This text/atlas is a unique source of practical information for clinicians who must interpret polysomnography tracings of the neonate, infant, child, and adult. Most atlases show only the images of the various findings; this atlas emphasizes how to actually interpret and report on the polysomnography findings. In the Second Edition, the authors have expanded the captions to include both explanations and helpful hints as well as formal interpretation. The book is organized into sections that allow it to be both comprehensive and practical. This edition has been expanded to cover the breadth and depth of neonatal and pediatric sleep.
