Who needs a sleep test? The value of the history in the diagnosis of obstructive sleep apnea

Abstract

Many experts believe that a polysomnogram to screen for obstructive sleep apnea should be performed on every patient who has a history of loud snoring and sleepiness. In contrast, the author believes that with a careful history and physical examination, there is no need to study all such patients, at least not until home polysomnography units become as convenient and economical as pulse oximetry.
