Fiberglass plethysmograph. Undated but probably from the late 1960’s. It’s unclear how many of these were actually manufactured.

Plethysmograph, 1963, Constant Pressure-type
A constant pressure-variable volume plethysmograph that appears to have been based on the design of Mead and Emerson. From a doctoral thesis, “Acute effects of inhalation of cigarette smoke on pulmonary mechanics” by John M. Miller, University of Edinburgh, Edmonton, Canada, 1963, page 18.
Pneumotachograph, Godart, 1963
A Godart pneumotach system being used to measure pressure-volume curves. From a doctoral thesis, “Acute effects of inhalation of cigarette smoke on pulmonary mechanics” by John M. Miller, University of Edinburgh, Edmonton, Canada, 1963, page 18.
Spirometer, Godart Pulmotest, 1963

Douglas Bag, Basal Metabolism, Sheep, 1964
From “The Energy Exchange of Ruminants” a PhD thesis paper by John Patrick Joyce for the University of Glasgow, 1964, page 28.
“Photograph of outdoor experimental site demonstrating the collection of sheep by when wearing a face mask.”
“A large pit 9 ft x 4 ft x 1 ft 6 inches was dug just in front of the skeleton framework and was lined with wood. This pit acted as a guard for two large Douglas bags when they were being filled by the animal and prevented them from blowing away. Placing the Douglas bags below ground level also ensured they did not act as a wind shelter for sheep, especially when the bags were filled with exhaled air.”
Spirometer, Palmer, 1963
From “The chromones: History, chemistry and clinical development. A tribute to the work of Dr R. E. C. Altounyan”,
Godart Pneumotachograph, 1962
An amplifier and integrator for a Fleisch pneumotach. From “Pneumotachography” by W.M. Pols,
Spirometer, Spengler, Circa 1960’s
Found on a French Ebay listing. Described (via Google translate) as “Spirometer in very good condition, sold with box but without rubber hose disposable tips. This device calculates the expired volume, needle works fine. Object functional or decorative.” Measured only expiratory volume. The thin tube in the front is a disposable mouthpiece.
Spirometer, Calais 62100, circa 1960’s
A gas meter-type spirometer. Labeled as a Calais 62100. No date but likely from the 1960’s. Found on a Leboncoin listing.
Spirometry, 1960
Found on Getty Images. Captioned as “Twelve year old Susan Cox blowing into a spirometer which will measure any increase in lung capacity after a training session in the pool at the Queen’s Highcliff Hotel.” Photo credited to Harry Todd. Spirometer manufacturer was not named but it could be a Sanborn or Collins spirometer.
