What to do if patients are not feeling the Nitrous effectively

Possible causes:

  • The mask is not fitting the patients face
  • The one way valve in the nasal cone is missing or stuck in an open position, failing to close upon patient inhalation
  • The breathing bag has a hole, tear, or slit in it
  • Loose hose or connector in the breathing circuit
  • The Room Air Safety Valve is stuck open
  • The nitrous oxide concentration is not set correctly for the patient
  • Some patients do not feel the effects of nitrous oxide
  • Some people self-medicate before going to the dentist
  • Low nitrous flow
  • Too much suction
  • Breathing bag not moving in and out

What to do?

  • Check the system to ensure no leaks in the bag or hoses
  • Verify that the tubes are clear and that there are no kinks
  • Verify that the valves are in place in the nasal hoods
  • Don’t forget about the fit of the mask
  • Ensure breathing pattern is duplicated via the breathing bag
  • Request patients to reveal any medications or alcohol they have taken prior to treatment

Do you service the RA mixer and associated equipment? How often?

Nitrous Oxide Mixers and associated regulators must be maintained as per manufacturers recommendations and accreditation requirements. This is normally 12 months inspection / calibration checks and 5 yearly overhaul of mixers.

How do patients feel on nitrous oxide?

Nitrous oxide is called “laughing gas”, because it produces a “happy state”. You might experience a sense of relaxation, “dreaming” feeling and may smell a faint sweet scent. Nitrous oxide also numbs pain and may help suppress a gag reflex. People under nitrous oxide may feel “tingly” on lips, fingers and legs, flushing in the face as well as sweating.

Is nitrous oxide sedation safe?

Nitrous oxide is possibly the safest sedative in dentistry and has been used for over 100 years. Nitrous oxide is analgesic, works quickly, and doesn’t cause allergies. The level of sedation can be controlled by the concentration given to the patient by the dentist, and sedation can be terminated and reversed anytime by flushing the patient with oxygen. Nitrous oxide sedation is a form of conscious sedation, meaning that patients will remain fully conscious during the treatment and responsive to questions while staying in a comfortable, relaxed state.
