Toxicology of nitrous oxide

Acute toxicity: nitrous oxide, as an inhalation anesthetic, has been used in medicine for a long time and is rarely used. Inhaling the mixture of nitrous oxide and air will cause suffocation when the oxygen concentration in it is very low; Inhalation of 80% mixture of nitrous oxide and oxygen causes deep anesthesia, and there is generally no sequelae after awakening.

Nitrous oxide, commonly known as "nitrous oxide", is an anesthetic gas and has been widely used in medical surgery. However, "nitrous oxide" will lead to hypoxia after entering the blood, and long-term smoking may lead to high blood pressure, syncope and even heart attack. In addition, long-term exposure to such gases can also lead to anemia and damage the central nervous system.
