[Computer measurement of residual volume and alveolar gas distribution parameters in epidemiological studies
Abstract:
Starting from the quick helium-rebreathing-technique of Kowalski-Visser a method of combined measurement of residual volume and closing volume in one test was developed using automatic data - collection in 3 different variants, that is- automatic control during test- manual control during test and- manual control on the table. A computer program running on minicomputer Cellatron 8205 is described. Experiences using the different program-variants are discussed.
