“Truly a comprehensive collection of invaluable information and graphical illustrations about everything that is needed to perform the polysomnographic assessment. From basic concepts about normal sleep and sleep disorders, technical information about calibration, artifacts, and various montages, to practical recommendations for managing a sleep laboratory, this atlas represents a superb reference guide. The atlas is filled with useful illustrations of actual records depicting standards for monitoring, artifacts recognition, and key findings associated with different sleep pathologies. A compendium of review questions at the end of each chapter is extremely handy for testing new learning. Although intended primarily for sleep technologists, this atlas will serve as a useful reference for any sleep clinician, researcher, or trainee wanting to learn more about the technical and clinical aspects of evaluating sleep and sleep disorders.The authors of this atlas, Drs. Ravi Gupta, S. R. Pandi-Perumal, and Ahmed BaHamman, are internationally known leading experts in sleep medicine and sleep research. They are to be commended for compiling this essential tool for a better understanding normal sleep and diagnosing many sleep disorders. This atlas is likely to remain a key reference in the field for years to come.”
—From the Foreword by Charles M. Morin, PhD, FRSC, DABSM, President, World Sleep Society

“The Clinical Atlas of Polysomnography, written by 3 of the most renowned sleep researchers worldwide, is one of most comprehensive books written in this context. The book is easy to understand and generously illustrated. In addition to the substantial coverage of polysomnography, this book also presents information on sleep in general and different sleep disorders and how to make diagnoses. This book is not only of great value for sleep technologists but is also most valuable for physicians interested in sleep disorders, which every physician should be aware of, as sleep is one of the crucial fundaments we have to consider to stay alive, and sleep disorders are one of most common issues we faces in health care.”
—Jan Ulfberg, MD, PhD, Assistant Professor, Sleep Specialist, Sweden

“Easy to understand, compre¬hensive and one can begin a career in sleep medicine by simply reading it. . . . Sleep disorders are now recognized as a major public health issue. Investigating sleep is the most challenging medical investigation as it requires background knowledge of physiology, sleep medicine, and expertise in sleep technology. The Clinical Atlas on Polysomnography has everything you want to learn or teach on sleep technology. The physiological principles of respiration, gas exchange, and the genesis of electrical potentials with color illustrations make it easy to understand for technicians. . . . Recent developments in sleep data acquisition systems and analysis software, including automated computing techniques, make the life of sleep technicians ever-challenging. This book describes all the major PSG machines available in the market with their software features.” — From the Foreword by Hrudananda Mallick, MD, PhD, FAMS, Professor, Physiology, Dr. Baldev Singh Sleep Laboratory, All India Institute of Medical Sciences, New Delhi, India

Written for sleep technologists, Clinical Atlas of Polysomnography is a comprehensive guide to basic information regarding normal sleep, sleep disorders, and electrophysiology that is outside of the scope of the AASM manual (AASM Manual for the Scoring of Sleep and Associated Events). It aims to act as a guide through the fundamental aspects of, for example, types of overnight sleep study, establishing a sleep laboratory, preparing the patient for a sleep evaluation study, placement of electrodes and leads, and the scientific aspects of such placement, i.e., why they are placed at that particular position. This information will be very useful in those parts of the globe where formal training in sleep technology is not yet available.

Many further chapters focus on depicting real-time illustrations of sleep data as captured in the sleep laboratory and the scoring of recording data. Information regarding common montages, artifacts, and troubleshooting in the sleep laboratory will facilitate the reader’s journey as a trainee sleep technologist. While scoring sleep recordings, the “When you score the data” histogram can provide a great deal of useful information, and this has been explained in detail in this book. Most importantly, the volume explains how to write reports that are both informative and easy to understand by physicians who do not have advanced knowledge of sleep medicine. Lastly, the authors provide ready-made forms, questionnaires, and documents that can either be used as they are or with some modifications.

This up-to-date and comprehensive volume will be an invaluable guide for technicians and physicians who wish to practice sleep medicine and for sleep technology and physician training programs. The volume is intended to complement, not be a substitute for, the AASM scoring manual, as many areas that are covered in the manual are not covered here.

Key features of the book:

  • Discusses the principles of polysomnographic technology
  • Explains sleep laboratory management
  • Provides a practical approach to scoring of sleep studies according to the latest AASM rules epoch by epoch
  • Provides a practical approach to the application and titration of positive airway pressure therapy and supportive oxygen therapy
  • Functions as a step-by-step guide to troubleshooting
  • Provides a framework to document and maintain records in sleep laboratories
  • Includes illustrations to provide better understanding of polysomnography
  • Presents case studies that will be helpful for new sleep physicians
  • Functions as a comprehensive guide for the person new to sleep technology
