Abstract
Background: The Diagnosa is a fully integrated system, able to determine spirometry, ECG, blood pressure and body composition. Real time data can be transferred via Internet to a remote receiving center. Objectives: The aim of this study was to perform biological testing of the spirometry component in subjects with normal and pathological pulmonary function. Methods: A group of 45 patients (mean age 43.3 years, 30 males) was tested on both the Diagnosa and the standard Jaeger Masterlab spirometer according to the guidelines of the American Thoracic Society. Three subgroups of 15 subjects each (normal spirometry, obstructive and restrictive airflow limitation) were selected. Results: All measurements performed with the Diagnosa (FVC, FIVC, FEV1, PEF, FEF25, FEF50, FEF75) correlated closely (r = 0.92-0.99) with those performed with the Jaeger spirometer and showed good limits of agreement (the largest difference between the two devices being 0.2 liter for FEV1). Analysis of the 3 subgroups showed no difference for any parameters compared to the overall group. Electronic transfer of all data was successful. Conclusions: The Diagnosa spirometer is comparable to a standard laboratory spirometer and can be used reliably for telemedicine purposes. Copyright © 2001 S. Karger AG, Basel.
