Multiple-breath washout in preschool children--FRC and ventilation inhomogeneity.
The open-circuit multiple-breath inert gas washout method is used to measure functional residual capacity and also to quantify ventilation distribution. The technique is readily applicable in preschool children as it requires quiet tidal breathing. Guidelines for data collection and interpretation in this age group will shortly be published by the European Respiratory Society and the American Thoracic Society.
