Abstract

The interrupter technique is a convenient and sensitive technique for studying airway function in subjects who cannot actively participate in (forced) ventilatory function tests. Reference values for preschool children exist but are lacking for children > 7 yrs. Reference values were obtained for expiratory interrupter resistance (Rint,e) in 208 healthy Dutch Caucasian children 3-13 yrs of age. A curvilinear relationship between Rint,e and height was observed, similar to published airways resistance data measured by plethysmography. No significant differences in cross-sectional trend or level of Rint,e were observed according to sex. It was found that Z-scores could be used to express individual Rint,e values and to describe intra- and interindividual differences based on the reference equation: ¹⁰logRint,e = 0.645 - 0.00668 × standing height (cm) kPa.L^-1.s^-1 and residual SD (0.093 kPa.L^-1.s^-1). Expiratory interrupter resistance provides a tool for clinical and epidemiological assessment of airway function in a large age range.
