Nitrous Oxide is a sweet-smelling, non-irritating, colorless gas which you can safely breathe. Patients receive 50-70% oxygen with no less than 30% nitrous oxide. Patients are able to breathe on their own and remain in control of all bodily functions. Patients may experience mild amnesia and may fall asleep, not remembering all of what happened during their appointment.
You should not utilize Nitrous Oxide if you have been diagnosed with chronic obstructive pulmonary disease (COPD). Though there are no other major contraindications to using nitrous oxide, you may not want to use it if you have emphysema, exotic chest problems, a cold or other difficulties with breathing.
