title: [Screening tests for the determination of risk groups in respiratory insufficiency under conditions of epidemiological serial studies].
abstract: A report is given on a system of effective respiratory functional tests which proved its value when used in epidemiological mass examinations in connection with the mass miniature radiography in Berlin, Brandenburg and Halle as well as in mass examinations in Berlin enterprises. Thereby a new development - Pneumotest - is presented, an electronic spirometer for the recognition of ventilatory and distribution analytic preliminary parameters with digital indication of 5 sizes of the breath test manoeuvre which is to be applied as successor of the well-known spirotest device. In this paper the functional capacity of the further developed fluorographic densimetry as preliminary emphysematic test is proved. The application of the rapid helium or O2/N2 breathing back technique for the determination of residual volume and closing volume has in connection with the automatic establishment of the measuring values proved as basic diagnostics for emphysema with a large efficiency and at the same time with high reliability. The digestion of the epidemiological functional data with the help of electronic data processing is carried out in the own microcalculator system following immediately the application during examination.
