Bronchodilator Responsiveness in Healthy Young Adults Using Forced Oscillations Technique (FOT)
Studies evaluating response to bronchodilation in flow-volume spirometry and/or by forced oscillations technique (FOT), have been conduced in subjects with obstructive airways diseases. Less is known about bronchodilation responses, assessed by both spirometry and FOT in healthy young subjects.
The purpose of the present study is
- to determine the range of the bronchodilation response in terms of changes in selected spirometric parameters in healthy non-smoking young adults, for identifying normal response after an inhaled bronchodilatory agent versus placebo, and its anthropometric and spirometric determinants
- to determine the range and characteristics of bronchodilation response using pseudorandom FOT in healthy non-smoking young adults, for identifying normal response after an inhaled bronchodilatory agent versus placebo, and its anthropometric and oscillometric determinants.
- to compare and correlate eventual changes in spirometric and oscillometric parameters.
The investigators hypothesize that exists a normal variation in spirometric and oscillometric parameters after bronchodilation, and that these parameters are correlated.
