POLY 3021: Polysomnography Instrumentation

This course introduces instrumentation and electrical principles and practices that the polysomnographer must understand. While electrical safety and ancillary equipment encountered in sleep laboratories are covered, the student will also cover the internal workings and calibration of the polygraph. Amplifiers and filters will be emphasized along with basic tracings and some of the artifacts that may appear and influence one’s interpretation of the sleep study. Also, the international “10-20” system of electrode placement will be introduced.

Objectives

After completing this course, students will be able to:

  • Outline the fundamental principles of electricity and describe the hazards, features, and protocols of electrical safety.
  • Describe bioelectrical potentials, polygraphs, calibration, electrode placement, signal derivation, and EEG tracing.
  • Describe the structure and function of ancillary equipment and how it is used to monitor and collect data.
