Practice Guideline GuidelineObstructive sleep apnea, polysomnography, and split-night studies: consensus statement of the Connecticut Thoracic Society and the Connecticut Neurological Society.
Obstructive sleep apnea is a state-dependent syndrome. It is characterized by repeated collapse of the upper airway as the result of the loss of waking neuromuscular drive as the brain changes from wakefulness to sleep. This produces a state-dependent decrease in muscle tone, which, together with other predisposing factors such as obesity and anatomical narrowing of the upper airway, results in the spectrum of sleep disordered breathing. ⋯ The efficacy of each depends on the individual anatomy and the severity of the sleep-disordered breathing. CPAP is accepted as the most reliable treatment regardless of anatomy and severity. It is currently the only treatment modality which can be titrated during sleep and requires simultaneous polysomnography.
