the preliminary psychometric performance data of the screening device in a clinical sample of 52 patients (13% African American, 6% Asian, 4% Mixed or Other Race) against gold-standard polysomnography. Phase II proposal aims to optimize the engineered hardware and associated OSA algorithms, create a patient companion app and wireless healthcare provider dashboard, and compare the efficacy of this screening device to the most commonly utilized sleep apnea screener, the home sleep apnea test (HSAT).
This study will investigate the efficacy of the FPH modified positive airway pressure (PAP) device with or without SensAwake; and with different pressure support in OSA participants; in both an in-home and in-lab environment. Comfort, compliance and the accuracy of the pressure delivery will also be evaluated. The FPH device will be compared to a market released product.
Prospective observational study of obstructive Sleep Apnea patients treated with Bilevel Positive Airway Pressure: AirCurve 10 VAutoTM
This study evaluates whether objective compliance monitoring can increase mandibular advancement device (MAD) usage in obstructive sleep apnea (OSA) patients. Half of participants will be assigned to objective compliance monitoring group (experimental group), while the other will be assigned to subjective compliance monitoring group (control group). A physician will prescribe and explain to patients based on data from objective or subjective compliance monitoring.
Obstructive sleep apnea is a condition that affects 40% to 62% of the population aged over 60 years with major consequences especially on the cardiovascular system. This syndrome consists of a staff of the pharyngeal muscles. These muscles are also involved in swallowing phenomena and chews, or many elderly patients are subjected to a mixed diet, logically leading to atrophy of the muscles aerodigestive crossroads. Muscle wasting ENT induced a mixed food could promote collapsibility of VAS, exposing the individual to a higher risk of apnea and hypopnea during sleep. The objective of this study is to determine if there is a significant increase in the prevalence of obstructive sleep apnea syndrome in the elderly patients residing in long term care units, receiving a mixed food compared to residents in supply to normal texture.
Subjects will all have a two week baseline period in which they will use a nasal mask using an air view CPAP machine (which records all data). After the two week period all will switch to a full face mask with half using the same CPAP pressure and half with a new a CPAP pressure derived from our formula for the final two weeks.
Monocentric comparative group study comparing the efficacy and short-term tolerance of a propulsion type oral appliance (Herbst) with a retention type device (ORM) used in the treatment of sleep apnea syndrome. The investigators hypothesized both appliances would be equally effective and tolerated.
This investigation is designed to evaluate the performance, comfort and ease of use of the Simplus and Eson masks amongst NIV patients who are currently on Bi-level therapy
Obstructive sleep apnea (OSA) is highly prevalent among Veterans, and is associated with significant mortality and multiple morbidities. Available treatments have had limited effectiveness in treating OSA and alleviating associated morbidity. The investigators' previous research found a reduction in OSA severity of approximately 25% following modest exercise training. That this effect occurred independent of weight loss raises the exciting possibility that exercise combined with weight loss could reduce OSA by at least 50% and have unique health benefits for OSA patients. Following screening and baseline assessments, 90 overweight Veterans ages 18-60 years with OSA will be randomized to one of three 16-week treatments: (1) exercise training; (2) 10 % weight loss; and 3) exercise + weight loss. Changes in OSA and related morbidity will be compared between treatments.
