| Abstract: | A procedure is described for producing a sulfur dioxide (SO2) contaminated atmosphere within a body plethysmograph, exposing man to this atmosphere while maintaining the SO2 concentration at a given level, and measuring the concentration with less than a oneminute lag time. A syringe is used to introduce incremental volumes of SO2 limiting the maximum SO2 concentration in the chamber and assuring safety of the subject. A Titrilog SO2 analyzer with its rapid response characteristics provides quick measurement of the SO2 concentration. The body plethysmograph used in this manner serves simultaneously as a pulmonary function measuring device and as an exposure chamber. |
