Active clinical trials for "Sleep Apnea Syndromes"

This study evaluates the correlation of the position of the head during sleep, independent of the position of the torso, and the severity of apnea hypopneas in obstructive sleep apnea.

To identify the perceptions, beliefs, and family-relevant outcomes regarding the treatment of obstructive sleep apnea syndrome (OSAS) with positive airway pressure (PAP) in children with Down's Syndrome (DS).

The main objective of this study is to provide an adequately powered study that would provide evidence on the non-inferiority of ANNE to a Home Sleep Test (HST).

This pilot study is intended to evaluate the acceptance and performance of the DreamMapper application and the Therapist Assist educational tool in naïve patients with Obstructive Sleep Apnea who have been prescribed Positive Airway Pressure therapy. A total of approximately 60 naïve participants will be recruited.

The purpose of this trial is to investigate the mechanisms leading to weight gain during CPAP treatment for obstructive sleep apnea (OSA).

In obstructive sleep apnea, the upper airway recurrently closes during sleep. The mechanisms that lead to airway closure are not completely understood. While the airway of some people narrows and airflow decreases during inspiration due to increasing inspiratory effort, others maintain constant airflow throughout inspiration. Airway neuromuscular reflexes may protect against airway narrowing that occurs due to increasing inspiratory effort. To test this hypothesis, the investigators will initially measure airway neuromuscular reflex and inspiratory flow and then attenuate neuromuscular reflex through topical pharyngeal anesthesia to observe the effects on inspiratory flow.

The investigators will perform a 1-year clinical trial measuring objective compliance during mandibular advancement device (MAD) treatment. The investigators will enroll 50 patients that received treatment with a titratable, duobloc MAD (RespiDent Butterfly®, RespiDent, Nijlen, Belgium) and participated in the original study "Objective versus subjective compliance with oral appliance therapy for obstructive sleep apnea hypopnea syndrome", registered at Clinical Trials.gov (NCT01284881). Active microsensors (TheraMon®,Handelsagentur Gschladt, Hargelsberg, Austria) are provided by the Handelsagentur Gschladt without any costs. The sampling interval of the recording will be done at a rate of 1 measurement per 15 minutes (every 900 seconds). Using this sample interval, the capacity of the active microsensor allows for data acquisition during a 100 day period. A follow-up appointment is scheduled +/- 265 days after the start of the original study. A second follow-up visit is scheduled again 1 year after the start of the original study. The objective measurement of MAD wear time (total hours of wear time and the mean hours of wear per night over the respective period) will be based on the assumption that the MAD has been worn when the chip records a temperature intraorally.

Continuous Positive Airway Pressure (CPAP) is the standard treatment in patients with Obstructive Sleep Apnea Syndrome (OSAS). The goal of the study is to evaluate CPAP treatment duration recorded by the AL539 during attended in-hospital polysomnography in patients with Obstructive Sleep Apnea Syndrome.

The purpose of this study is to assess the effects of physical exercise, associated or not with venous compression of the leg, on obstructive sleep apnea (OSA) severity and upper airway resistance in obese teenagers. Half of the participants will undergo physical exercise and compression socks program, and the other half of subjects will undergo physical exercise program without compression socks.

The purpose of this pilot study is to determine the feasibility of using a novel treatment for sleep apnea in which the patient's own exhaled CO2 is tightly controlled and used in a rebreathe system to reduce sleep disordered breathing.
