简要总结
The study hypothesize that parameters of new function machine---'forced oscillation technique' (FOT) can correlate well with the conventional lung function data for measurement of airway resistance and airtrapping in elderly COPD patients.
详细描述
INTRODUCTION:
Forced oscillation technique (FOT) may be a good supplementary tool to assess lung function in elderly since it is a simple and fast tool requiring minimal patients' cooperation.
AIMS:
To investigate the accuracy of forced oscillation test FOT in assessment of airway resistance and airtrapping in elderly COPD patients by comparing FOT parameters to various conventional lung function parameters including FEV1, FEF 25-75, RV/TLC ratio, IC etc. The best FOT parameter for airway resistance and airtrapping is also determined.
