Measurement of bronchial responsiveness in young children: comparison of transcutaneous oxygen tension and functional residual capacity during induced bronchoconstriction and -dilatation.


Demonstration of an increased bronchial responsiveness in preschool children may support the diagnosis of asthma. Most young children cannot perform routine lung function tests. Transcutaneous PO2 (PtcO2) measurement has been applied successfully in young children, and changes in PtcO2 have been shown to correlate well with changes in forced expiratory… (More)
