SPIROMETER MEASUREMENT OF OXYGEN CONSUMPTION BY THE REBREATHING METHOD

CHARLES CLAUDE GUTHRIE, M.D., Ph.D.

As is commonly known, the essentials of rebreathing types of spirometers comprise a distensible closed space, as an elastic bag or spirometer; a supply of oxygen and means for introducing it into the apparatus; an absorber for removing carbon dioxid; connection for a mouth or nose piece or mask; and means for measuring volume changes in the gas. The subject rebreathes for a definite period, usually ten minutes, and the volume change of gas in the apparatus, after correction for pressure, temperature, and water vapor, indicates the amount of oxygen consumed.

Spirometer.

—The spirometer shown in Figure 1 is very satisfactory. It consists of a vital capacity type of spirometer (floating bell form, Fig. 1, A), a soda-lime carbon dioxid absorber (Fig. 1, B), a four way tap (Fig. 1, C), a gas mixing pump (Fig. 1, D), and a tank of oxygen.

The three point suspension of the bell . . . [Full Text PDF of this Article]
