Joseph Priestley, a chemist and Presbyterian minister, discovered nitrous oxide in 1772.1 Its analgesic action was subsequently described in 1800 by Humphrey Davy. Towards the end of the nineteenth century, its anaesthetic properties were recorded under hyperbaric conditions by Paul Bert. Applications for the use of nitrous oxide have developed greatly since that time. It has widespread use in anaesthesia but has many other uses; examples include its use as an aerosol propellant in whipped cream dispensers and for enhancement of engine performance in drag-racing.
