This book provides an overview of sleep and sleep disorders for practicing clinicians. Sleep disorders represent a major portion of the chief complaints seen by pulmonologists and other clinicians. Patients with sleep-related conditions often present with non-specific complaints that require a broad and detailed knowledge of the wide range of sleep disorders and their consequences.  This concise, evidence-based review of sleep medicine offers a guide to pulmonologists, primary care physicians, and all clinicians involved in caring for patients with sleep disorders. Providing a focused, scientific basis for the effects of sleep on human physiology, especially cardiac and respiratory physiology, chapters also outline a differential diagnosis for common sleep complaints and an evidence-based approach to diagnosis and management. This includes a review of the current standards of practice and of emerging technology and unresolved issues awaiting further research.
