A compact computer printer for quality control spirometric data collection.
Abstract
A new microcomputer, the Datamite III, was tested with a standardized group of known physiologic spirometric inputs. These test inputs were developed by the National Institute for Occupational Safety and Health, and are recommended by the Association for Advancement of Medical Instruments. They exhibit a wide range of flows and volumes along with initial and terminal hesitation in order to test, under the most severe conditions, all aspects of automated data collection, such as initiation and termination thresholds, sampling rate, back extrapolation logic and data reduction. For all measured spirometric parameters, the accuracy of the Datamite III in computing data from these curves was well within all published requirements. Correlation coefficients of 1.000 were obtained between computed and delivered values for forced expiratory volume at 1s (FEV1), forced vital capacity (FVC), FEV1/FVC, and forced expiratory flow between 25% and 75% of the FVC (FEF25-75). In addition, the Datamite III provides maximum technician support for enhanced quality control through unique program features.
