We thus introduced the SAPADIA normal values (SAP) for lung function interpretation at the Kantonsspital St. Gallen. We currently analyzed the distribution of FVC and FEV1 in non-pulmonary patients with a normal lung function comparing SAP and ECCS (so far 379 lung functions). Data was analyzed using descriptive statistics, Bland-Altman (BA) analysis and linear regression. Estimated bias and precision were calculated.For FEV1 we observed a significant difference between ECCS and SAP only in elderly men (>59 y.o.) (7±336 vs. 122±336 ml/s). When comparing FVC using SAP, the Bland Altman analysis revealed a bias, which was significantly lower using ECCS (e.g. in men bias of SAP was 0.33 l (0.27-0.39), bias of ECCS was 0.18 l (0.11-0.24), (fig.1, lower panels).In summary, SAP tended to overestimate FVC and FEV1 in eldery men compared to ECCS. However, absence of a pulmonary consultation in our population does not exclude a slight impact of the underlying disease on lung function.We consider SAP for FEV1 and FVC appropriate for the measurement of lung function of our population. Cut-off values require special attention especially in elderly. ER -
