Computer-Assisted Spirometry Data Analysis for the National Health and Nutrition Examination Survey, 1971-80

摘要

The equipment, procedures, and data reduction methods employed in the National Health and Nutrition Examination Survey for the collection and analysis of spirometric data are described. Data variability and testing methodology are discussed, as the influence of milieu and technician training. The computer programs that drive the data reduction and calibration are detailed, as are the algorithms used in the calculation of various spirometric parameters. The algorithms chosen for the determination of certain critical parameters are documented and validated.
