POLY 3031
Principles of Polysomnography

3.0 Credits


This course is designed to provide the most current information on the technical and clinical aspects of polysomnography, as well as the methodology used by the polysomnographic technologist in the sleep laboratory. This course includes patient interaction and describes the capture of bioelectric activity, overnight recording techniques, the interpretation of data and data presentation for the compilation of the final report.

Delivery Method



Completion of POLY 3011, POLY 3021 and a health professional diploma are strongly recommended.


After completing this course, students will be able to:

  • Describe the basis of the 10-20 system of electrode placement and its advantages, measuring procedures, errors and possible modifications.
  • Describe the general methodology of staging sleep studies.
  • Outline the standardized scoring system for sleep stage scoring.
  • Define, classify, and describe artifacts and their elimination.
  • Describe the physiological aspects leading to arrhythmias during sleep.
  • Give an overview of the multiple sleep latency test (MSLT) and describe the methods used for administering and interpreting MLST.
  • Recognize the need for initial calibrations before an all-night study and describe the presentation of the data provided in a final report.
