[Rapid test for quantitative proof of emphysema].
For the purpose of an aimed diagnostics near to practice of unspecific chronic pulmonary diseases a measuring place was developed, by means of which with simple performance of the experiments and short examination-time the determination of vital capacity, forced expiratory volume, maximal breathing capacity, the measurement of the O2-tension of the arterialised ear blood and the determination of the residual volume are possible. The determination of the residual volume is performed according to the classical O2-N2-gasmixture method using the spirotest device in connection with a bag-box system and the PO2-micro-measuring chamber. On 63 patients the residual volume was determined in this measuring place and compared with the rapid He-re-breathing method. The correlation analysis between the RVbody%TK- and the RVO2% TK-values with a correlation coefficient r = 0,887 ascertains the reliability of the demonstrated method. The results of a epidemiological study on 422 test persons on account of the close correlation between RVHe % TK and RVO2% TK with r = 0.62 prove the usability for examinations of the population.
