Active clinical trials for "Sleep Apnea, Obstructive"

Obstructive sleep apnea (OSA) can be described as a condition characterized by repetitive obstruction of the upper airway resulting in oxygen desaturation and awakening from sleep, loud snoring, and increased daytime sleepiness . Many studies have shown that a link exists between OSA and cardiovascular disease, chronic heart failure ischemia, hypertension, obesity, and impaired glucose tolerance . A number of factors are likely to play role in development of clinical OSA syndrome (OSAS) ranging from upper airway anatomy to central respiratory control mechanisms. The pathophysiology of OSA is unclear and complex. Several previous studies have explored pulmonary function in the OSAS patients Interestingly, OSAS has been found to be highly correlated with lower airway obstruction, although it is originally defined as an upper airway disease

The purpose of this study is to find the correlation between high risk OSA (obstructive sleep apnea) patient, based on Stop-bang screening tool and preeclampsia

In children with OSA (Obstructive sleep apnea) adenotonsillectomy is regarded as the first choice of treatment. Studies in recent years have shown that the procedure does not always have the expected effect. Children with OSA are at greater risk for complications from the procedure. There is disagreement regarding the need for sleep studies in children prior to surgery in order to verify an OSA diagnosis. Today less than 10% of these children have polysomnography (PSG). The main purpose of this study is to describe the prevalence of OSA among children referred for adenotonsillectomy. The investigators will also examine these children prior to and six months after surgery to assess their sleep pattern and quality of life. The project outcome aims to improve the precision and quality of diagnosis and the short and long term effects of treatment of children with OSA.

This study explore AAA prevalence in OSAHS patients by ultrasound screening and try to analysis risk factors of AAA in OSAHS patients.

The primary study objective is to investigate sensitivity and specificity of a wrist sensor pulse oximeter (the Oxitone Medical Oxitone 1000M device) to screen for obstructive sleep apnoea. This study will involve thirty participants attending a sleep centre suspected of suffering from obstructive sleep apnoea (case finding screening). The secondary objective is to assess patient convenience with the screening procedure.

assess the relationship between obstructive sleep apnea and endocrine, inflammatory, and metabolic bio-markers in consecutively enrolled adult male patients with a clinical suspicion of obstructive sleep apnea.

A Prospective, Observational, Post-market Surveillance Study to Evaluate the Long-term Safety and Efficacy of the iNAP® Lite Sleep Therapy System in Adults with Obstructive Sleep Apnea

A total of 400 participants will be recruited: 200 patients with suspected OSAS will be recruited from the sleep clinic (OSAS group), 100 patients diagnosed with dizziness will be recruited from the ENT clinic (Dizziness group). In addition, 100 patients with no dizziness and no evidence for OSAS will be recruited from both the sleep clinic and the ENT clinic (controls). Informed consents will be completed by all participants. ). In order to assess the effect of treatment of OSAS on dizziness -patients with the diagnosis of OSAS will complete validated questionnaires regarding sleep, dizziness and eustachian tube function 3 months following initiation of treatment with CPAP

The aim of this study is to validate the downloadable mobile snore applications by polysomnography.

Covid-19 infection is an on-going pandemic with worse diagnosis in adults with comorbid conditions such as hypertension and cardiopulmonary diseases. Obstructive sleep apnea (OSA) is common in those comorbidities and may contribute to worse prognosis for the Covid-19 cases.
