Active clinical trials for "Sleep Apnea, Obstructive"

This study looks at the quality of the common mechanisms used to diagnose obstructive sleep apnoea (OSA) by patients in their own homes. These are pulse oximetry as a stand alone measurement and multi-channel respiratory studies that measure oximetry but also record some combination of signals including airflow at the mouth and or nose, chest and abdominal expansion, body position and snoring. This study will examine the patient acceptability of these methods and the proportion of studies that achieve various levels of technical quality ranging from a full night with all data available to a completely failed study and categories in between.

The purpose of this study is to test a pediatric narcolepsy patient reported outcomes tool to assess pediatric narcolepsy symptoms and their effect on daily functioning and quality of life. The goal is to develop a clinical survey that can improve the care of pediatric narcolepsy.

Obstructive sleep apnoea is a highly burdensome condition that not only impairs function but also confers a risk of cardiovascular disease. This is particularly evident among those who are poorly compliant with continuous positive airway pressure ventilation therapy. In the management of a chronic and frequent pathology such as OSA, it is necessary to have personalized programs that implement new technology-based tools to improve the comprehensive management of the patient in order to reduce the morbidity associated with this disease.

The purpose of this clinical investigation is to evaluate the performance and safety of the F&P Caramel nasal mask in a home environment.

The goal of this clinical trial in adults with obstructive sleep apnea prescribed positive airway pressure therapy is to test the effects of a new patient-facing consumer wearable-based program (that involves provision of a consumer wearable that measures oxygen levels during sleep plus customized weekly reports to participants). The main question is to learn whether participants' use of positive airway pressure therapy will differ between the participants who receive the new program immediately versus delayed. Participants assigned to the delayed program will receive usual care while waiting for the program to begin.

Each Whitsunday mask or AirFit N30i Quiet mask is worn for 7 nights. The overall purpose of this study is to evaluate the performance of the Whitsundays nasal mask system (a prototype mask) compared to the ResMed AirFit N30i Quiet mask system (a benchmark mask) in relation to seal, comfort, usability, overall performance, and efficacy.

This study will examine factors associated with outcomes after soft palate surgery and medications (acetazolamide, eszopiclone) that may treat other potential causes of obstructive sleep apnea (loop gain, arousal threshold).

Sleep disorders are commonly under-recognized in the primary care setting and available screening tools are often are limited. The study inestigators hypothesize that the use of a novel subjective sleep vital sign (VS) will improve recognition of patients with sleep disorders and can be utilized to track outcomes to sleep therapy.

Obstructive sleep apnea syndrome (OSA) is thought to lead to systemic vascular lesions that may be preceded by early microvascular lesions in the eyes and in particular in the retina. The improvement of ophthalmological imaging techniques by OCTangiography allows a precise non-invasive study of the retinal microvascular network. This new rapid and non-invasive retinal imaging tool could reveal micro-vascular lesions related to OSA. To the investigator's knowledge, this would be the first OCT-angiography description of a cohort of patients with OSA. If these results are confirmed, it would be interesting to study the correlation between these micro-vascular lesions and the cardiovascular risk of his patients.

Obstructive sleep apnea (OSA) is a common condition associated with significant adverse health outcomes. Our overarching hypothesis is that patients with OSA and hypoxia (H-OSA) have greater degrees of insulin resistance in both liver and adipose tissue when compared to those without hypoxia (NH-OSA) thus leading to increased risk for the development of diabetes in the former group.
