Filter by:Chronic obstructive pulmonary disease (COPD) is a chronic lung disease affecting an estimated 1 in 10 Canadians. Symptoms include persistent shortness of breath, cough and sputum production. The symptoms can be serious when people with COPD experience a flare of their disease and may lead to hospitalization or death. Improving other conditions that affect COPD control is one way to improve the health of people with COPD. Obstructive sleep apnea (OSA) is the most common breathing problem during sleep, and commonly co-exists with COPD. Although diagnosing and treating OSA is encouraged, it has not been highlighted in guidelines that recommend ideal COPD care. People with COPD and OSA have lower sleep quality and lower oxygen levels during sleep compared to people with OSA. Despite these differences, treatment of OSA in people with COPD is modeled after treatment of OSA in the general population, generally using treatment with continuous positive airway pressure (CPAP) with the possible addition of oxygen through the CPAP machine. There are few studies looking at other types of treatment including noninvasive ventilation (NIV) in people with COPD and OSA. The majority of studies of NIV in COPD has been for people with other reasons to use NIV including acute respiratory failure or chronic hypercarbic respiratory failure and did not include people with risk factors for OSA or who had undergone overnight sleep studies. In Alberta, NIV is provided province wide for people who have both OSA who do not meet certain physiologic targets in their oxygen levels or breathing patterns after CPAP is applied on an overnight sleep study. NIV is provided preferentially to CPAP and oxygen, providing an opportunity to look at health outcomes when NIV is used instead of CPAP for the treatment of patients with COPD. Through this study, we will measure whether people with COPD and a sleep related breathing disorder such as OSA have fewer severe flares of COPD after starting CPAP or NIV. We will evaluate whether the number of Emergency Department visits, hospitalizations or deaths lowers after starting CPAP or NIV.
This study is a prospective, multi-center, single-arm, open-label study evaluating the safety and effectiveness of therapy with the ProSomnus EVO Sleep and Snore Device in individuals with severe obstructive sleep apnea.
The StimAire Model S is intended to treat Obstructive Sleep Apnea (OSA) by stimulating the hypoglossal nerve. The system includes a dedicated neurostimulator and a breathing sensor. The system is to be used in participants diagnosed with moderate to severe Obstructive Sleep Apnea. The Sponsor will be evaluating the change in Apnea-Hypopnea Index (AHI) when using the StimAire Model S system.
This study aims to guide participants in recognizing their OSA (obstructive sleep apnea) and AFib (atrial fibrillation) symptoms, realizing what medical conditions can cause these symptoms (if any) and inform the participants on their possible diagnosis
Comparison of the NightBalance Sleep Position Trainer (SPT) to Positive Airway Pressure (PAP) for the Treatment of Positional Obstructive Sleep Apnea (POSA). Primary Objective: Efficacy and Adherence of the SPT over 3 months of use compared to PAP for the treatment of POSA. The study is run from centers in France, the UK and Germany.
This study aims to evaluate the association between obstructive sleep apnea (OSA) and fetal growth restriction (FGR) and to assess the role of auto-titrated positive airway pressure (aPAP) as antenatal therapy in these patients. Pregnant patients with diagnosed FGR will be screened for OSA first by screening questionnaire and then by home sleep monitor. Of those patients diagnosed with OSA, half will be assigned to use aPAP each night when sleeping and half will not (standard care).
The objective of this study is to examine the contribution of intravenous (IV) fluid administration and rostral fluid shift from the legs to the neck thereby leading to worsening of sleep apnea following surgery. In this prospective, observational cohort study, 50 consecutive preoperative adult obstructive sleep apnea (OSA) patients, requiring at least one night hospital stay post surgery, will be recruited. Recent research from general population suggests that intravenous (IV) fluid administration worsens the severity of OSA by shifting of fluid from the legs to the neck thus increasing neck size and causing airway collapse. The results of this study will be used to design future clinical trials evaluating methods to decrease postoperative OSA worsening, as well as decreasing OSA-related postoperative complications.
Obstructive sleep apnea (OSA) has been found to be very common in stroke patients. Obstructive sleep apnea has been found to impede stroke rehabilitation and recovery. However, currently, there are few treatment options for OSA in stroke patients. Continuous positive airway pressure (CPAP) is the current therapy commonly used for OSA in the general population, however stroke patients are not highly compliant with this device. Therefore, we have decided to propose a more feasible alternative to treating obstructive sleep apnea through positional therapy. Positional therapy involves using a device to prevent patients from sleeping on their backs, since this position has been found to exacerbate obstructive sleep apnea. Therefore, we hypothesize that stroke patients who use the positional therapy belt will experience improvements in the severity of OSA.
The investigators have previously shown that 1 week of 10mg Melatonin improves sleep consolidation in untreated obstructive sleep apnea (OSA) patients. This study aims to extend on those findings to determine if longer treatment of Melatonin improves other outcomes in untreated OSA patients.
Earlier studies suggest that acoustical analysis of snoring sounds can identify obstructive sleep apnea (OSA). The goal of the current study is to refine and validate algorithms for OSA diagnosis.
