Diagnosis and Treatment of Obstructive Sleep Apnea in Adults
Background: Diagnosis of Obstructive Sleep Apnea (2 of 3)
Polysomnography (PSG), classified as type I sleep monitoring, is the current diagnostic standard for obstructive sleep apnea (OSA). PSG involves an overnight sleep-laboratory study during which neurophysiologic and cardiorespiratory signals are recorded. Sleep studies incorporate a number of assessments and measurements, including recordings of rapid eye movements, electroenchephalogram to detect arousals, chest and abdominal wall monitors to evaluate respiratory movements, electrocardiogram, electromyogram, oximetry, and nasal and oral air flow measurements. Portable sleep monitors (types II, III, and IV sleep monitoring) can and are being used in hospitals, sleep centers, or at-home settings to reduce resource requirements and to obtain results more representative of a typical night’s sleep. Various questionnaires and clinical prediction rules have also been used to assist in decreasing the resources required for diagnosis.
