Filter by:This is a randomized clinical trial in U.S. Veterans to evaluate the impact of treatment for obstructive sleep apnea (OSA) on the effectiveness of cardiac rehabilitation, including impact on exercise capacity, disability, and quality of life.
This study is being conducted to determine whether inhaling exhaled carbon dioxide is effective for the treatment of sleep apnea. A mild increase in this gas can stimulate the respiratory drive by 2-3 fold, which in turn can stimulate the upper airway dilator muscles and decrease the severity of obstructive sleep apnea by at least 50% in selected patients.
This study is being done to see if we can improve the way we manage patients' airways. In some instances patients who have a beard, who do not have teeth or have breathing problems during sleep present a challenge to the anesthesiologist. In such patients, it is sometimes difficult to provide air/oxygen for breathing using a mask. The study doctors would like to investigate a new method for holding a mask on the face of those patients. They are interested in comparing a new method against two older methods. They believe the new method will deliver a larger amount of air to the lungs. This information may help doctors provide better care for patients who have beards, no teeth, or breathing problems during sleep.
Diabetes self-management is important to help adults with type 2 diabetes achieve glucose control. Obstructive sleep apnea often co-exists with type 2 diabetes and may act as a barrier to diabetes self-management and glucose control. We will examine if treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP), combined with diabetes education, results in improved diabetes self-management and glucose control.
CPAP is the most effective treatment of obstructive sleep apnea. Oro-nasal masks may be used in case of mouth leaks but these are associated with higher positive pressure needs and lower compliance to treatment. The present investigation evaluates if CPAP compliance would increase when an oral appliance is used in combination with a nasal mask compared to the use of an oro-nasal mask. Eligible patients are those demonstrating a low compliance when using an oro-nasal mask during CPAP therapy. Patients will be treated with automatic CPAP with one of the above-detailed interfaces for 4 weeks and data will be extracted from the machine report in each condition.
to test whether using CPAP can restore the normal pattern of drop of blood pressure during sleep.
Purpose: The purpose of this study is to develop a novel pathway to decrease the cost and waiting time to manage bariatric surgical patients with obstructive sleep apnea. Hypotheses: Compared to the current perioperative pathway, the proposed novel pathway incorporating overnight oximetry and perioperative sleep apnea precautions is safe and more cost effective for evaluating and managing obstructive sleep apnea in the bariatric surgical patients. To decrease the cost and waiting time, we proposed a novel perioperative pathway to manage obstructive sleep apnea in the bariatric patients. In this pathway, the patient will be screened by the STOP-Bang questionnaire. The recruited patients will be randomized into two groups: The STOP-Bang questionnaire score is ≥4 then you will be assigned to any one of these groups - sleep study group (group 1) or - oximetry group (group 2).
The purpose of this study is to determine whether pulmonary arterial hypertension can worsen or even cause sleep apnea. It is hypothesized that if pulmonary arterial hypertension does indeed worsen or cause sleep apnea, then the treatment should first focus on the underlying pulmonary arterial hypertension instead of the sleep apnea. To determine if a person has sleep apnea, they will undergo one overnight polysomnogram (sleep study). If it is found that they have mild to moderate sleep apnea, then the subject will be invited to continue in the study and their pulmonary arterial hypertension will be treated by their managing primary physician. After the subject has had treatment for their pulmonary arterial hypertension, the study center will have them return for a follow up sleep study to learn the effects of pulmonary arterial hypertension treatment management on their sleep apnea, 12-24 weeks after the first sleep study.
The primary objective of the Nuvigil/Provigil Pregnancy Registry is to characterize the pregnancy and fetal outcomes associated with Nuvigil and Provigil exposure during pregnancy.
