Active clinical trials for "Sleep Apnea, Obstructive"

The purpose of this study is to test the hypothesis that obstructive sleep apnea syndrome is associated with deviant pharyngeal swallowing function, using clinical, endoscopical and manometric evaluation.

The goal of this research is to study the prevalence of sleep disordered breathing and associated morbidity in obese children and to examine the role of diet and physical activity in the treatment of sleep-disordered breathing in obese children.

The purpose of this study is to determine whether patients with obstructive sleep apnea have any changes in left ventricular function and structure after 06 months of continuous positive airway pressure treatment.

This study will take between 1-2 months (with first patient first visit to last patient last visit). Each participant will use the supplied PAP device and mask for a period of up to 14 nights. Participants will complete a series of questionnaires. The study will collect data to support the development of an advance leak detection technology.

Obstructive Sleep apnea carries a variety of complications and implications. While the disease could be treated using continuous positive airway pressure (CPAP) and lifestyle changes, many patients find it difficult to adjust to the mask, and turn to surgical options. The conventional surgical options to date ranges from radical (UPPP) to individualized, with or without Drug-induced sleep endoscopy (DISE). Previous studies showed that dise directed surgery can be useful for specific conditions. No trials were found to test in-office encompassing minimal invasive surgical treatment (RF palatoplasty , RF tonsillotomy, RF turbinectomy, and RF base-of-tongue reduction) as a viable alternative..

During induction of anesthesia in children, the investigators have observed significant variability in mask holding technique at our institution among different anesthesia practitioners. Some hold the face mask using one hand and others use two hands. The aim of our study is to comparatively evaluate the extent of airway obstruction in children whilst anesthetic mask is held with one hand with jaw thrust versus mask held using two hands with chin lift by anesthesia provider during induction of anesthesia in children.

Prospective study of sleep disordered breathing in a lung cancer screening cohort.

The study will begin in 2013 whereby patients having an early warning system (EWS) alert will be randomized to be seen by the rapid response team (RRT) for triage versus usual care. A RRT is usually made up of a nurse and/or a physician who respond to a requested activation of the RRT (called an "ACT"). The intervention will occur as follows:

The purpose of this study is to develop an efficient home-based polysomnography device, which allows, through GPRS,continuous real-time monitoring from the sleep lab based in the hospital, in order to decrease the failure rate of home-based recordings.
