Active clinical trials for "Sleep Apnea, Obstructive"

The 4 following scores have been proposed to detect OSA (Obstructive Sleep Apnea): DES-OSA, STOP-Bang, P-SAP, and OSA50. The aim of this study is to evaluate the optimal cutoff value of these four scores to detect specifically serve OSA patients with hypoxemia.

This is an exploratory study designed to evaluate the incidence of, and to quantify sleep disordered breathing following stage I Norwood reconstructive surgery. Sleep disordered breathing will be correlated with: Elevations in pulmonary vasculature resistance at the time of Stage II surgery. Risks of death

Sleep is a fundamental need for human and is associated with the working performance and the disease occurrence. Furthermore, the amount of people with sleep disorder or apnea increased largely. Thus, the analysis of sleep stages and the measurement of sleep quality became more important recently. In clinical settings, the analysis of daily sleep quality depends on actigraphy and sleep log. However, the uses of actigraphy and sleep log are not really convenient for patients. In this trial, the investigators will measure the subjects' ECG signal and movement using a portable ECG device with motion sensor. On the other hand, the sleep stages are also obtained from the current wide-established measurement- polysomnography. The ECG signals, movements, and sleep stages will be analyzed by our algorithm of artificial neural network. Then, the investigators can obtain the preliminary analysis of sleep quality can be obtained by using ECG device with our algorithm. It is helpful for doctors to realize the patent's sleep quality quickly

This study aims to determine the prevalence and prognosis of heart failure with preserved ejection function (HFpEF) among patients being assessed for sleep disordered breathing (SDB).

Patients with type 1 diabetes have poorer glycemic control that could lead to macrovascular or neuropathic complications; in addition to an optimal treatment, prevention of diabetes complications requires to control associated risk factors, such as hypertension or dyslipidemia. Sleep apnea syndrome is a public health problem due to its high prevalence and marked morbidity and mortality, one increasingly interesting aspect is its relationship with metabolic disorders, specifically diabetes.Obstructive sleep apnea syndrome seems to be underestimated in this population. In this context, it appears to be important to estimate the prevalence of sleep respiratory diseases in patients with type 1 diabetes.

Sleep disorders and disturbances are mostly underestimated in clinical practice. Moreover, this problem is generally neglected by the pregnant themselves. Today, it is important to underline any problem that may have an affect to improve the quality of life during pregnancy. This study assesses the sleep quality, insomnia patterns and obstructive sleep apnea in the second and third trimesters of pregnancy.

Presently, there isn't any international recommendation to evaluate vigilance in Obstructive Sleep Apnea Syndrome. The French Society of Sleep Research and Medicine (SFRMS) recommend evaluating professional driver with a MWT but no recommendation exists for other patients. After a minimal treatment of 4 weeks, the physician has to evaluate the drowsiness risk of these patients using either an objective test like the MWT or a subjective one. In the university hospital Amiens-Picardie, since the 01/01/2015, every patient with an Obstructive Sleep Apnea Syndrome diagnosed by a polysomnography or a ventilatory polygraphy had a MWT after 4 weeks of treatment. At each time of the evaluation, Epworth Sleepiness Scale, tiredness score of Pichot, and depressive score of Beck are performed.

Prospective study designed to identify factors that would predict patient adherence to CPAP (Continuous Positive Airway Pressure) therapy.

Recent clinical findings of research at Trondheim University Hospital suggest that surgical correction of the nose septum in addition to volume reduction of the nose cavity may be beneficial in patients who suffer from both nose obstruction and obstructive sleep apnea syndrome(data not yet published). This study aims to compare nose obstruction prevalence in sleep apnea patients and the general population

The study is designed to compare the apnea event recognition capability of the Capnostream 20 with investigational software to polysomnograph recordings scored by a trained analyst. The study will compare the apnea index score (AI) calculated by the Capnostream 20 algorithm based on capnography to that calculated by a trained analyst evaluating polysomnograph recordings. To this aim, subjects will be connected to EMBLA N7000 Polysomnograph, and to the Capnostream 20, in order to monitor CO2 and SpO2 during routine overnight sleep studies. The Capnostream, using both its USB Data Port and Analog output port will simultaneously provide the monitored data both to a USB flash memory device and Polysomnograph for storage for future analysis. The data collected by the Polysomnograph including the Capnostream data will be analyzed by a trained expert for evaluation of apnea events obtained from both sources. In parallel, the Capnostream data as collected with the USB flash memory, will be downloaded onto a PC, and using the Oridion software algorithm designed for evaluating the data (to be implemented in the monitor when validated), the Apnea Index and Oxygen Desaturation Index will be calculated. The results of the Apnea Index scores calculated from the Polysomnograph and from the DUT will be compared. Based on the results, the study will then evaluate the ability of the Capnograph/Pulse-Oximeter as a tool for screening and assisting in the diagnosis of patients with obstructive sleep-apnea in the hospital environment, where it is being used as a ventilation monitor based on the demonstration of a high correlation with the gold standard in the sleep lab.
