Filter by:The investigators hypothesize that obstructive sleep apnea (OSA) may lead to increased formation/accumulation of advanced glycation ends (AGEs), and that the increase in AGEs is contributed in part by increased insulin resistance. The investigators further hypothesize that AGEs contribute to vascular endothelial damage and ultimately atherosclerosis in OSA. The objectives of this study are: 1. To explore the relationship between insulin resistance and AGEs in OSA 2. To study the relationship between AGE and vascular endothelial dysfunction in OSA 3. To study the relationship between AGE and early atherosclerosis in OSA
The purpose of this study is to examine postprandial glucose and lipid metabolism in patients with obstructive sleep apnea.
Obstructive sleep apnea (OSA) is a serious sleep disorder in which a person repeatedly stops breathing or experiences shallow breathing for short periods of time during sleep. The most common treatment for OSA is the use of a continuous positive airway pressure (CPAP) machine, but many people have trouble adhering to the treatment schedule. This study will evaluate the effectiveness of two behavioral therapy programs used in combination with CPAP for improving treatment adherence in people with OSA.
Obstructive sleep apnea is a condition in which people have decreased breathing during their sleep. Untreated sleep apnea has been linked to increased risk for cardiovascular diseases. This research study is looking at blood clotting factors and blood vessel function in health volunteers and patients with newly diagnosed or untreated obstructive sleep apnea to better understand the underlying mechanisms for increased cardiovascular risk.
The purpose of this study is to determine whether respiratory muscle training by means of normocapnic hyperpnea leads to clinical and polysomnographical improvements in patients with mild to intermediate sleep apnea syndrome.
The purpose of this study is to determine the double loop index (DLI) threshold with optimal sensitivity and specificity. The investigators hypothesize that the DLI gives a better reflection of the pathophysiology of the disease than the apnea-hypopnea-index (AHI).
The purpose of the study is to investigate the effect of nasal continuous positive airway pressure in combination with acetazolamide as a treatment for sleep related breathing disturbances in patients with the obstructive sleep apnea syndrome living at low altitude during a sojourn at moderate altitude.
The purpose of this study is to determine whether exchange of the double lumen tube before emergence with a laryngeal mask airway (Proseal) or a tracheal tube will reduce cough at emergence.
The purpose of this study is to assess the prevalence and morbidity rates of sleep disordered breathing in cardiac surgery patients.
The primary objective of the study is to gather data to correlate physiological signals measured by the AVIVO™ Mobile Patient Management System with the patient's respiratory status, including apnea and hypopnea events, during polysomnography
