Will this put people to sleep?

No, when using Nitronox, the device always administers 50% nitrous oxide and 50% oxygen ensuring that patients are getting the appropriate amount of nitrous oxide needed for pain or anxiety relief. This ratio is not strong enough to provide anesthesia.

Is nitrous oxide safe?

Nitrous oxide and oxygen have been used for over 100 years and have a long-standing safety record. When the Nitronox device is used – patients are awake (conscious), responsive, and breathing on their own.

Is nitrous oxide flammable?

No, neither N2O or O2 are flammable. However, they are both oxidizers which support combustion. If you have a fuel source, heat source and add an oxidizer – there is potential for hazard. An open firing laser should not be fired at the same time as when Nitronox is being used.

Are there risks?

Nitrous oxide is a “drug” with contraindications for use. There are also occupational concerns and risks to be aware of. Contraindications are very well documented and easy to assess. Occupational risks can be monitored and managed effectively. Additional risks could include combining N2O/O2 with other drugs and medications.

How fast does nitrous oxide take effect and last?

For most patients they will feel the effects of nitrous oxide with in a minute or two. As with any medication the effects may vary from patient to patient. For some it will work great and others it may either not be enough or they will not like how it is making them feel. Once the patient stops inhaling the gas mixture it will be completely out of their system within 5-10 minutes. They will start feeling back to normal almost immediately.
