Spirometry is often included in workplace-based respiratory surveillance programmes but its performance in the identification of restrictive lung disease is poor, especially when the prevalence of this condition is low in the tested population.De Matteis, S.Iridoy-Zulet, A. A.Aaron, S.Swann, A...
respiratory defense mechanisms; obstructive and restrictive impairment patterns. Spirometry technique and recognizing testing errors. Measuring the spirogram: FVC and FEV1, back-extrapolation, BTPS correction, repeatability. Interpreting test results: Comparing test results with normal ranges and predicted valu...
This suggests a restrictive pattern of respiratory compromise in the immediate postoperative period, as previously described.4, 14 Postoperative impairment of spirometric measurements was probably not related to insufficient cooperation since all patients were alert and fully compliant within 20 min of ...

RATIONALE: In aging populations, the commonly used Global Initiative for Chronic Obstructive Lung Disease (GOLD) may misclassify normal spirometry as respiratory impairment (airflow obstruction and restrictive pattern), including the presumption of respiratory disease (chronic obstructive pulmonary disease [CO...
Lung function was normal in 39 cases, isolated impairment of DLCO was found in 38 patients, a restrictive defect was present in 27 cases and there was evidence of airflow obstruction in 9 cases. The median duration of symptoms was 10 years. Dyspnoea and an interstitial pattern on chest X-...

CONCLUSION: Persistent impairment of pulmonary function is common in CEP. Concurrent asthma and obstructive defects at diagnosis were predictors for persistent obstructive impairments, whereas reticulation at high-resolution computer tomography and restrictive defect at diagnosis predicted persistent restrictive ...
