Nitrous oxide refers to nitrous oxide. It is a greenhouse gas, colorless and sweet, and can be burned under certain conditions as an oxidant. After its discovery, nitrous oxide is used as an anesthetic in medicine, but the risk is very high and it is no longer used. In addition, nitrous oxide is also used in aerospace, food processing and other fields, with a wide range of uses.
What is laughing gas?
Nitrous oxide, chemical formula n2o, is an inorganic substance, the same as oxygen, which can support combustion under certain conditions, but is relatively stable at room temperature. In 1799, it was discovered by British chemist Humphrey David and used as an anesthetic, mostly in the field of dentistry. However, it will cause suffocation when inhaling the mixture of nitrous oxide and air during use, and now it is no longer used as an anesthetic.
Nitrous oxide is used in the aerospace field as a rocket oxidant. Because it is non-toxic and relatively stable, it can ensure the safe flight of rockets, and it can be decomposed into breathable air.
In medicine, it is used together with other drugs to have an anesthetic effect. In food processing, it is used as foaming agent and sealant.
If you inhale nitrous oxide by mistake, you need to quickly run to the fresh air to breathe fresh air. If you have difficulty breathing and cannot supply oxygen, you need external oxygen supply.
