Today the nitrous oxide is administered in hospitals by a relative analgesia machine, which includes several improvements such as flowmeters and constant-flow regulators, an anaesthetic vaporiser, a medical ventilator, and a scavenger system, and delivers a precisely dosed and breath-actuated flow of nitrous oxide mixed with oxygen.

When used recreationally, nitrous oxide can induce euphoria, relaxation and a hallucinogenic state. [1] Long-term or habitual use can lead to severe neurological damage. [3] Nitrous oxide is said to enhance the effects of psychedelics. [6]
The company prioritized the remaining supply of nitrous oxide to medical customers rather than to food manufacturing. [90] Also, cooking spray, made from various oils with lecithin emulsifier, may use nitrous oxide propellant, or alternatively food-grade alcohol or propane.
The agents in widespread current use are isoflurane, desflurane, sevoflurane, and nitrous oxide. Nitrous oxide is a common adjuvant gas, making it one of the most long-lived drugs still in current use. Because of its low potency, it cannot produce anesthesia on its own but is frequently combined with other agents.
Nitrous oxide is a dental anesthetic that is used as a recreational drug, either by users who have access to medical-grade gas canisters (e.g., dental hygienists or dentists) or by using the gas contained in whipped cream aerosol containers.
Nitrous cut-off or oxygen failure protection device, OFPD: the flow of medical nitrous-oxide is dependent on oxygen pressure. This is done at the regulator level. In essence, the nitrous-oxide regulator is a 'slave' of the oxygen regulator. i.e., if oxygen pressure is lost then the other gases can not flow past their regulator.
Joseph Priestley (1733–1804) was an English polymath who discovered nitrous oxide, nitric oxide, ammonia, hydrogen chloride, and (along with Carl Wilhelm Scheele and Antoine Lavoisier) oxygen. Beginning in 1775, Priestley published his research in Experiments and Observations on Different Kinds of Air , a six-volume work. [ 78 ]
Subsequently, about 40 years later, in 1581, Giambattista Delia Porta demonstrated the use of ether on humans although it was not employed for any type of surgical anesthesia. [14] In modern medicine, Dr. Horace Wells used nitrous oxide for his own dental extraction in 1844.
