ANES 4001
Anesthesia Workstations

3.0 Credits


Students explore current practices in the preparation, operation, and troubleshooting of anesthesia delivery workstations. Topics include the structure, function, and operating principles of workstation components as well as information on anesthetic pollution, equipment hazards, and checks and maintenance procedures for anesthesia workstations. Students analyze the uses of airway and adjunct equipment.

Delivery Method

Online, self-paced.

Recommended Requisites

It is strongly recommended that the student be a R.R.T., R.N., M.D. or an equally qualified individual with at least one year of clinical experience prior to taking this course.

ANES 4011: Hemodynamic and Physiological Monitoring

Note: Taking this course does not imply admission to the Anesthesia Assistant program.


After completing this course, students will be able to:

  • Compare various anesthesia machines and workstations, evaluating how they are used, and analyzing trends in their development.
