Filter by:The investigators will conduct this study to validate Belun Ring for sleep assessment. The investigators will compare Belun Ring data collection and overnight in-lab polysomnography (PSG) measures of SDB and sleep architecture in adults with OSA symptoms. The investigators propose to recruit a total of 40 participants with symptoms of obstructive sleep apnea. The investigators will i) validate the overall accuracy, sensitivity and specificity of Belun Ring to assess SDB and sleep architecture, using PSG analysis as a gold standard.
Obstructive Sleep Apnea (OSA) syndrome is a disorder characterized by repetitive episodes of upper airway obstruction that occur during sleep. The standard treatment for apnea remains a device consisting of a pump and nasal mask that provide continuous positive airway pressure (CPAP). The major disadvantage of CPAP is the relatively low compliance. Appscent developed a non-contact effortless bedside solution based on the following: odors modify respiratory patterns during wake . Mildly trigeminal and pure olfactory odorants do not arouse or wake.
The primary medical therapies for patients with Obstructive Sleep Apnea syndrome (OSA) require the use of medical devices on a nightly basis to help control breathing during sleep, which can be difficult for patients with mild-to-moderate disease. Because many patients use these therapies on a limited basis, or stop using them altogether, they continue to be at increased risk of the consequences of untreated OSA. Untreated and undertreated OSA compounds the risk of OSA consequences over time, particularly with increasing age and weight. Orofacial Myofunctional Therapy (OMT) takes a rehabilitative approach to OSA and is comprised of isotonic and isometric exercises that target the oral (e.g., tongue) and oropharyngeal (e.g., soft palate, lateral pharyngeal wall) to help restore normal breathing and airway patency at night while asleep. Should the study have positive findings, OMT could become an important alternative therapy for patients with mild-to-moderate disease because patients could utilize a therapy that improves their nighttime breathing through daytime exercises and without the need for a burdensome medical device.
Obstructive sleep apnea (OSA) is a common sleep disturbance that can cause intermittent hypoxia, hypercapnia, and sleep structure disorders. The presence of OSA is associated with worse outcomes after surgery including increased incidence of complications. High-flow nasal cannula (HFNC) therapy can improve oxygenation of OSA patients by maintaining a certain positive pressure in the nasopharyngeal cavity. Previous studies showed that, dexmedetomidine supplemented analgesia can improve sleep quality and pain relief. The investigators hypothesize that, for high-risk OSA patients following major non-cardiac surgery with HFNC therapy, dexmedetomidine supplemented analgesia can improve sleep quality. The purpose of this pilot randomized controlled trial is to investigate the impact of dexmedetomidine supplemented analgesia on sleep quality in high-risk OSA patients after major non-cardiac surgery.
The aim of this study is to evaluate in a clinical trial a rehabilitation device for patients with obstructive sleep apnoea (OSA) based on oropharyngeal electrical stimulation, which strengthens the dilating muscles of the upper airway, improves mechanical laryngopharyngeal sensitivity and improves OSA. Furthermore, to perform experimental electrotherapy, nasoendoscopy, polygraphy and polysomnography tests with the device in order to calculate thresholds of functional and sensory intensities on the dilating muscles of the upper airway in patients with OSA. These tests also include the detection of signals that measure breathing events during sleep in patients with OSA in order to use them in the control mechanisms of the electrostimulation device. Assess the effects and safety of the device in a group of five healthy volunteers for preliminary results. Finally, to evaluate in a small group of patients with OSA the device capacity to stimulate the upper-airway dilating muscles and to reduce the Apnea-Hypopnea Index (AHI) and oxygen desaturation indices when the electrostimulation device is used over a medium-term period (eight weeks) with morning and evening therapy sessions.
Rapid maxillary expansion (RME) is a commonly used orthodontic treatment in patients with maxillary constriction to provide skeletal expansion, correct posterior crossbite and resolve naso-respiratory problems by reducing oral respiration.The aim of this randomized controlled trial was to evaluate the effects of tooth-borne, tooth tissue-borne and bone-borne RME appliances on sleep quality with polygraphy. The null hypothesis was that there is no difference for the sleep quality between the appliances.
This study will evaluate the influence of sleep apnea on clinical and radiological features of MS. Sleep apnea is associated with hypoxemia during sleep, which is likely detrimental to MS. Clinical data (MRI, lab results, medical history, labs, and sleep studies) of MS patients will be collected and analyzed. This will be done to study correlations between MRI, clinical data, lab studies and sleep studies. There is specific interest in the type of sleep apnea associated with MS, and whether MRI or clinical metrics of MS severity correlate with presence or absence of sleep apnea.
This is a single group, unblinded, prospective clinical study. This study seeks to understand patient diagnostic and treatment journey and positive airway pressure (PAP) therapy compliance for Verily Sleep Apnea (VSA) program/app users. Participants will enroll remotely and may undergo a home sleep test (HST). Upon confirmation of obstructive sleep apnea (OSA) and prescription of PAP therapy, the participant will begin using the VSA app to supplement PAP treatment. After 90 days of active participation, the participant will be given instructions for follow-up care, as indicated.
This is a prospective, unblinded, open-label, single group study. All subjects will undergo concurrent screener app, HSAT testing, and in-lab polysomnography.
Home sleep studies - which allow the measurement of breathing while the person sleeps - will be performed on patients with fibrotic interstitial lung disease attending two of the UK's largest respiratory medicine services.The study will investigate at how symptoms, and breathing and exercise tests differ between these two groups after 12 months of study.
