[A microprocessing system for respiratory epidemiological studies (author's transl)].

A microprocessing system designed to collect and analyse data from respiratory epidemiological studies is described. It has several independent modules. The first module presents the questions from the European Coal and Steel Community questionnaire in a logical sequence and analyses and stores the responses. The second module is associated with a device that measures CO diffusion and determines gas exchange; it calculates, displays and stores the results. The last module collects and integrates digitally the flow measured at the mouth by a pneumotachograph during forced expiration, then displays and calculates the principal indices when certain programmed criteria for selection of flow-volume curves are met. All modules are connected to a numerical magnetic tape-recorder which centralizes the information data. The system is easily transportable and satisfactory for epidemiological studies.
