Course Description
Nitrous Oxide is a colorless gas that is used commonly in the
medical and dental professions as a sedative inhalant. Its chemical formula is N2O. English
scientist Joseph Priestley, who is best known for being the first to isolate oxygen, discovered nitrous oxide
in 1793. Priestley initially thought it could be used as a preserving agent, but his attempt to perfect it as
such failed. Humphrey Davy of Bristol, England was the first to experiment with the physiological
properties of the gas. He observed its effects on respiration and behavior as well as its anesthetic
properties. After observing the amusing effects on people who inhaled nitrous oxide, he coined the term
"laughing gas." Despite its potential medical uses, for the next few decades the gas was primarily used as a
recreational drug.
