Measurement & interpretation
Key spirometry parameters are calculated including FEV1, FVC, PEF, VC, FEV1/FVC and FEF 25-75% alongside numerical data for predicted, measured and percentage difference. Interpretation is automatically calculated and can include the Global lung initiative (GLI). The supplied software will also calculate and interpret according to the ATS/ERS 2019 guidelines update on the standardisation of spirometry.
