Before there were oxygen bars there were compressed air bars! Compressed air was a therapy championed by Waldenburg but even during his time it was severely criticized. Compressed air was stored in gasometers and then delivered by mask. From Dictionnaire Populare de Medicine, Volume 1, published by Flammarion and Marpon, Paris, 1887, page 52.
A Tissot spirometer being used for basal metabolism. From La Presse Medical, 1927, no. 76, page 1146.
First published description of the Tissot Spirometer. From J. Tissot, “Nouvelle méthode de mesure et d’inscription du débit et des mouvements respiratoires de l’homme et des animaux”, Journal de physiologie et de pathologie générale, 1904, vol 6, pp. 693
A Tissot spirometer (probably 125 liter) used for exercise testing. The subject is inhaling through a gas meter and exhaling into the Tissot spirometer while riding a Monark exercise bicycle. From a University of Texas of the Permian Basin college course synopsis on exercise physiology.

Hutchinson’s spirometer was based on the gasometer, a common device used by scientists, chemists and glassblowers. From Brande, William Thomas, and William James MacNeven. “A manual of chemistry; containing the principal facts of the science arranged in the order in which they are discussed and illustrated in the lectures at the Royal Institution of Great Britain. With plates.” New York, 1829,page 68.
Fronticepiece for Humphry Davy’s “Researches, Chemical and Philosophical”, published in 1800. A mercury-seal gasometer that predates Hutchinson’s spirometer by over 40 years. The counterweight is attached to a cam that varies the force over the range of motion of the bell. This device was used as an air holder, not as a measuring device since the only scale for volume was a uncalibrated dial on the cam. Found on PublicDomainReview.com.
