As used in BCEHS, nitrous oxide is supplied as a 50/50 mixture with oxygen and is known as Entonox. Nitrous oxide is a sweet-smelling, colourless gas that is a potent analgesic and a weak anesthetic whose specific mechanism of action is not well understood. It is believed that endorphin release is likely involved in the analgesic effects of nitrous oxide.
The depressant effects of nitrous oxide can be potentiated by the presence of other CNS depressants such as alcohol, sedatives, antihistamines, or psychotropic medications.
