Medical Nitrous Oxide Gas , Laughing Gas , N2O As A Dissociative Anesthetic
Nitrous oxide has been used for anaesthesia in dentistry since December 1844, where Horace Wells made the first 12–15 dental operations with the gas in Hartford. Its debut as a generally accepted method, however, came in 1863, when Gardner Quincy Colton introduced it more broadly at all the Colton Dental Association clinics, that he founded in New Haven and New York City. The first devices used in dentistry to administer the gas, known as Nitrous Oxide inhalers, were designed in a very simple way with the gas stored and breathed through a breathing bag made of rubber cloth, without a scavenger system and flowmeter, and with no addition of oxygen/air. Today these simple and somewhat unreliable inhalers have been replaced by the more modern relative analgesia machine, which is an automated machine designed to deliver a precisely dosed and breath-actuated flow of nitrous oxide mixed with oxygen, for the patient to inhale safely. The machine used in dentistry is designed as a simplified version of the larger anaesthetic machine used by hospitals, as it doesn't feature the additional anaesthetic vaporiser and medical ventilator. The purpose of the machine allows for a simpler design, as it only delivers a mixture of nitrous oxide and oxygen for the patient to inhale, in order to depress the feeling of pain while keeping the patient in a conscious state.

Nitrous oxide can be used as an oxidizer in a rocket motor.
It is also used as an oxidizer in rocketry and in motor racing to increase the
power output of engines.
It is approved for use as a food additive (also known as E942), specifically as
an aerosol spray propellant.
It is used in surgery and dentistry for its anesthetic and analgesic effects.
It is known as "laughing gas" due to the euphoric effects of inhaling it, a
property that has led to its recreational use as a dissociative anesthetic.
