Tripat Deep Singh: basic polysomnography: an algorithmic approach to sleep scoring

Excerpt

Just like obtaining a good quality signal without noise defines the quality of the polysomnogram, similarly, accurate scoring of the collected data defines the quality of the ultimate report. While scoring is an art, it is a formidable challenge especially for the beginners. The American Academy of Sleep Medicine developed “The AASM manual for the scoring of sleep and associated events: rules, terminology and technical specifications’ in 2007” [1]. This document replaced the old Rechtschaffen and Kales (R&K) criteria for sleep scoring. Since then AASM has constantly improved the rules and many versions have been published [2]. Although there is more scientific reasoning, some evidence and standardization, most rules still lack scientific levels of standard practice parameters and the vast majority is based on consensus [3] …
