pneumograph

Now two pneumograph tubes were attached to his chest and abdomen, two metal plates hooked onto his ring and index finger, a blood pressure cuff around his thin upper arm.

Tubes through the wall opposite the food-aperture are used for the introduction of electrical connections, ingoing and outgoing water, the air-pipes, and connections for the stethoscope, pneumograph, and telephone.

The connections for the pneumograph and stethoscope are made with the instruments outside on the table at the left of the bed calorimeter.

Of still more importance, however, is the fact that the expansion and contraction of the pneumograph afford an excellent means for noting the minor muscular activity of a subject, otherwise considered at complete rest.

There should be opportunity for a comfortable adjustment of the stethoscope and pneumograph, etc., and the clothing should be warm enough to enable the subject to remain comfortable and quiet during his sojourn inside the chamber.

This arrangement is possible except in those instances where connections pass clear through from the interior of the chamber to the outside, namely, the food-aperture, air-pipes, water-pipes, electrical connections, and tubes for connections with pneumograph and stethoscope; but the apparatus is so arranged as to have all of these openings in one part of the calorimeter.

Of the five connections appearing through the opening, reading from left to right, we have, first, the rubber connection with the pneumograph, then the tubing for connection with the stethoscope, then the electric-resistance thermometer, the telephone, and finally a push button for bell call.

The pneumograph is placed about the body midway between the nipple and the umbilicus and sufficient traction is put upon the chain or strap which holds it in place to secure a good and clear movement of the tambour for each respiration.

Before the cover is finally put in place, the pneumograph is tested, stethoscope connections are tested to see if the pulse can be heard, the rectal thermometer connections are tested, and the telephone, call-bell, and electric light are all put in good working order.

These are used for electrical connections and for connections with the manometer, stethoscope, and pneumograph.

But it increasingly demanded ever-stranger sensing machines to advance its scientific cause: primitive electrodes; pneumatic tubes and mechanical harnesses that could be attached to the limbs, arms, wings, feet, and legs of unfortunate humans and animals, such as Marey’s air pantographe, which was used to study live birds in flight; recording devices like pneumographs, which graphically represented throat movements produced during vocalization; or tachistoscopic apparatuses that measured how visual sensory impressions could affect consciousness within specified time intervals.
