Student Learning Outcomes

  • Students will be able to describe the function of all the parts of a fail-safe nitrous oxide/oxygen machine.
  • Students will be able to demonstrate the procedures to safely achieve sedation in patients.

Description

The study of nitrous oxide/oxygen analgesia used in the dental practice. Emphasis will be placed on understanding the mechanism of sedation, risks and benefits associated with nitrous oxide sedation, how to administer and properly document the use of nitrous oxide. Intended for students in the Dental Hygiene Baccalaureate Degree Program; enrollment is limited to students accepted in the program.

Course Objectives

The student will be able to:
A. Identify the physical, chemical and pharmacokinetic properties of nitrous oxide sedation.
B. Analyze the indications and contraindications for use of nitrous oxide sedation in dental procedures.
C. Describe the principles of respiration physiology, individual biovariability and drug titration.
D. Describe and demonstrate use of the armamentarium of nitrous oxide machines, including the function of each part.
E. Demonstrate safe administration of nitrous oxide sedation, including pre and post operative instructions for the patient, proper documentation for a sedation case, the protocol for disinfection of sedation apparatus between patients, on two patients in pre-clinical lab and three patients in a clinical lab.
F. Explain the legal responsibilities of the dental hygiene regarding the administration of nitrous oxide/oxygen analgesia, including the regulations in the California Dental Practice Act and informed consent.
