Abstract

Information derived from polysomnography (PSG) provides essential elements for the diagnosis of multiple sleep disorders and therefore is performed commonly in the clinical practice of pediatric sleep medicine. In this chapter, we review the basics of PSG setup, scoring of sleep and its events, standard indications for testing, and interpretation of results. In addition, we provide a more focused discussion for selected neurodevelopmental disorders, as well as practical advice on preparing patients for the night of their sleep study. Beyond standard overnight PSG, we consider the role of specialized testing such as the multiple sleep latency test, maintenance of wakefulness test, and extended PSG in the clinical evaluation of patients. Throughout, areas of uncertainty and possible future directions are highlighted, such as alternative measures of work of breathing and sleep disturbance. Sleep testing remains in flux and an exciting arena for developing improved tools and metrics.
