Spirometry, 1892
From: Manual for Physical Measurements in Connection with the Association Gymnasium Records, by Luther Halsey Gulick, published by International committee of Young men’s Christian associations, 1892, page 39.
“After inflating the lungs to their utmost capacity, blow slowly into the spirometer. Three trials may be allowed. Record the greatest one.”
Spirometer, 1907, with breathing mask and one-way valves
From: German archive for clinical medicine , Volume 88, 1907, Page 391. Note the breathing mask and one-way valves. Note also the pen writing on graph paper which was apparently moved horizontally by a screw. Manufacturer unknown.

Spirometer, 1907
From: Hygiene of the lung in health and disease, by Leopold Schrötter (ritter von Kristelli), published by Rebman, 1907, page 12. Likely a dry spirometer, manufacturer was not named.
Alveolar air sampler, 1910
From: Practical Physiology, Edited by M.S. Pembrey, Published by Longmans, Green and Co., NY, 1910, page 183
“The composition of the alveolar air is determined, according to the method introduced by Haldane and Priestley, by an analysis of the last portion of the air expired in an ordinary expiration. The experiment may be performed in the following way. An anaesthetic mask is connected by a T-piece to a piece of tubing 80 cm long and 1.8 cm internal diameter; to the free end of the T-piece is connected (Fig. 181) a gas sampler with a capacity of 50 cubic centimeters. The subject of the experiment fits the mask to his face and makes an ordinary expiration; as soon as the expiration ceases, the tap of the gas-sampler, the air of which has previously been removed be a vacuum-pump or gas-pump, is opened and a sample of the last portion of the expired air is collected before the mask is removed from the face. The analysis of the air is performed in the manner already described. The percentage composition is about 5.5 carbon dioxide, 14.5 oxygen and 80 nitrogen.
Spirometer, Hutchinson, 1910
From: Practical Physiology, Edited by M.S. Pembrey, Published by Longmans, Green and Co., NY, 1910, page 178. Hutchinson’s spirometer still in use, essentially unchanged, over 60 years after his 1846 publication.
