Active clinical trials for "Sleep Apnea Syndromes"

This study is designed to evaluate the amount of heart rate variability (HRV) for women with gestational diabetes mellitus (GDM) and to determine whether women with GDM have transient sleep-disordered breathing (SDB) during pregnancy.

The primary objective of the study is to gather data to correlate physiological signals measured by the AVIVO™ Mobile Patient Management System with the patient's respiratory status, including apnea and hypopnea events, during polysomnography

The purpose of this study is to determine whether patients with obstructive sleep apnea have any changes in left atrial morphology and function evaluated by echocardiography three dimensional

The primary endpoints for this study are that the AL validation will 1) achieve a sensitivity of greater than 80% for AHI values greater than or equal to 15, and 2) demonstrate a correlation coefficient of r=0.75 indicating strong correlation between the AHI of diagnostic PSG and AL.

To investigate the prevalence and clinical significance of sleep-disordered breathing (SDB) in children.

To collect fundamental data regarding the distribution of measures of sleep disordered breathing (SDB) in a pediatric population, prevalence of clinically significant SDB in children, risk factors, and associated co-morbidity.

To undertake normative data collection of existing clinical algorithms using existing oximetry technology.

The anatomical changes of the upper airway in a standing vs pseudo-supine position using Carestream Orthodontic Imaging (Volumetric) and Carestream Orthodontic Imaging module (AP measurements) of the patient's airway respectively, have been taken and the obtained results compared. In order to simulate the supine position, patients are placed in a supine position (180 degrees) in a dental exam chair, and asked to relax their lower jaw, allowing it to drop back, simulating their jaw falling back while sleeping. That bite is then captured with a Correct Plus™ Impression Material Superfast. Once the bite material hardens, it locks the bite in place. The patient then stands upright, and CBCT is taken standing while the jaw placement is still pseudo sleep-supine, supported by the bite material.

In this study the feasibility of detecting sleep apnoeas with unobtrusive wearable sensors and sounds recorded with a smartphone is studied by making an overnight recording to patients with high probability of sleep apnoeas. The data acquired with the aforementioned devices is: ECG, acceleration, bioimpedance of thorax and processed and raw audio. In data analysis phase it will be studied which combinations of these signals would enable detecting sleep apnoeas with high enough sensitivity and specificity when compared to a night polygraphy reference (Nox T3 device using airflow, breathing movements, audio, position, movement, oxygen saturation, pulse and leg EMG).

Our study aims to determine the frequency of individuals at high risk of obstructive sleep apnea, and excessive daytime sleepiness, as well as any potential association between these conditions and traffic accidents among a sample of Ecuadorian bus drivers.
