ANES 4001: Anesthesia Workstations

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.

Learning outcomes

After completing this course, you will be able to:

  • Compare various anesthesia machines and workstations, evaluating how they are used, and analyzing trends in their development.
  • Evaluate the functions, hazards, and applications of vaporizers.
  • Examine various anesthesia machine breathing systems, outlining their principles, components, classifications, structures and functions.
  • Analyze the modes of ventilation and variables seen on anesthesia ventilators.
  • Describe the effects and hazards of trace gas levels and evaluate measures to control and monitor these levels.
  • Perform a machine checkout and explain the rationale for each step.
  • Analyze the uses and evolution airway management equipment.
  • Analyze the uses and evolution of auxiliary equipment.
