Abstract

|
The evaluation of obstructive sleep apnea syndrome (OSAS) should include a through sleep history and a physical examination that includes the respiratory, cardiovascular, and neurologic system. The gold standard approach to diagnosing OSAS is in-laboratory, technician-attended polysomnography (PSG). PSG is should be performed if there is any clinical clues of OSAS such as snoring with apnea, excessive daytime sleepiness, obesity, and so on. There has been considerable controversy about definition of hyponea. If one read a sleep study report, it is important to know both the definition of hyponea and the technology used to detect air flow. Attended in-laboratory PSG has a number of potential disadvantages, including cost, limited availability, and the fact that some patients may sleep poorly in thelab environment. Portable monitoring has been proposed as a substitute for PSG in diagnostic assessment of patients with suspected OSAS.
