The American College of Physicians has released new guidelines on diagnosing obstructive sleep apnea.
The guidelines, published in the Annals of Internal Medicine, recommend a sleep study for patients with unexplained daytime sleepiness.
Polysomnography is the gold standard for diagnosing patients with suspected obstructive sleep apnea, but when polysomnography is unavailable, portable sleep monitors are recommended for patients who don't have serious comorbidities, such as chronic lung disease. Head-to-head trials of different portable sleep monitors are lacking, but indirect evidence suggests that type III monitors are more accurate than type IV monitors. (The Annals article, which is free, includes a table that describes the different types of sleep monitors.)
