Dupaco Anesthesia Machine

1978 | Object # 0080.0001

By the 1860s, dentists were using nitrous oxide (laughing gas) more widely in their practices. Inhalation sedation was, and is still used, to help patients relax and to amplify the effects of local anesthetic.

Du Pa Co, Inc. was founded in the early 1950s by two engineers, Armand F. DuFresne  and Franklin H. Page. By 1966, the company became Dupaco, Inc. and was making anesthesia machines. 

According to a product catalog, “The Compact 78 from DUPACO Is a real space saver, with all the features of a large apparatus. The basic unit incorporates a completely enclosed 2 Ball Flowmeter unit mounted at the front of the frame at a slight angle to permit easy reading from either a standing or sitting position.”
