The aim of this study was to compare the Spirotel portable
spirometer to a laboratory spirometer...
...Agreement was excellent between spirometers for the measurement of all expiratory
flows, both at baseline and postbronchodilator. More specifically, agreement
between spirometers was as high for measurements of FEF(25-75)
as for proximal flows. High correlations were found between
baseline expiratory flows measured by each spirometer, both in large and small
airways. The portable spirometer was highly sensitive for detecting
small airways obstruction, as compared to the laboratory spirometer. Finally,
the magnitudes of bronchodilator-related flow changes were also highly correlated,
both in large and small airways...
...Spirotel portable spirometer is reliable for measurement of forced expiratory flows, in large and small airways....
