Active clinical trials for "Sleep Apnea, Obstructive"

Non-alcoholic fatty liver disease is associated with obstructive sleep apnea. Abnormalities in liver enzymes can improve following continuous positive airway pressure in patients with obstructive sleep apnea. Computerized tomography can be used to quantify fatty liver changes. We hypothesize that continuous positive airway pressure can reduce morphologic fatty liver changes in patients with obstructive sleep apnea and non-alcoholic fatty liver, an that this reduction can be evident using computerized tomography

This study seeks to understand the physical, physiologic and biologic features that predispose a woman to the development of obstructive sleep apnea once they are exposed to the cardiopulmonary and metabolic physiological changes of pregnancy. Knowing these specific predictive factors can help identify a population at risk and guide clinicians to develop suitable targeting screening strategies.

Prospective, non-randomized, open label study

Inspire intends to conduct this study to compare Apnea-Hypopnea Index (AHI), between the two randomization arms, at 6 months post-activation

All patients are newly diagnosed Obstructive Sleep Apnea patients performing full night polysmnographic sleep study, whose echocardiographic findings elucidate presence of pulmonary hypertension(PH). These patients seemed to have PH if mPAP ≥25 mmHg . All studied patients were received CPAP therapy with average cumulative adherence ⩾4 h/day of >70% nights [380] obtained from device download with AHI<5 /hr Echocardiography: It was performed initially to diagnose pulmonary hypertension and repeated after three months of CPAP therapy as a follow up . All enrolled patients were subjected to trans-thoracic echocardiography using Ultrasound system (Vivid I, GE Healthcare, Little Chalfont, UK), with a 2.5 MHz transducer. Certain measurements were then used to calculate mPAP. Patients were considered to have PH if mPAP ≥25 mmHg, and were classified into mild (20-40 mmHg), moderate (41-55 mmHg), and severe (>55 mmHg) degrees. Evidence of PH is found by Doppler echocardiography showing an elevated right ventricular systolic pressure (RVSP).

Prospective open-label, non-randomized, monocentric, cohort study, to assess the prevalence and severity of sleep apnea syndrome in patients treated for cancer of the upper aerodigestive tract. The patient follows a usual course of care including, at the end of the treatment of his cancer of the upper aerodigestive tract, screening for obstructive sleep apnea syndrome at 3 months and 6 months (Epworth score and ventilatory polygraphy)

This is a phase 2 randomized double-blind placebo-controlled parallel-arm dose finding study to compare fixed dose combinations of AD109 and AD504 to atomoxetine or placebo in Obstructive Sleep Apnea.

Little is understood about how different auto-adjusting PAP devices operate. The purpose of this evaluation is to compare two devices in a randomised two night PSG trial.

The purpose of the study is to observe the Pilairo mask in a lab setting.

This study will evaluate a newly developed pediatric mask (known as Pixi) on children aged 2-7 using continuous positive airway pressure (CPAP), or Non-invasive ventilation (NIV) treatment. The participants will undergo a monitored sleep study, followed by a 7 night trial of the Pixi mask in the home environment. During the study usability will be measured through questionnaires filled in by the parent and clinician. The study hypothesis is that the usability of the mask will be superior to the patient's usual mask.
