Excerpt from The Journal of Laboratory and Clinical Medicine, Vol. 5: October, 1919-September, 1920 In this tracing a pithed dog Of kilos weight was arranged for the recording Of uterine contractions (uterus in situ), blood pressure (mercury manometer, right carotid artery), and bronchiole contractions. The method??? used in recording the latter has been fully described previously and need not be discussed here further than to briefly indicate that a special instrument (lung plethysmograph) was inserted air-tight into the sectioned anterior wall Of the Chest. This instrument held the chest wall rigidly expanded and a special artificial respiration machine was used to aspirate air from the chest intermittently. This partial exhaustion of the chest cavity caused air to rush into the lungs through the trachea and expand the lungs. The drum tracing was made by means of a tambour connected to the side tube Of the tracheal cannula. The record thus Obtained shows by its amplitude the amount of air passing into and out Of the lungs at each inspiration and expiration. Contraction of the bronchioles reduces this amount of (tidal) air and simultaneously reduces the amplitude of the lung tracing.
