What medicine is pumping up?

Blowing a balloon means injecting N2O into the balloon for human consumption.

N2O, nitrous oxide, nitrous oxide, commonly known as nitrous oxide (called nitrogen by car fans), is named after the abnormal facial muscles after inhalation, which makes the inhaler smile. This gas has a slight anesthetic effect, which will bring pleasure to inhalers, and excessive inhalation will also be addictive.

Nitrous oxide was discovered by joseph priestley in 1772. humphry davy himself and his friends, including poets Coleridge and robert southey, experimented with this gas in the 1990s. They found that nitrous oxide can make patients lose their pain, and they can still remain conscious after inhalation and will not be unconscious.

Nitrous oxide was soon used as an anesthetic, especially in the field of dentistry. Because dentists usually don't have full-time anesthesiologists, patients often need to stay awake and make oral reactions according to the doctor's advice during the diagnosis and treatment. gas here brings great convenience to dentists.

Extended data:

Nitrous oxide has been used in medicine for a long time as an inhalation anesthetic, but it is rarely used now. 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.
