AB The specific airway resistance (sRaw) is of potential relevance to lung function testing in preschool children as minimal cooperation is required. However, the thermo hygrometric artefact significantly impacts the measurement during tidal breathing (sRawtb). It may be minimized by the panting method (sRawp) but it is not know whether the conditions necessary for measuring sRawp may be met in preschool children.The aim was to study the feasibility of panting and compare sRawp and sRawtb in preschool children.Sixty five children aged 3.5 – 6.5 years were recruited in a comparative protocol of sRawp vs sRawtb measured in a barometric plethysmograph. Successful measurements of sRawtb and sRawp were obtained respectively in 51 (79%) and 45 (69%) children (X2 = 1.44). The success rate was not dependent on age. sRawtb (11.4 + 2.2 hPa.sec) was significantly larger than sRawp (7.3 + 2.2 hPa.sec, p < 0.001).Thus the faisibility appears similar for sRawp and sRawtb. The measurements however indicate significantly lower estimates during panting, similar to prior reports at school age. The data indicate that panting may represent a valuable alternative to tidal breathing for the routine measurement of sRaw in preschool children.
