Written by the director of a leading center for pediatric sleep medicine, this volume offers authoritative guidance on evaluating sleep in the developing child. The first section of the book provides a thorough understanding of the biological development of sleep, including the development of sleep structure, sleep-related respiratory function, the electrocardiogram during sleep, the electro-olfactogram, electromyogram, and movement behaviors during sleep, and central nervous system function. This section also includes a detailed discussion on the evaluation of the patient history and physical examination. The second section focuses on the appropriate use, techniques, and interpretation of polysomnography at various developmental stages--preterm and full-term neonates, one to twelve months, one to five years, and five to ten years. Also included is a chapter on testing excessive daytime sleepiness in children. The book contains more than 100 reproductions of polysomnographs.
