Spirometer, Waldenburg’s, 1875

Spirometer_Waldenburg_1875

From: The Virginia Medical Journal, Volume 2, 1875, Page 685. “The principal parts of Waldenburg’s apparatus are two spirometer-like sheet zinc cylinders, fitting one into the other – the outer one meter high and 30 cm in diameter. The outer one is filled to a mark with water, as in the spirometer.  The cover of the inner cylinder has an opening for a manometer, and one for a flexible tube leading to an ori-nasal mask.  If the inner cylinder, resting on the bottom of the outer cylinder, with the stopcock closed is raised and and held by weight, the contained air is rarified; if this cylinder receives air at atmospheric pressure, and the stopcock is then closed, the cylinder being made to descend by weights, the air is condensed.  According to the capacity of the lungs, 5-30 inhalations empty a fully charged apparatus.”

From: Pneutherapy including aerotherapy and inhalation methods and therapy. By Paul Louis Alexandre Tissier. 1903, page 25.  “A U-shaped tube, open to the atmosphere and suitably mounted, is filled with mercury in both branches to the same level which is marked zero.  One branch is connected with a rubber tube and mouthpiece (or mask or nosepiece) used by the person under observation, whose expiratory and inspiratory force is measured by the ascent or descent in the mercury in the other branch, as shown on a millimetric scale.”

Spirometer, Schnitzler’s Double Apparatus for Compressed Air, 1885

Spirometer_Schnitzlers_Double_Inhalation_Apparatus_1885In In the late 1800’s compressed or rarified air was proposed as a treatment for respiratory diseases by Dr. Waldenburg.  This apparatus is based on Dr. Waldenburg’s original device and is a modification of the Hutchinson spirometer.  From The Inhalation Treatment of the organs of respiration including Consumption.  By Arthur Hill Hassal, MD.  1885. In the text of the book Dr. Hassal indicates that this treatment has been found harmful to patients.
