Nitrous oxide has been used for anaesthesia in dentistry since December 1844, where Horace Wells made the first 12–15 dental operations with the gas in Hartford. Its debut as a generally accepted method, however, came in 1863, when Gardner Quincy Colton introduced it more broadly at all the Colton Dental Association clinics, that he founded in New Haven and New York City. Hospitals administer nitrous oxide as one of the anaesthetic drugs delivered by anaesthetic machines. Nitrous oxide is a weak general anaesthetic, and so is generally not used alone in general anaesthesia. In general anaesthesia it is used as a carrier gas with oxygen for more powerful general anaesthetic drugs.Medium size empty blue coloured cylinder with rounded base and painted white neck once containing Nitrous Oxide. A large blue on white diamond shaped label is adhered onto the main cylinder body.Printed on manufacturer's label: 'CIG [logo] / [blank weights table] / DRY / NITROUS OXIDE / C.I.G. (Victoria) PTY.

For medical emergencies at Gabo Island. Unsure if ever used. The portable, manual resuscitator kit is contained in its original green vinyl, hinged case that has corner protectors and two metal front fasteners. Information on the case indicates that it is an ‘Air CIG Viva Resuscitator’. It was used for manual force feeding oxygen into a person’s lungs with the use of a breathing bag, and there are instructions for using the resuscitating bag. The kit was produced by the Commonwealth Industrial Gases Limited, Alexandria, NSW, a company active between 1935 and 1994. An identical kit, which has been accurately dated to 1951, remains at the Cape Otway Lightstation .
