Abstract: A portable pneumotachograph for determining components of the expiration volume, comprising a processor (3), a PEEP valve (4) mounted on the pneumotachograph (1) on the exhaling side, a filter (5) mounted on the pneumotachograph (1) on the inhaling side for removing the portion of the component in the inspiration air to be determined, at least one sensor (7) mounted in or on the pneumotachograph tube (6), wherein in the sensor (7) disposed on the pneumotachograph tube (6), the pneumotachograph tube (6) having an opening (8) on the sensor side, and/or at least one means configured in the pneumotachograph tube (6) for sampling, and further an optical and/or acoustic control device (9) for the expiration flow. This enables a correlation of measurement data of one or more components of the exhaled flow detected with a lung function test, enabling the localization of the seat of the disease.

Abstract: The invention relates to a process and apparatus for the determination of the parameters of a breath condensate using at least one sensor for the measurement of the parameters and an analysis unit with display for the measurement results. The at least one sensor (2) is positioned in a closed cassette (1), whereby the cassette includes storage containers (4, 5, 6) with flushing solutions and/or solutions for the conditioning of the at least one sensor and/or calibration solutions and/or compounds for the manufacture of a calibration solution and/or for the dilution of the sample solution and/or for elevation of the ion concentration or the conductivity of the sample solution. The storage containers (4, 5, 6) deliver their contents completely or in metered amounts into the cassette and/or onto the at least one sensor (2) under the action of means acting from the outside and through the cassette walls.
