Patient Monitoring for Nitrous Oxide Analgesia Delivery

Recertification Training for the Dental Hygienist & Registered Dental Assistant

This course meets the requirements set forth by the NJ Dental Board to provide three hours of didactic training necessary for recertification of a licensed dental hygienist or registered dental assistant practicing under direct supervision of a licensed dentist to monitor a patient whom the supervising dentist has administered nitrous oxide/oxygen inhalational anesthesia. Particular emphasis will be given to recognition of complications and other untoward events so that participants are able to quickly terminate the nitrous oxide analgesia delivery along with other necessary appropriate steps including summoning the supervising dentist. This course will be in lecture format with group discussion.


Upon completion of this course participants should:
  • Be able to take a medical history and complete a review of systems based upon the patient interview.
  • Recognize and assist in management of common medical emergencies in the dental office.
  • Understand the pharmacology of nitrous oxide and its effects on organ systems.
  • Understand techniques for nitrous oxide analgesia delivery including preoxygenation, titration, monitoring and termination of anesthesia delivery.
  • Be aware of complications of nitrous oxide analgesia administration including their recognition and management.
  • Review safety features of modern nitrous oxide analgesia armamentarium including scavenging and monitoring systems available today.
