Depending on the subpopulation, obstructive sleep apnea (OSA) can affect more than 75% of surgical patients. An increasing body of evidence supports the association between OSA  and perioperative complications, but some data indicate important perioperative outcomes do not differ between patients with and without OSA. In this review we will provide an overview of the pathophysiology of sleep ap...

OBJECTIVE To determine the effect of tracheotomy on polysomnographic and arterial blood gas data in patients with obstructive sleep apnea (OSA). DESIGN A retrospective study of all patients who underwent tracheotomy and were studied polysomnographically at the Johns Hopkins Sleep Disorders Center, Baltimore, Md, since 1981. SETTING A regional sleep disorders center. PATIENTS Twenty-eight ...

I. POLICY Pharyngometry and rhinometry are considered investigational as techniques for screening, diagnosis, or treatment planning in persons with known or suspected obstructive sleep apnea (OSA) and for all other indications. There is insufficient evidence to support a conclusion concerning the health outcomes or benefits associated with these procedures Cross-references MP 2.045 Diagnosis an...

Background: Owing to the lack of clear guidelines, significance obstructive sleep apnea (OSA) screening in healthy community people is unclear. This study aimed screen for OSA a population and provide basis its screening.

BACKGROUND Previous reports have documented the coexistence of obstructive sleep apnea (OSA) and epilepsy and the therapeutic effects of treatment on seizure frequency and daytime sleepiness. The authors' objective was to determine the prevalence of OSA and its association with survey items in a group of patients with medically refractory epilepsy undergoing polysomnography (PSG). METHODS Thi...

Glutamate and γ-aminobutyric acid (GABA) are the two main neurotransmitters in human brain. The balance between their excitatory inhibitory functions is crucial for maintaining brain’s physiological functions. Disturbance of glutamatergic or GABAergic neurotransmission leads to serious health problems including neurodegeneration, affective sleep disorders. Both GABA glutamate involved control s...

OBJECTIVES Obstructive sleep apnea (OSA) is a common clinical problem that can have serious health consequences and complicate the course of mental disorders. It is estimated that the prevalence of sleep apnea in patients with bipolar disorder can be 21-47.5%. Some symptoms of OSA are the same as the symptoms of depression: daytime drowsiness, cognitive dysfunction, decreased drive, apathy, dep...

BACKGROUND Obstructive sleep apnea (OSA) and central sleep apnea are common in patients with heart failure. We hypothesized that in such patients, severity of OSA is related to overnight rostral leg fluid displacement and increase in neck circumference, severity of central sleep apnea is related to overnight rostral fluid displacement and to sleep Pco(2), and continuous positive airway pressure...

We hypothesized that in such patients, severity of OSA is related to overnight rostral leg fluid displacement and increase in neck circumference, severity of central sleep apnea is related to overnight rostral fluid displacement and to sleep PCO2, and continuous positive airway pressure a...

Obstructive sleep apnea (OSA) affects 2% to 4% of middle-aged adults. It is even more common in the elderly. Although the primary care physician has the opportunity to play a pivotal role in the detection of this disorder, most physicians have had little or no formal training in OSA; and they frequently underdiagnose the disorder. The Walla Walla project demonstrated that with several education...
