This guide gives a good overview of the basics of polysomnography. The sections on artifacts, scoring, and EKG may be especially useful for new clinicians and students who are unsure of what they see when viewing a polysomnographic tracing. The author is very credible and is a leader in the field, having written "Principles of Polysomnography".
