Table 2 Performance of spirometry in general practice (n = 216)
Interpretation of flow-volume curve | n (%) | Bronchodilation test | n (%) |
|---|---|---|---|
Full adherence to ERS | 86 (39.8) | Was not necessary | 138 (36.1) |
Adherence to ERS but only two flow-volume curves | 69 (31.9) | Was necessary and performed | 37 (17.1) |
No adherence to ERS but first flow-volume curve perfect and showing no pathological signs | 13 (6.0) | Was necessary but not performed | 41 (19.0) |
No adherence to ERS showing no obstruction | 15 (6.9) | Â | Â |
No adherence to ERS indicating airway obstruction | 33 (15.2) | Â | Â |
