Abstract
Polysomnography or PSG is a multi-parametric test used in the study of sleep; the test result is called a polysomnogram. The name is derived from Greek and Latin roots: ’poly’ (many, Greek), ’somnus’ (sleep, Latin), and ’graphein’ (to write, Greek). Polysomnography provides information on the physiological changes occurring in relation to sleep and wakefulness. Review of clinical history, pre- and post study questionnaires, medications, and technician’s comments at the time of interpreting the PSG provides a unique opportunity to correlate clinical data and to avoid unnecessary testing.
The American Academy of Sleep Medicine (AASM) recently published ”AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specification provides a comprehensive and definitive reference for the evaluation of polysomnograms. The Manual is the result of an extensive review of the literature, analysis and consensus by task forces comprised of renowned sleep experts. It provides standard montages, electrode placements and digitization parameters. Building on the classic manual by Rechtschaffen and Kales, the new manual provides rules not only for scoring sleep stages but also for scoring arousals, respiratory events during sleep, movements during sleep and cardiac events. This new publication will quickly become an essential resource for technologists as they perform and score polysomnographic recordings as well as the physicians who interpret them. The Manual was edited by Con Iber, MD, assisted by a Steering Committee that included Sonia Ancoli-Israel, PhD, Andrew Chesson Jr., MD and Stuart Quan, MD. However, there have been many questions that have been raised since it was published.
This review provided comprehensive details of current literature in polysomnography interpretation:

The review provided the clinicians with the recording conditions that they must be aware of. The character of the polysomnogram begins with the choice of physiological sensors, recording equipment, filter settings, and display montages. The size of the monitor and layout of the tracings also strongly influence the interpretation. A comprehensive polysomnogram must include analysis of sleep stages, sleep-related breathing disorders, limb movements, and sleep fragmentation.
The review integrated up-to-date information and evidence-based knowledge to assist sleep practitioners in the clinical management of variety of sleep disorders; it will help to integrate new technologies in the practice of sleep medicine in Egypt and the Middle East. It will assist in the diagnosis, evaluation and treatment of pediatric sleep disorders patients.
