| Abstract: | Summary Metalized bags for collection and storage of expired air for the study of oxygen consumption in man have been described by Johnsonet al. [J. appl. Physiol.22, 377–379 (1967)]. We have developed a vacuum chamber to permit rapid, multiple sampling with these metalized bags. The reproducibility and reliability of oxygen and carbon dioxide measurements of samples collected with the vacuum chamber compare favorably with accepted standard techniques, such as that of Campney and Pleasants [Res. Quart. Amer. Ass. Hlth phys. Educ.36, 207–210 (1965)]. |
