  • Method and apparatus for determining indirectly the concentration of a specific substance in the blood
    Publication number: 20050135969
    Abstract: Method and apparatus for determining in a person's exhalation air the concentration of a specific substance in the blood by measuring the concentration of the substance and the concentration of water vapor in the exhalation air and utilizing a known relationship between these concentrations. When the method is applied, the exhalation air is exhaled freely in a defined air volume having a predetermined composition, and the concentrations are measured in this air volume. The apparatus for working the method comprises a device which defines a space for receiving the exhalation air, which has two mutually opposite openings through which the space communicates with the surrounding air, and means for selective quantitative detection of the substance in the air in the defined space.
