[Determination of the lung function by impulse oscillometry in 549 healthy children in Chengdu area].


OBJECTIVE Impulse oscillometry (IOS) is a new method for determination of breathing mechanics, which features convenient operation, good repeatability and wider range analysis. As there is no standardized normal value in China at present, this study will provide a normal value of lung function determination by impulse oscillometry for children in Chengdu… (More)
