Lung function measurements in children - copsac

further studies are needed to investigate this possible difference between different types
of equipments. Importantly, other centers using normative data for whole-body
plethysmographs should first consider proper calibration with biologic controls before
applying reference values.
From previous studies it seems that sRaw 50% and sRaw 0.2 were more robust parameters
for asthmatic children. A future study of sRaw accuracy measuring other parameters
than sRaw TOT including subjects with airway obstruction (asymptomatic in a stable
phase) could be beneficial and may show less variability.
