    What is the problem and what is known about it so far?
    Obstructive sleep apnea (OSA) is a problem in which a person's oxygen levels decrease repeatedly while the person is sleeping due to repeated obstructions occurring at the back of their throat. Although many people with OSA snore, some do not. Without treatment, OSA can lead to daytime fatigue as well as an increased risk for other medical problems, including cardiovascular disease. Treatment frequently involves wearing a specialized mask during sleep. Diagnosing OSA has traditionally required that the patient sleep at a laboratory where special monitors can be applied. More recently, many studies have been performed in patients' homes because it is more convenient. However, many studies done at home have a reduced number of recording channels and do not provide as much information to the physician as laboratory studies.
